Description

The present invention relates to an information processing device, an information processing method, and a program for quickly performing device maintenance such as error processing on a device and replenishing consumables.

Conventionally, device management systems have been known that perform maintenance of devices (e.g., image forming devices) installed in an office or the like via a network. By using a device management system, for example, it is possible to detect via the network when a failure occurs in a device or when it is necessary to replenish consumables, and to respond promptly. For example, the following Patent Document 1 is known as a document disclosing a device management system.

A known conventional device management system includes a management server that manages each device in a centralized manner, and an information processing device that acts as a monitoring device that collects operation information from multiple devices and transfers it to the management server. Operation information includes status information related to device failures and consumables, as well as counter information, sensor information, log information, and the like. The operation information is used by the management server to perform device management services, device maintenance services, and the like. The monitoring device obtains this operation information from each device, for example, by using a method such as periodic polling.

If a failure occurs in a device, depending on the type of failure, a worker may need to go to the device's location to perform recovery work. For this reason, in order to reduce the time from the occurrence of a failure to recovery, i.e., downtime, it is desirable for the device management system to operate stably.

In the device management system of Patent Document 1, the monitoring device has an internal proxy function (hereinafter simply referred to as a "proxy") that relays communication of management data (operation information). Furthermore, settings for using the proxy of the monitoring device are also made for the managed device. As a result, the management data is sent from the device to the management server via the proxy of the monitoring device.

Patent Publication 2018-136876

When managing devices using the proxy function of a monitoring device, as in the system disclosed in Patent Document 1, if the proxy function of the monitoring device is not working properly, the management server cannot receive and manage the operation information.

In addition, when a monitoring device uses a proxy function, the proxy settings of the device are configured to correspond to the proxy settings of the monitoring client. If a device only has one type of proxy setting, for example, if a problem occurs in the proxy function of the monitoring device, this may affect other functions in the device that use the proxy settings.

The present invention has been made to solve the above problem, and aims to provide a mechanism for an information processing device equipped with a proxy function to recognize that an abnormality has occurred in the proxy function.

An information processing device according to one embodiment of the present invention is an information processing device that monitors a plurality of network devices , and comprises: a monitoring means for acquiring operation information from the network device to be monitored upon request from the information processing device when the registration information of the network device to be monitored is first information, and transmitting the acquired operation information to a management server via a network; a proxy means for operating as a proxy server for the network device when transmitting information from the network device to the management server; and a confirmation means for confirming whether the proxy means is operating normally as the proxy server when the registration information of the network device to be monitored is second information different from the first information, wherein the second information is information corresponding to a setting for transmitting the operation information to be acquired by the monitoring means from the network device to the management server via the proxy server, rather than upon request from the information processing device .

The present invention has the advantage of being able to recognize that an abnormality has occurred in the proxy function of an information processing device.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[First embodiment]
A first embodiment of the present invention will be described with reference to FIGS.

<System Configuration>
FIG. 1 is a conceptual diagram showing a network configuration of a management system according to the present embodiment.
The management system of this embodiment is a system for managing image forming apparatuses, and includes one or more image forming apparatuses 101 , a monitoring apparatus 102 , and a management server 103 .

In FIG. 1, an image forming device 101 corresponds to the "network device" of the present invention, and is a managed object of the management system according to this embodiment. For example, a digital multifunction device that executes jobs such as copying and printing can be used as the image forming device 101. Also, other devices such as a single-function printer, scanner, copier, or three-dimensional printer may be used instead of the image forming device 101.

The monitoring device 102 is connected to each image forming device 101 via a network such as a LAN (Local Area Network) 105. The monitoring device 102 acquires operation information, i.e., data related to the occurrence of failures and the replenishment of consumables, from each image forming device 101. The monitoring device 102 transmits the acquired operation information to the management server 103.

The management server 103 is connected to the monitoring device 102 via a network such as a WAN (Wide Area Network) 104. As described below, the management server 103 centrally manages the monitoring device 102 and each image forming device 101. This management uses operation information received from the monitoring device 102. The management server 103 may be configured to include one computer or multiple computers. Furthermore, a computer using cloud computing technology may be used as the management server 103. As shown in FIG. 1, the management server 103 may be directly connected to the image forming device 101 via the WAN 104 and LAN 105.

