Resolving monitoring server problems
Monitoring server problems are caused by a monitoring server that is not started
or connectivity that is lost either between servers or between servers and agents.
You can restart the Tivoli Enterprise Monitoring Server, and you can also run the
ITMSUPER Topology tool to get more information.
About this task
To resolve monitoring server problems, you perform diagnostic and corrective
actions. These actions include running tools, such as the Topology or Connectivity
tool and correcting communication failures in logs.
Procedure
Diagnostic and corrective actions
1.
If you are an administrator, restart the monitoring server. Otherwise, notify an
administrator and wait for the monitoring server to be restarted.
2.
Running the following ITMSUPER tools might also provide more information:
v
Topology tool
v
Connectivity tool
v
Tivoli Enterprise Monitoring Server analysis tool
v
Tivoli Enterprise Portal Server
3.
Check the portal server logs for messages indicating communication failures to
the monitoring server.
4.
Check the monitoring server logs for messages indicating communication
failures to the remote monitoring servers or to monitoring agents.
5.
Correct the communication failures indicated in the logs.
Resolving monitoring agent problems
If the monitoring agent is running but data is not being returned or if you receive
an error message from an agent log, such as
Endpoint unresponsive
, verify that the
agent is connected and online. You can also verify that application support has
been installed correctly.
About this task
To resolve monitoring agent problems, you perform diagnostic and corrective
actions. These actions include verifying that the agent is running and that
application support has been installed correctly. For information on monitoring
agents on z/OS
®
see each product's
Problem Determination Guide
.
Procedure
Diagnostic and corrective actions
1.
Verify that the agent is connected. Check the monitoring server log for
messages similar to
Remote node <SYS:MQIRA> is ON-LINE
.
2.
If the agent is online, check to see whether subnodes are online in the agent
log. For example:
KMQMI171I Node JSG1:SYS:MQESA is online
.
