Data collection from Windows Performance Counters with NSClient++
From OpenNMS

Topic
This example describes how you can collect Win perf-data with OpenNMS and NSClient++.
The gathered data can be displayed in a graphical report with OpenNMS.

OpenNMS Configuration
capsd-configuration.xml
Make the following entry in OpenNMS capsd-configuration.xml to discover the service. In current releases this configuration is already done and shipped by default.
<protocol-plugin protocol="NSClientpp"
class-name="org.opennms.netmgt.capsd.plugins.NsclientPlugin" scan="on"
user-defined="false">
<property key="banner" value="*" />
<property key="port" value="12489" />
<property key="timeout" value="3000" />
<property key="retry" value="1" />
</protocol-plugin>
poller-configuration.xml
Define the Service in the OpenNMS poller-configuration.xml (shipped by default in current releases)
<service name="NSClientpp" interval="300000" user-defined="false" status="on">
<parameter key="retry" value="2"/>
<parameter key="port" value="12489"/>
<parameter key="timeout" value="3000"/>
</service>
nsclient-config.xml
In the nsclient-config.xml you have to define on which port NSClient++ can be
polled by OpenNMS.
NSClient++ is using "12489" as the default port.
<?xml version="1.0"?>
<nsclient-config port="12489" retry="3" timeout="3000">
</nsclient-config>
collectd-configuration.xml
In the collectd-configuration we have to define a further package of the name "example2" which contains the filter and service definition. The ip-address in the 'specific' tag is the Win host where NSClient++ is running.
<?xml version="1.0"?>
<?castor class-name="org.opennms.netmgt.collectd.CollectdConfiguration"?>
<collectd-configuration
threads="50">
<package name="example1">
<filter>IPADDR != '0.0.0.0'</filter>
<include-range begin="1.1.1.1" end="254.254.254.254"/>
<service name="SNMP" interval="300000" user-defined="false" status="on">
<parameter key="collection" value="default"/>
</service>
</package>
<package name="example2">
<filter>IPADDR IPLIKE *.*.*.*</filter>
<specific>192.168.71.111</specific>
<service name="NSClientpp" interval="150000" user-defined="false" status="on">
<parameter key="nsclient-collection" value="default"/>
<parameter key="port" value="12489"/>
<parameter key="retry" value="3"/>
<parameter key="timeout" value="3000"/>
</service>
</package>
<collector service="SNMP" class-name="org.opennms.netmgt.collectd.SnmpCollector"/>
<collector service="NSClientpp" class-name="org.opennms.netmgt.collectd.NSClientCollector"/>
</collectd-configuration>
nsclient-datacollection-config.xml
In this example we want to collect data from the performance counter "\LogicalDisk(C:)\% Free Space" on the Win host where NSClient++ is running.
<?xml version="1.0"?>
<nsclient-datacollection-config rrdRepository="/opt/opennms/share/rrd/snmp/">
<nsclient-collection name="default">
<rrd step="300">
<rra>RRA:AVERAGE:0.5:1:8928</rra>
<rra>RRA:AVERAGE:0.5:12:8784</rra>
<rra>RRA:MIN:0.5:12:8784</rra>
<rra>RRA:MAX:0.5:12:8784</rra>
</rrd>
<wpms>
<!-- A group for collecting processor stats.
Check the keyvalue "\LogicalDisk(C:)\% Free Space"
Check every recheckInterval milliseconds (300000 = 1hr) -->
<wpm name="LDCFreeSpace" keyvalue="\LogicalDisk(C:)\% Free Space" recheckInterval="300000">
<!-- Collect these attributes. Name is the name to pass to NSClient.
Alias is the local name for the RRD file
Type is used to convert values around
maxval/minval are optional-->
<attrib name="\LogicalDisk(C:)\% Free Space" alias="LD_C_FreeSpace" type="Gauge"/>
</wpm>
</wpms>
</nsclient-collection>
</nsclient-datacollection-config>
NSClient++ Configuration
You can list all perf-counters you can collect data from with the following command:
C:\> NSClient++ CheckSystem listpdh
[modules]
;# NSCLIENT++ MODULES
;# A list with DLLs to load at startup.
; You will need to enable some of these for NSClient++ to work.
