Chapter 4 Modifying IPM Components

Setting New IPM Server Process Timeout Values

By default, the variable definitions are commented out in the file:

# Max value is 60 (seconds), default is 5 (seconds), min is 1 (seconds)

#set IPM_SNMP_TIMEOUT=5

# Max value is 5, default is 3, min is 1

#set IPM_SNMP_RETRIES=3

# Max value is 60, default is 5, min is 1

#set IPM_SNMP_TIMEOUT_INCREMENT=5

Step 3 To change a variable definition, remove the comment markers (#) from the definition and change the

settings. For example, to change the timeout value to 10 seconds, change the following lines in the file:

# Max value is 60, default is 5, min is 1

set IPM_SNMP_TIMEOUT=10

Step 4 Save your changes and close the file.

Step 5 Log in as the administrator.

Step 6 Restart the IPM servers by entering:

cd c:\Program Files\Internetwork Performance Monitor\server\bin

ipm restart

When the IPM servers start up, they discover the variables and use the new timeout and retry values.

Setting New IPM Server Process Timeout Values

The default timeout value for data collection servers and configuration servers is 120 seconds. This value

accommodates the longer startup times encountered when you have a large number of collectors.

However, if you have configured more than 2000 collectors on a single IPM server, you might need to

increase this timeout value. These timeout values control internal IPM timing; they do not affect

communication with source routers.

For each group of 500 collectors above 2000, add 30 seconds to the default timeout value of 120 seconds

for both the data collection server and configuration server. For example, for 1500 collectors change the

timeout value to 150 seconds for both servers. If you do not make this change, the Process Manager

might timeout while waiting for the data collection server to start up, thus preventing initialization of the

configuration server.

To increase the timeout value, allowing sufficient time for the data collection server process to start, use

one of the following procedures:

• Setting Server Timeout Values in Solaris

• Setting Server Timeout Values in Windows
