Nagios - monitoring and notification
Nagios (
http://www.nagios.org
)
is an open source monitoring and notification utility. It en-
ables users to monitor various resources, such as CPU, memory, disk usage, network status,
reachability, HTTP status, testing of web page rendering, and various checks using Nagios-
compatible sensors. There is a giant list of Nagios plugins that covers the monitoring of al-
most all popular services and software. The best thing with Nagios is its plugin architec-
ture. You can write a simple plugin for custom resource monitoring. Thus, effectively, if
you can measure a state, you can monitor its source in Nagios. This section will discuss,
very briefly, Nagios setup and how it can be enabled to monitor system resources and Cas-
sandra.
