Observer

The Application Observer provides a convenient web interface to view node status, network activity, and running processes in the node built with Ergo Framework. Additionally, it allows you to inspect the internal state of processes or meta-processes. The application is can also be used as a standalone tool Observer. For more details, see the section Inspecting With Observer. You can add the Observer application to your node during startup by including it in the node's startup options:

import (
	"ergo.services/ergo"
	"ergo.services/application/observer"
	"ergo.services/ergo/gen"
)

func main() {
	opt := gen.NodeOptions{
		Applications: []gen.ApplicationBehavior {
			observer.CreateApp(observer.Options{}),
		}
	}
	node, err := ergo.StartNode("example@localhost", opt)
	if err != nil {
		panic(err)
	}
	node.Wait()
}

The function observer.CreateApp takes observer.Options as an argument, allowing you to configure the Observer application. You can set:

• Port: The port number for the web server (default: 9911 if not specified).

• Host: The interface name (default: localhost).

• LogLevel: The logging level for the Observer application (useful for debugging). The default is gen.LogLevelInfo
