Install and Configure Nagios to Administer a Networking System
Install and Configure Nagios to Administer a Networking System
Nagios is a very powerful platform because it is easy to extend. The previous chapters talked about check command plugins and how they can be used to check any host or service that your company might be using. Another 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 benefi t from powerful notifi cation systems as well as dependency tracking. This mechanism can also be used to receive failure notifi cations from other services or machines—for example, SNMP (Simple Network Management Protocol) traps. This is described in more detail in Chapter 9. Nagios also offers a tool for sending passive check results for hosts and services over a network. It is called NSCA (Nagios Service Check Acceptor). It can be used to send results from one Nagios instance to another. It can also be used by third-party applications running on different machines to send passive check results to a central Nagios server. This mechanism includes password protection, along with encryption, to prevent injection of false results in to Nagios. In this way, NSCA communication sent over Internet is more secure.
