HostResourceSwRunMonitor This monitor test the running state of one or more processes. It does this via SNMP by inspecting the hrSwRunTable of the HOST-RESOURCES-MIB. The test is done by matching a given process as hrSwRunName against the numeric value of the hrSwRunState. This monitor uses SNMP to accomplish its work. Therefore systems against which it is to be used must have an SNMP agent installed and configured. Furthermore, the SNMP agent on the system must support the HOST-RESOURCES-MIB. Most modern SNMP agents, including most distributions of the Net-SNMP agent and the SNMP service that ships with Microsoft Windows, support this MIB. Out-of-box support for HOST-RESOURCES-MIB among commercial Unix operating systems may be somewhat spotty. Monitor Facts Class Name org.opennms.netmgt.poller.monitors.HostResourceSwRunMonitor Remote Enabled false Configuration and Use Table 1. Monitor specific parameters for the HostResourceSwRunMonitor Parameter Description Required Default value port The port of the SNMP agent of the server to test. optional from snmp-config.xml service-name The name of the process to be monitored. This parameter’s value is case-sensitive and is evaluated as an exact match. required - match-all If the process name appears multiple times in the hrSwRunTable, and this parameter is set to true, then all instances of the named process must match the value specified for run-level. optional false run-level The maximum allowable value of hrSWRunStatus among running(1), runnable(2) = waiting for resource notRunnable(3) = loaded but waiting for event invalid(4) = not loaded optional 2 service-name-oid The numeric object identifier (OID) from which process names are queried. Defaults to hrSwRunName and should never be changed under normal circumstances. That said, changing it to hrSwRunParameters (.1.3.6.1.2.1.25.4.2.1.5) is often helpful when dealing with processes running under Java Virtual Machines which all have the same process name java. optional .1.3.6.1.2.1.25.4.2.1.2 service-status-oid The numeric object identifier (OID) from which run status is queried. Defaults to hrSwRunStatus and should never be changed under normal circumstances. optional .1.3.6.1.2.1.25.4.2.1.7 This monitor implements the Common Configuration Parameters. Examples The following example shows how to monitor the process called httpd running on a server using this monitor. The configuration in poller-configuration.xml has to be defined as the following: <service name="Process-httpd" interval="300000" user-defined="false" status="on"> <parameter key="retry" value="3"/> <parameter key="timeout" value="3000"/> <parameter key="service-name" value="httpd"/>(1) <parameter key="run-level" value="3"/>(2) <parameter key="match-all" value="true"/>(3) </service> <monitor service="Process-httpd" class-name="org.opennms.netmgt.poller.monitors.HostResourceSwRunMonitor"/> 1 Name of the process on the system 2 Test the state if the process is in a valid state, i.e. have a run-level no higher than notRunnable(3) 3 If the httpd process runs multiple times the test is done for each instance of the process.
