Administering the IGS

Use

You can monitor the IGS in two ways:

·         Using the Web Interface

http://(hostname):(port)

hostname = The name of the machine where the Igs is installed, for example P12345

port = The port of the http listener. You can find this in the IGS configuration file.

·        Using CCMS

You can use an SAP system (Basis Release 6.10 and later) to monitor the IGS. The CCMS transaction rz20 is used as the monitoring tool. You can find more information on CCMS in our Knowledge Warehouse documentation.

CCMS gives the administrator an overview of the current IGS configuration. The portwatchers available and their associated interpreters are displayed in a hierarchy. CCMS also displays various performance values for the relevant IGS components.

The performance values of the available components are updated automatically with the result that bottlenecks can be located and removed quickly.

CCMS

Uptime
The "uptime" is a CCMS performance measurement. It specifies the number of seconds the portwatcher has already been running for.

Data volume in (min)
This specifies the smallest amount of data sent in a call from the multiplexer to the portwatcher and its interpreter. (Different calls typically involve sending different amounts of data.)

Data volume in (max)
This specifies the largest amount of data sent in a call from the multiplexer to the portwatcher and its interpreter. (Different calls typically involve sending different amounts of data.)

Data volume in (avg)
This specifies the average amount of data sent in a call from the multiplexer to the portwatcher and its interpreter. (Different calls typically involve sending different amounts of data.)

Data volume out (min)
This specifies the smallest amount of data returned after a call from the multiplexer to the portwatcher and its interpreter. (Different calls typically result in different amounts of data being returned.)

Data volume out (max)
This specifies the largest amount of data returned after a call from the multiplexer to the portwatcher and its interpreter. (Different calls typically result in different amounts of data being returned.)

Data volume out (avg)
This specifies the average amount of data returned after a call from the multiplexer to the portwatcher and its interpreter. (Different calls typically result in different amounts of data being returned.)

Duration (min)
This specifies the minimum duration required for generating a graphic / for an interpreter task.
The duration is expressed in milliseconds.

Duration (max)
This specifies the maximum duration required for generating a graphic / for an interpreter task. The duration is expressed in milliseconds.

Duration (avg)
This specifies the average duration required for generating a graphic / for an interpreter task. The duration is expressed in milliseconds.

Calls
This shows the number of calls from the multiplexer to the portwatcher.

Activities

CCMS

In rz20 you can find the IGS as the Internet Graphics Server in the monitor set SAP CCMS Monitors for Optional Components.

When you double-click on this entry a hierarchy with performance values should be displayed. If no hierarchy is displayed, even though the IGS is running, call transaction se38 and execute the program graphics_igs_admin. Choose Environment  ® Switch on CCMS to activate the IGS display in rz20.