<Hardware Configuration of Image Forming Apparatus>
FIG. 2 is a block diagram illustrating an example of a hardware configuration of the image forming apparatus 101. As shown in FIG.
2, the image forming apparatus 101 of this embodiment has an overall control unit 211. The overall control unit 211 controls interfaces with external devices 212 to 215 and a network 217 (such as the LAN 105) connected to the image forming apparatus 101, and also controls the operation of the entire image forming apparatus 101.

The CPU 201 functions as a controller that controls the entire system. To achieve this, the CPU 201 reads out control programs from the ROM 202 and the HDD 205. When reading out a control program from the HDD 205, the reading out is controlled by the disk controller (HDC) 204. The CPU 201 then controls the various components 207 to 210 and 216 that are connected via the system bus 206.

The RAM 203 is used as a work area when the CPU 301 executes the control program.
The reader I/F 207 is connected to a reader unit 212 (described later) and controls the operation of the reader unit 212 .

The printer I/F 208 is connected to a printer unit 213 (described later) and controls the operation of the printer unit 213 .
The operation unit I/F 209 is connected to an operation unit 214 and performs processes such as transmitting user operation information input from the operation unit 214 to the CPU 201 and controlling the display of the operation unit 214 based on information received from the CPU 201.

The switch I/F 210 is connected to a switch unit 215 and transmits the on/off state of the switch unit 215 to the CPU 201 .
The reader unit 212 reads an image of an original document under the control of the reader I/F 207. Then, in response to an instruction from a user, the reader unit 212 performs a process of causing the printer unit 213 to print out image data corresponding to the original document image, and a process of storing the image data in the HDD 205. Furthermore, the reader unit 212 can also perform a process of transmitting the image data output by the reader unit 212 to an external computer or the like via a network 217.

The printer unit 213 prints out the document read by the reader unit 212 and the image data read from the HDD 205 under the control of the printer I/F 208. Furthermore, the printer unit 213 receives and executes print jobs from an external computer or the like via the network 217.

The operation unit 214 includes, for example, a keyboard, a pointing device, a display device, etc., and accepts user operation input and displays information to the user. The operation unit 214 may also be a display device with a touch panel.

A switch unit 215 controls the on/off state of switches and the like used by the user to operate the image forming apparatus 101 .
A network (NW) I/F 216 is connected to a network 217. Through this network I/F 216, the overall control unit 211 communicates with other information devices on the network 217.

<Hardware configuration of monitoring device and management server>
3 is a block diagram showing an outline of an example of the hardware configuration of the monitoring device 102 and the management server 103. In this manner, the monitoring device 102 and the management server 103 have the same hardware configuration.

In FIG. 3, a communication I/F unit 301 is a network interface for communicating with external systems, devices, and the like.
The storage device 302 stores an operating system (OS), programs, operation information, data collected from external systems and devices, and the like.

The CPU 303 loads a program from the storage device 302 into the memory 304 and executes it.
That is, the memory 304 is used as a working memory for the CPU 303 .
The output I/F unit 305 is connected to an output device such as a display device, and outputs the results of program execution.

<Software configuration of monitoring device>
FIG. 4 is a block diagram showing an example of a software configuration (functional configuration) of the monitoring device 102. As shown in FIG.
In FIG. 4, an acquisition unit 401 acquires data such as operation information from the image forming apparatus 101 .
The transmission unit 402 sends the acquired operation information, etc. to the management server 103 .

The data management unit 403 performs processing such as storing acquired operation information and managing device information of the image forming apparatus 101 to be managed.
The proxy server 404 relays data communication between the image forming apparatus 101 and the management server 103. In addition to the proxy server 404, another proxy server may be provided on the communication path between the image forming apparatus 101 and the management server 103.
The monitoring unit 405 monitors the operating state of the proxy server 404 and also performs processes such as starting and stopping the proxy server.

<Operation of monitoring device>
FIG. 5 is a flowchart illustrating an example of processing performed by the monitoring unit 405 of the monitoring apparatus 102. As shown in FIG.
In this embodiment, the monitoring unit 405 monitors the operation state of the proxy server 404 at each predetermined monitoring timing. Therefore, the monitoring unit 405 waits until the time reaches the monitoring timing (step S501). When the time reaches the monitoring timing, the process proceeds to step S502.

Here, the monitoring timing may be a predetermined time, may be a time when a predetermined time has elapsed since the previous monitoring process, or may be determined based on other criteria.
In step S 502 , the monitoring unit 405 executes a process for checking the operating status of the proxy server 404 .

