When using the RPM monitor scripts, it is quite useful to look at the script logs. These logs record events such as probe

failures, enabling/disabling of the backup interface, etc. Using the configuration shown in the last example, the logs can

be viewed with the “show log rpm-monitor” command.

# run show log rpm-monitor

Jan 22 05:15:48 SRX210-Home cscript: rpm-monitor: Triggered by ping_test_up test

server1 owner rpm-monitor-probes

Jan 22 05:15:48 SRX210-Home cscript: rpm-monitor: RPM probe up agged, but there

is nothing to do with the logical interfaces

server1 owner rpm-monitor-probes

Jan 22 05:16:59 SRX210-Home cscript: rpm-monitor: RPM probe up agged, but there

is nothing to do with the routes

The result of the RPM probes can be viewed with the following command:

pato@SRX210-Home# run show services rpm history-results
