I am remotely monitoring a Oracle database instance. How do I monitor multiple listeners for just one Oracle database instance?
Component: oracle probe
You can accomplish the monitoring of multiple Oracle listeners by creating a user-defined scan for each listener. The .sql script for the user-defined scan will include the command from the SQL*NET V STATUS scan which is:
ps -ef | grep tnslsnr | grep -v grep | wc -l
The grep in the above command will be modified to grep for the specific listener's name. After the user-defined scan is setup, you can then create a genlimit alarm based on the user-defined scan created.
