The process of the present invention is illustrated in clear detail below by means of specific examples, which are only intended to illustrate the invention and are not intended to limit the scope of the process of the invention.
Example 1
Fig. 3 is a flowchart of a method according to a first embodiment of the present invention, as shown in fig. 3, including:
and step 300, performing matching filtering on the generated log and the preset alarm level to obtain a part reaching the preset alarm level in the generated log.
Specifically, the method comprises the steps of acquiring a network address of a log server from a forwarding plane;
when the log server is directly connected with the router, a destination address sent by the log is obtained as a next route hop; when the log server is not directly connected with the router, inquiring a routing table to obtain a next route hop;
taking the acquired network address and the next routing hop of the log server as query key values; and inquiring the forwarding information from the cache by the inquiry key value.
It should be noted that, when the forwarding information of the forwarding plane is updated, new forwarding information is added, or the forwarding information is deleted, first, corresponding processing needs to be performed on the forwarding information in the cache, so as to perform corresponding adjustment on transmission of the generated log. The specific adjustment procedure is within the common general knowledge of a person skilled in the art.
The query key value also comprises quintuple information of an outgoing interface of the router;

the virtual interface is at least one of the following interfaces: a link aggregation group (Smartgroup) interface, a super virtual local area network (Supervlan) interface, a multi-link point-to-point protocol (MPPP), and a Posgroup interface.
When the output interface is a virtual interface, the five-tuple information of the output interface of the router is as follows:
and inquiring the interface port state information to select an activated physical interface, and taking the information of the selected activated physical interface and the virtual interface as quintuple information of the router output interface.
And step 302, sending the part of the generated log reaching the preset alarm level to one or more log servers configured in advance according to the inquired forwarding information.
The forwarding information at least includes: ESH, switching heads (SAIH and ITMH), and NPH; the forwarding information is generally combined to generate a cookie, wherein two-layer forwarding is carried out based on ESH, and the generated log is sent to an SA chip; the SA chip will be exchanged to TM chip based on SAIH, strip ESH and SAIH; the TM chip sends the generated log to a Network Processor (NP) based on the ITMH; the NP chip sends the TM to the physical panel port based on NPH.
And step 303, sending the part of the generated log reaching the preset alarm level to a log server corresponding to the address of the log server in a SOCKET (SOCKET) mode. Here, when log transmission is performed in the SOCKET manner, a forwarding message still needs to be acquired from the forwarding plane. After one-time transmission, the subsequent forwarding information is transmitted to the exchange; in this embodiment, the query failure means that no corresponding cookie can be found in the cache.
In this embodiment, only when the generated log reaches the preset alarm level, the forwarding message in the cache is queried and acquired, and the log is transmitted. The flexible log transmission method can quickly transmit the log through the quick forwarding channel and can also transmit the generated log in a SOCKET mode. The transmission of the generated logs is supported under the conditions of IPV4 and IPV6 addresses, virtual interfaces, real interfaces, direct connection and non-direct connection, and the transmission efficiency of the generated logs is effectively improved by caching the forwarding information; the transmission speed is ensured by the fast transmission channel.
