Troubleshooting

Testing Monitor Requests

Testing Monitor Requests

To test that events are being sent, use the INITIAL option available with conditional notification when creating a monitoring request. This option sends an initial event that you can examine 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 Disk Monitor Requests

Configuring the INITIAL option may be enough. However, if you want to test that events are sent when a disk fails, you may want to detach the bus or power down the storage devices and see if events are sent to the proper application, or if MC/ServiceGuard fails over the appropriate package. This is only recommended on clusters that are off-line, and not being accessed by users.

To test /vg/vgName/lv/copies and /vg/vgName/lv/status, use the vgchange command to deactivate and activate the volume group and see if the proper alerts were sent.

Testing Cluster Monitor Requests

Use the cmviewcl -vcommand 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 user and system load. The EMS system resource monitor should return the sam values as this command.
