Monitoring Linux systems using SSH

Hi,

Currently starting the implementation of Logicmonitor in our organization, replacing an old agent based monitoring tool. Probably one of the main reasons to select LM has been the agent-less monitoring capabilities.

SNMP based linux monitoring is not an option for us, neither installing LM collectors in each monitored server.

So with current SSH based Linux datasources we miss important required capabilities:

- Linux text log monitoring: Basically, we need to be able to monitor specific log files in a target server for the appearance of specific error patterns on them, and raise an alert in case any of this error occurs. The rule to trigger the alarm must manage the triggering of the alarm depending on the recurrence of the errors and probably other rules. The datasource should be able to manage checkpoints in order to be aware what was the last log line read ensuring that always read only new content in monitored files.

- OS process monitoring: we need to be able to monitor the presence of OS processes and if the number of processes instances required are in execution and probably other rules.

Thanks.

You would accomplish this via a custom EventSource.

You can do this with a custom Groovy based Datasource making use of the Expect library built into the collector.
