NRPE IMAP

NRPE IMAP Profile

This profile monitors an IMAP 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.

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.

Implementation

Command Parameters

Command parameters are in the Configuration Services section with the following names and default values.

IMAPS_Alive

Check for connect() TCP on port number 993 of $HOSTADDRESS$

IMAPS_Server

Uses check_imap plugin with the --S (SSL) switch to connect to port 993 of $HOSTADDRESS$ and search for ‘[* OK]’ in the IMAP server output.
Default warning threshold is a 4 second response time.
$ARG1$ - Warning seconds
Default critical threshold is a 6 second response time.
$ARG2$ - Critical seconds

IMAP_Alive

Check for connect() TCP on port number 143 of $HOSTADDRESS$

IMAP_Server

Uses check_imap plugin to connect to port 143 of $HOSTADDRESS$ and search for ‘[* OK]’ in the IMAP server output.
Default warning threshold is a 4 second response time.
$ARG1$ - Warning seconds
Default critical threshold is a 6 second response time.
$ARG2$ - Critical seconds

nrpe_cpu

Uses check_nrpe plugin to connect to NRPE on $HOSTADDRESS$ and execute the wmi_cpu command as defined in the nrpe.cfg.
Default warning threshold is 80% CPU usage
ARG1$ - Warning percentage
Default critical threshold is 90% CPU usage
$ARG2$ - Critical percentage

nrpe_disk_C

Uses check_nrpe plugin to connect to NRPE on $HOSTADDRESS$ and execute the wmi_disk command as defined in the nrpe.cfg.
Default drive is set for C: disk
$ARG1$ - Drive letter
Default warning threshold is 80% usage
$ARG2$ - Warning percentage
Default critical threshold is 90% usage
$ARG3$ - Critical percentage

nrpe_mem

Uses check_nrpe plugin to connect to NRPE on $HOSTADDRESS$ and execute the wmi_mem command as defined in the nrpe.cfg.
Default warning threshold is greater than 80% of Memory usage
$ARG1$ - Warning percentage
Default critical threshold is greater than 90% of Memory usage
$ARG2$ - Critical percentage

nrpe_process_<PROCESSNAME>

nrpe_process_Alerter

nrpe_process_Eventlog

nrpe_process_IMAP4Svc

nrpe_process_MSDTC

nrpe_process_TermService

Where PROCESSNAME is equal to the name of a process which should be running on the NRPE host. Sometimes processes will have spaces in there names. In this case an underscore (_) is used in place of any spaces in the service name.
Uses check_nrpe plugin to connect to NRPE on $HOSTADDRESS$ and execute the check_service2_vb command as defined in the nrpe.cfg.
OK if service is running
CRITICAL is service is stopped or not installed.

Performance Graphing Parameters

The following parameters are used to generate performance charts. These parameters are set using the Configuration>Performance tool in GroundWork Monitor.
