10.4.4 Distributed Monitoring Usage Scenarios

Below are a number of distributed monitoring Nagios scenarios:

Local office

In this scenario, the console server is set up to monitor each managed device’s console. Configure it to make a number of checks, either actively at the Nagios server's request, or passively at preset intervals, and submit the results to the Nagios server in a batch.

You can augment the console server at the local office site by one or more Intelligent Power Distribution Units (IPDUs) to remotely control the power supply to the managed devices.

Remote site

In this scenario, configure the console server NRPE server or NSCA client to actively check configured services and upload the checks to the Nagios server that’s waiting passively. You can also configure it to service NRPE commands to perform checks on demand.

In this situation, the console server will perform checks based on both serial and network access.
