WMI IMAP

WMI Internet Message Access Protocol (IMAP) Profile

This profile monitors IMAP services on a Windows server using Windows Management Instrumentation (WMI). Nagios Remote Plugin Executor (NRPE) is used by the Nagios server to communicate with the WMI proxy server. This proxy server queries the monitored Windows server for measurements and status using WMI.

Additionally, you may want to refer to the WMI documentation. This project consists of a collection of script monitors (.vbs for starters) that use the Microsoft .Net Framework and WMI to retrieve performance data from remote Windows hosts without the need for agents on the remote hosts.

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 - 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_imap	check_imap!3!5	$USER1$/check_imap -t 60 -H $HOSTADDRESS$ -w "$ARG1$" -c "$ARG2$" -p 143	number_graph
tcp_imaps	check_imaps!3!5	$USER1$/check_imap -t 60 -H $HOSTADDRESS$ -w "$ARG1$" -c "$ARG2$" -p 993 -S	number_graph
wmi_service_IMAP4Svc	check_wmi_service!IMAP4Svc	$USER1$/check_nrpe -H $USER21$ -t 60 -c get_service -a "$HOSTADDRESS$" "$ARG1$"	percent_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.

Implementation

This section contains detail settings used by this Profile. These parameters can be altered with the Configuration tool.

Command Parameters

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

tcp_imap

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 3 second response time.
$ARG1$ - Warning seconds
Default critical threshold is a 5 second response time.
$ARG2$ - Critical seconds

tcp_imaps

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 3 second response time.
$ARG1$ - Warning seconds
Default critical threshold is a 5 second response time.
$ARG2$ - Critical seconds

wmi_service

Uses check_nrpe plugin to connect to NRPE on $USER21$ and execute the get_service command as defined in the nrpe.cfg against the host $HOSTADDRESS$.
$ARG1$ - Service Name (not Display Name!)
OK if service is running
CRITICAL is service is stopped.
UNKNOWN is service is 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.