Then, in step S503, the monitoring unit 405 determines, based on the result of checking the operation state, whether the proxy server 404 is operating or stopped. If the proxy server 404 is operating, the process ends.
On the other hand, if it is determined in step S503 that the proxy server 404 has stopped, the monitoring unit 405 restarts the proxy server 404 in step S504.

As described above, in this embodiment, the monitoring unit 405 automatically determines at a predetermined timing whether the proxy server 404 of the monitoring device 102 is operating, and restarts the proxy server 404 if it is stopped. Therefore, according to this embodiment, the information processing device can recognize that an abnormality has occurred in the proxy server 404.

[Second embodiment]
In the first embodiment, the monitoring device 102 monitors its own proxy server 404, and restarts the proxy server 404 if it is stopped. However, it is also possible that restarting the proxy server 404 fails. In this embodiment, a configuration for transmitting data from the image forming device 101 to the management server 103 without using the proxy server 404 if restarting the proxy server 404 fails is added to the management system of the first embodiment.

A second embodiment of the present invention will now be described with reference to the drawings.
The network configuration and hardware configuration of the image forming device 101, monitoring device 102, and management server 103 according to this embodiment are the same as those of the first embodiment (see FIGS. 1 to 3). On the other hand, the software configurations of the monitoring device 102 and management server 103 differ from those of the first embodiment in the following points.

<Software configuration of monitoring device>
6 is a block diagram showing an example of a software configuration of the monitoring device 102 according to the present embodiment. In FIG. 6, components having the same reference numerals as those in FIG. 4 are the same as those in FIG.

The monitoring device 102 of this embodiment differs from the monitoring device 102 of the first embodiment in that it includes a device management unit 406. This device management unit 406 changes the proxy settings of the image forming device 101 and starts and stops a self-monitoring function (described later) provided in the image forming device 101.

<Software Configuration of Image Forming Apparatus>
FIG. 7 is a block diagram showing an example of the functional configuration of the image forming apparatus 101. As shown in FIG.
7, a receiving unit 601 receives a request from an external device. For example, the request is a request to have a self-monitoring unit 604 (described later) collect operation information and the like within the image forming apparatus 101.

The transmitting unit 602 transmits a response to the request received by the receiving unit 601 to the monitoring device 102 or the like.
The setting unit 603 performs various settings, such as proxy settings, based on information specified by the monitoring apparatus 102 or the like.

The self-monitoring unit 604 monitors the state inside the image forming device 101. The self-monitoring unit 604 then sends the data indicating the monitoring results, which is specified by the monitoring device 102, to the transmitting unit 602 according to a predetermined schedule, and causes the data to be transmitted to the monitoring device 102.

<Operation of monitoring device>
FIG. 8 is a flowchart illustrating an example of the operation of the monitoring device 102 according to this embodiment.
As in the first embodiment, the monitoring unit 405 waits until the time reaches the monitoring timing (step S501), and then checks the operation state of the proxy server 404 (step S502). If the proxy server 404 is operating, the monitoring unit 405 ends the process, and if it is stopped, the monitoring unit 405 restarts the proxy server 404 (step S504).

Next, the monitoring unit 405 checks whether the restart of the proxy server 404 has been successful (step S701). If the restart has failed, the process proceeds to step S706.
On the other hand, if the restart has been successful, in step S702, the data management unit 403 searches for an image forming apparatus that is collecting data by polling despite having a self-monitoring unit 604 among the image forming apparatuses 101 to be managed.

As described above, if the image forming device 101 has the self-monitoring unit 604, it can collect operation information under its own control and transmit it to the management server 103 via the proxy server 404 of the monitoring device 102. However, if the self-monitoring unit 604 is not set to be used, the image forming device 101 does not collect operation information under its own control, but transmits data in response to the polling function of the monitoring device 102. Also, there are cases where an image forming device that does not have the self-monitoring unit 604 and therefore cannot collect operation information under its own control (an image forming device that can only transmit data in response to the polling function) is placed under the management of the management system.

Figure 9 shows an example of a management information table, i.e., a table for registering information for managing an image forming device. This management information table is managed by the data management unit 403 of the monitoring device 102.

In FIG. 9, "device ID" is information for uniquely identifying an image forming device within the system.
The "serial number" is information for uniquely identifying the image forming apparatus from among a group of products provided by the same manufacturer.
"IP address" is the IP address assigned to each image forming device.

