To test that events are being sent, use the INITIAL option
available with conditional notification when creating a monitoring
request. This option sends notification on startup. Examine it to
make sure your request is properly configured and showing up in
the correct system management tool.
An alternative is to use the "At each interval" notification
to test that events are being sent in the correct system management
tool. Once you establish that events are being sent properly, you
can modify the request.
Testing Cluster Monitor Requests |
 |
Use the cmviewcl -v command to display detailed information about the current
status of the cluster and packages on the cluster. The EMS cluster
monitor should return the same values as this command.
Testing Network Monitor Requests |
|
If you want to test whether events are sent in case of network
failure, use the /usr/bin/ifconfig LANname down command to bring a card down, and examine the event to
make sure it shows up in the correct system management tool.
Testing System Resource Monitor Requests |
|
Use the uptime command to verify the number of users and the system load.
The EMS system resource monitor should return the same values that
this command does.
Making Sure Monitors are Running |
|
Monitor daemons automatically start when you create a monitoring request.
Because monitoring is designed to work in a high-availability environment,
monitors are written to automatically restart if anything causes
them to fail.
A daemon called p_client restarts all appropriate monitors using the monitor
restart interval defined in /etc/opt/resmon/config. Therefore, a monitor cannot be permanently stopped
or started by a human.
Because the monitors are persistent, monitoring requests are
kept when you install a new monitor or update an existing monitor.
If a condition, such as "status > 3" is
being monitored for a resources that has a range of 1-7, and new
version of monitor is installed that supports a new status value,
such as "8", you may start seeing notifications
for "status=8".
