Monitoring the ICM with the ICM Monitor (SAP Library - Architecture of the SAP Web Application Server)

Monitoring the ICM with the ICM Monitor

Use

You can use this transaction (SMICM) to monitor and administrate the Internet Communication Manager, which sends and receives requests to and from the Internet.

Prerequisites

The ICM is running on the server. In transaction SM51, you can see the work process types provided on the server and the entry ICM.

Functions

In the initial screen you can see a list of the worker threads from the activities of the individual threads.

This graphic is explained in the accompanying text

The fields in the display have the following meaning:

Field	Meaning
No.	Thread number: The threads that are available for processing (receiving or sending) requests are numbered by the ICM (like the work processes by the dispatcher).
Thread ID	The thread ID that is assigned by the operating system (analogous to the PID for processes).
Number	The number of requests that were processed by this thread.
Status	The current status of the thread. The following values are possible: Free: The thread is waiting for a request. Running: The thread is processing a request. In this case, you can display detailed information by double-clicking on the line. Column Processed Request also displays more information.
Processed request	The type of request that the thread is currently processing. Possible values are:
	Blank field	The thread is not currently doing anything
	Administration	Action that is triggered by Transaction SMICM or program icmon, such as the list display. This means that at least one thread always displays administration when you call SMICM.
	Read request	Reads the request (server)
	Read response	Reads the response (client)
	Write request	Writes the request (client)
	Write response	Writes the response (server)
	Open connection	Sets up the connection to a server
	Close connection	Closes the connection to a partner
	Accept connection	Accepts the connection from a client
	Time-dependent action	Executes time-dependent (periodically scheduled) events
	Execute shutdown	Ends ICM
	Wait for data	Waits for data from the network or from the application server (SAP Web dispatcher)
	Wait for response (SERV)	Waits for a response from the application server (SAP Web AS is a server with active connections)
	Wait for response (CLNT)	Waits for a request from the application server (SAP Web AS is a server with active connections)
