Lars and all,

Got it sorted out for wmi disk thresholding:

My mistakes were in the actual threshold check.  ds-label should have been the alias, \
not the name from wmi-datacollection-config.xml, same thing for ds-name.  So the \
corrected check looks like:

	<group name="wmivol" rrdRepository = "/opt/opennms/share/rrd/snmp/">
		<threshold type="low" ds-type="wmiLogicalDisk" ds-label="wmiLDName"
		    value="90.0" rearm="95.0" trigger="1" ds-name="wmiLDPctFreeSpace"
                    triggeredUEI="uei.reachlocal.com/sysops/ServerVolSpaceWarning"
                    rearmedUEI="uei.reachlocal.com/sysops/ServerVolSpaceWarning-rearmed">
  </threshold>
	</group>

Still to do: reasonable resource-filter so it's alerting only on C:, D:, etc.  I've \
done them for the linux and netapp vols, shouldn't be too much trouble.

Lars -- I still want to compare configs with you!

Lars,

Which memory ones are you thresholding?  I will then do my own config for those and \
we can compare.  I suspect it's a simple matter of ferreting out which property I am \
misusing.  Then we should both be able to get the kinks worked out of disk \
thresholding.

David,

I am playing with WMI thresholds as well. I do have them working for
Memory, but I have yet to see an alarm for disk space. 

Let me know if you would like to compare xml files.

I'm trying to threshold percentage of free space on Windows logical
vols.  Obviously the value on the threshold below is stupidly high, to
try to get it to trigger.  So far, no dice.  I'm thinking could be I
need to use wmiClass for the ds-type, or perhaps there's another
collector service I should be using, or...wmi-data-collection's
recheckInterval="3600000" is somehow used to determine polling frequency
and hey, who waits an hour to see if something broken? ;)  Someone clued
please look this over and tell me where I forgot to plug in the doll.

thresholds.xml:

	<group name="wmivol" rrdRepository =
"/opt/opennms/share/rrd/snmp/">
		<threshold type="low" ds-type="wmiLogicalDisk"
ds-label="LogDiskName"
		    value="90.0" rearm="95.0" trigger="1"
ds-name="PercentFreeSpace"
 
triggeredUEI="uei.mycompany.com/sysops/ServerVolSpaceWarning"
 
rearmedUEI="uei.mycompany.com/sysops/ServerVolSpaceWarning-rearmed">
		</threshold>
	</group>

wmi-config.xml is correct

wmi-datacollection-config.xml:

            <wpm name="wmiLogicalDisk"
wmiClass="Win32_PerfFormattedData_PerfDisk_LogicalDisk"
                 keyvalue="Name" recheckInterval="3600000" ifType="all"
resourceType="wmiLogicalDisk">
                <!-- Label for this LogicalDisk instance -->
                <attrib name="LogDiskName" alias="wmiLDName"
wmiObject="Name" type="string"/>
...
                <!-- Ratio of the free space available on the logical
disk unit to the total usable space -->
                <attrib name="PercentFreeSpace"
alias="wmiLDPctFreeSpace" wmiObject="PercentFreeSpace" type="Gauge"/>
...
            </wpm>

collectd-configuration.xml:

        <service name="WMI" interval="300000" user-defined="false"
status="on">
            <parameter key="collection" value="default"/>
            <parameter key="thresholding-enabled" value="true"/>
        </service>
...
    <collector service="WMI"
class-name="org.opennms.netmgt.collectd.WmiCollector"/>

threshd-configuration.xml (just tried adding this stuff, although I'm
not sure it's needed):

    <package name="wmi-volume">
        <filter>categoryName LIKE '%Windows%'</filter>
        <include-range begin="1.1.1.1" end="254.254.254.254"/>
        <service name="WMI" interval="300000" user-defined="false"
status="on">
            <parameter key="thresholding-group" value="wmivol"/>
        </service>
    </package>
