Hi @xpertech,

There are a a few options available for monitoring logs.

1. You can use the check_log plugin that is part of the Nagios Plugins Project. This plugin scans a log file on the server and reports any new matches to the query provided.

Example:

Code: Select all

./check_log -F /var/log/messages -O /var/log/messages_old -q 'Error'

See: Log Checks on the Nagios Knowledgebase

2. There are quite few plugins on the Nagios Exchange for monitoring logs such as check_logfiles with additional features.

Lastly, we also have another product, Nagios Log Server, that is specifically designed for log management and analysis.

Let me know if you have any specific questions.

Does the NagiosXI default plugin Check_Log need to install both NRPE agent and Check_Log plugin on the remote monitored server? is there a steps document of install check_log?

Hello @xpertech,

The plugin check_log is part of the official Nagios Plugins, these are typically installed along with NRPE on the remote host.

To install NRPE along with the Nagios Plugins, the easiet method is to use the install script documented here:

NRPE - How to install NRPE

For instructions on installing just the Nagios Plugins, please see:

Let me know if you have any other questions.
