Passive Checks and NSCA (Nagios Service Check Acceptor)
Author: JT Smith
Nagios is a very powerful platform because it is easy to extend. A great feature that Nagios offers is the ability for third-party software or other Nagios instances to report information on the status of services or hosts. This way, Nagios does not need to schedule and run checks by itself, but other applications can report information as it is available to them. This means that your applications can send problem reports directly to Nagios, instead of just logging them. In this way, your applications can benefit from powerful notification systems as well as dependency tracking. In this article we will see how this mechanism can also be used to receive failure notifications from other services or machinesÃ¢â¬âfor example, SNMP traps.
