Nagios Plugins

 • Plugins are compiled executables or scripts(Perl or non-Perl) that extends Nagios functionality to monitor servers and hosts

• Nagios will execute a Plugin to check the status of a service or host

• Nagios can be compiled with support for an embedded Perl interpreter to execute Perl plugins

• Without it, Nagios executes Perl and non-Perl plugins by forking and executing the plugins as an external command


Nagios Remote Plugin Executor (NRPE)

• NRPE allows you to remotely execute Nagios plugins on other Linux/Unix machines. This allows you to monitor remote machine metrics such as disk usage, CPU load etc

• It can communicate with some of the Windows agent addons, so you can execute scripts and check metrics on remote Windows machines as well


Nagios Remote Data Processor

• Nagios Remote Data Processor (NRDP) is an agent which allows flexible data transport

• It uses standard protocols such as: https:// , XML

If your team do it right, then they would take in just the right amount of work into ...
