Description: |
This addon is designed to provide a way for executing plugins on a remote host. The check_nrpe plugin runs on the Nagios host and is used to send plugin execution requests to the nrpe agent on the remote host. The nrpe agent will then run an appropriate plugins on the remote host and return the plugin output and return code to the check_nrpe plugin on the Nagios host. The check_nrpe plugin then passes the remote plugin's output and return code back to Nagios as if it were its own. This allows for a rather transparent method of executing plugins on remote hosts. The nrpe agent can either be run as a standalone daemon or as a service under inetd. |

Description: |
This addon allows you to send passive service check results from remote hosts to a central monitoring host that runs Nagios. The client can be used as a standalone program or can be integrated with remote Nagios servers that run an ocsp command to setup a distributed monitoring environment. Communication between the client and daemon can be encrypted via various algorithms (DES, 3DES, CAST, xTEA, Twofish, LOKI97, RJINDAEL, SERPENT, GOST, SAFER/SAFER+, etc.) if you have the mcrypt libraries installed on your systems. |