The "self-monitoring function" is information indicating whether or not each image forming apparatus has a self-monitoring function (whether or not each image forming apparatus has the self-monitoring unit 604).
The "management method" is information indicating whether the monitoring apparatus 102 performs management using the self-monitoring unit 604 or whether it collects and manages operation information by regular polling.

The information shown in FIG. 9 is determined and registered based on the information obtained from each image forming device when registering the image forming device as a management target. Of course, it is also possible to manage image forming devices using information of a different type than the information shown in FIG. 9.

Returning to the flowchart of FIG. 8, if an image forming device that has a self-monitoring unit 604 but collects operation information by polling is found in step S702, the data management unit 403 of the monitoring device 102 notifies the setting unit 603 of the image forming device of the proxy information of the proxy server 404. The setting unit 603 then performs proxy settings for the image forming device 101 based on the proxy information (step S703).

Next, the device management unit 406 of the monitoring apparatus 102 instructs the self-monitoring unit 604 of the image forming apparatus 101 to start a self-monitoring operation (step S704).
Thereafter, the data management unit 403 of the monitoring apparatus 102 rewrites the "management method" column of the corresponding image forming apparatus 101 in the registered information of the management information table (see FIG. 9) from "polling" to "via proxy" (step S705).

The processes in steps S703 to S705 are executed for all image forming apparatuses that are equipped with the self-monitoring unit 604 and collect operation information by polling.
On the other hand, if it is determined in step S701 that the restart of the proxy server 404 has failed, the data management unit 403 searches for an image forming device 101 that is being managed using the proxy server 404 from among the image forming devices under management (step S706).

When an image forming apparatus 101 that uses the proxy server 404 for management is found, the device management unit 406 notifies the setting unit 603 of the image forming apparatus 101 of the "empty" setting. The "empty" setting is the proxy information that was set before the image forming apparatus 101 was registered as a management target. The setting unit 603 then sets the proxy settings for the image forming apparatus 101 based on this proxy information (step S707). Note that the proxy information before registration is proxy information that allows the image forming apparatus 101 to communicate without going through the proxy server 404 of the monitoring apparatus 102. This proxy information may be obtained from the image forming apparatus 101 and saved, for example, when the image forming apparatus 101 is set as a management target.

Next, the device management unit 406 of the monitoring apparatus 102 instructs the self-monitoring unit 604 of the image forming apparatus 101 to stop the self-monitoring operation (step S708).
Thereafter, the data management unit 403 of the monitoring apparatus 102 rewrites the "management method" column of the corresponding image forming apparatus 101 in the registered information of the management information table (see FIG. 9) from "via proxy" to "polling" (step S709).

The processes in steps S 707 to S 709 are executed for all image forming apparatuses that are managed using the proxy server 404 .
As described above, in this embodiment, if the proxy server 404 of the monitoring device 102 fails to restart, the image forming device 101 can be returned to a setting that does not use the proxy server 404. As a result, according to this embodiment, if the proxy server 404 cannot return to a normal operating state, it is possible to switch to management by polling.

[Third embodiment]
The network configuration, hardware configuration, and software configuration of the image forming device 101, monitoring device 102, and management server 103 according to this embodiment are almost the same as those of the first embodiment (see FIGS. 1 to 4). However, the operation of the monitoring device 102 differs from that of the first embodiment in the following points.

In the first embodiment described above, in order to determine whether the proxy server 404 is normal or abnormal, it is decided to check whether the proxy server 404 is operating (see steps S502 and S503 in FIG. 5).

However, even if the proxy server 404 is in operation, it may not be operating normally due to an internal malfunction of the proxy server 404 .
In contrast, in this embodiment, instead of the same process as in the first embodiment (see FIG. 5) or in addition to the same process as in the first embodiment, the following process is performed.

<Operation of monitoring device>
FIG. 10 is a flowchart illustrating an example of the operation of the monitoring device 102 according to the present embodiment.
The monitoring unit 405 monitors the operation state of the proxy server 404 at each predetermined monitoring timing. To this end, the monitoring unit 405 waits until the time reaches the monitoring timing (step S901). When the time reaches the monitoring timing, the process proceeds to step S902.

