However, Nagios can be configured to send notifications for unreachable hosts if you want it to. The second way Nagios can track dependencies between hosts is with dependency definitions. These definitions work for both hosts and services and are used to track more subtle 17 The Host and Service Paradigm dependency relationships between different hosts, or services running on different hosts. A good example of this type of dependency tracking is a web proxy. 1, the firewalls are configured such that only one host on the secure network is allowed to connect to the Web server’s port 80.
The daemon does so, providing the client output and an exit code, which the client, in turn, passes to Nagios. Any program can be securely executed on the remote server by NRPE, if it’s defined in the daemon’s configuration file. X509 certificates can be used to authenticate the client to the daemon and encrypt the transmission. NRPE is completely cross platform, so it can handle remote execution for Windows and UNIX clients of all flavors. ” Scheduling Now that you have a good understanding of what plugins are and how they work, you need to know how Nagios goes about scheduling them.
3. Minimize the number of dependencies between the monitoring system and the most critical systems.
