NRPE POP3 Profile

This profile monitors a POP3 server running on a Windows server using Nagios Remote Plugin Executor (NRPE). NRPE is used by the Nagios server to communicate with the Windows server.

Services Configuration

Service - Definitions in Monarch are stored under this name.
Command Line - Service command name with arguments to be passed to the plugin.
Plugin Command Line - Plugin script called by Nagios for this Service.

Extended Info - The Extended Service Info definition, typically used for generating graphs.

Command lines displayed below are intended to be single line commands.

Service	Command Line	Plugin Command Line	Extended Info
tcp_pop3s	check_pop3s!3!5	$USER1$/check_pop -t 60 -H $HOSTADDRESS$ -w "$ARG1$" -c "$ARG2$" -S	number_graph
tcp_pop3	check_pop3!3!5	$USER1$/check_pop -t 60 -H $HOSTADDRESS$ -w "$ARG1$" -c "$ARG2$" -e "OK"	number_graph

Installation

GroundWork Monitor includes many monitoring profiles for a variety of devices, systems and applications. Profiles already imported on a new GroundWork installation include Service Ping, SNMP Network, and SSH UNIX. The GroundWork Monitor Configuration tool is used to import updated Profiles and Profiles that require additional setup; the Profile XML file and its companion Performance Configuration definition file. Services can also be imported in addition to Service Profiles in the Profile Importer. The import process is documented under GROUNDWORK PROFILES > How to import profiles.