Here, the monitoring timing may be a predetermined time, may be a time when a predetermined time has elapsed since the previous monitoring process, or may be determined based on other criteria.
In step S 902 , the monitor unit 405 communicates with the management server 103 via the proxy server 404 .

Next, in step S903, the monitor unit 405 determines whether the communication in step S902 was successful or not, and if the communication was successful, ends the process.
On the other hand, if it is determined in step S 903 that the communication has failed, the monitor unit 405 communicates with the management server 103 without passing through the proxy server 404 in step S 904 .

Next, in step S905, the monitoring unit 405 determines whether the communication in step S902 was successful.
If it is determined in step S905 that the communication has been successful, the monitor unit 405 restarts the proxy server 404 (step S906).

On the other hand, if it is determined in step S905 that communication has failed, the monitoring unit 405 notifies the system administrator that connection to the management server 103 cannot be established, for example by displaying a message on a management screen (not shown) of the monitoring device 102 (step S907). Note that the method of notifying the administrator is not particularly limited, and may be an email notification, etc.

As described above, in this embodiment, the normality/abnormality of the proxy server 404 is determined based on whether communication is possible. Therefore, according to this embodiment, even if the proxy server 404 has an internal malfunction, the state can be automatically detected.

[Fourth embodiment]
The monitoring apparatus 102 of this embodiment, like the second embodiment, has a device management unit 406 for managing the image forming apparatus 101 (see FIG. 6). However, as described later, the contents of the processing performed by the device management unit 406 are different from those in the second embodiment (see FIG. 11).

Other configurations of the monitoring device 102, the configurations of the image forming device 10 and the management server 103, and the overall network configuration are substantially the same as those in the first embodiment (see FIGS. 1 to 4).
In each of the above embodiments, it is periodically checked whether the operating status of the proxy server 404 is normal.

In response to this, in this embodiment, a control is provided to prevent the proxy server 404 from entering a state in which anomalies are likely to occur.
For example, when the amount of communication data between the image forming apparatus 101 and the management server 103 increases, the load on the proxy server 404 increases, making it more likely that an abnormality will occur.

<Operation of monitoring device>
FIG. 11 is a flowchart illustrating an example of the operation of the monitoring device 102 according to this embodiment.
As in the above-described embodiments, in this embodiment, the monitoring unit 405 monitors the operation state of the proxy server 404 at each predetermined monitoring timing. Therefore, the monitoring unit 405 waits until the time reaches the monitoring timing (step S1001). When the time reaches the monitoring timing, the process proceeds to step S1002. As in the above-described embodiments, the monitoring timing is not limited.

In step S1002, the monitoring unit 405 checks the load of the proxy server 404. The load of the proxy server 404 can be quantified based on information such as the CPU usage rate, memory usage rate, and number of connections per unit time of the proxy server 404. Then, the numerical value is compared with a predetermined reference value to determine whether the load is high or not. Note that only a part of this information may be used as the information used to quantify the load, or other information may be used instead of or in addition to this information.

If the load on the proxy server 404 is lower than the reference value in step S1002, the monitoring unit 405 ends the process.
On the other hand, if the load on the proxy server 404 exceeds the reference value in step S1002, the device management unit 406 of the monitoring apparatus 102 instructs the self-monitoring unit 604 of the image forming apparatus 101 to change the settings of the monitoring information.

For example, if the self-monitoring unit 604 is changed to monitor only information with a high degree of urgency, the amount of data of the operation information sent to the management server 103 (i.e., the amount of data relayed by the proxy server 404) will decrease, and the load on the proxy server 404 will be reduced. Information with a high degree of urgency is, for example, information regarding errors in the image forming device 101 and information regarding the replenishment of consumables. For other information, i.e., information with a low degree of urgency, the acquisition unit 401 of the monitoring device 102 may, for example, periodically poll and acquire the information, and transmit it to the management server 103.

As described above, according to this embodiment, the amount of data sent from the self-monitoring unit 604 is suppressed depending on the load on the proxy server 404, making it possible to reduce abnormalities caused by an excessive amount of communication data on the proxy server 404.

Note that the method of reducing the amount of data transmitted from the self-monitoring unit 604 is not limited to the method of this embodiment. For example, for some of the multiple image forming devices 101, the data transmitted from the self-monitoring unit 604 may be received by the monitoring device 102 functioning as a Web server, rather than passing through the proxy server 404. This makes it possible to reduce the amount of data handled by the proxy server 404.
