Verified functionality for this task.

Tested for the basic case of an RMI-based collection by starting with a fresh 1.14.0-snapshot built from source. Added the following service to the "example1" package in collectd-configuration.xml:

<service name="Generic-JVM" interval="30000" user-defined="false" status="on"> <parameter key="port" value="10990"/> <parameter key="retry" value="2"/> <parameter key="timeout" value="3000"/> <parameter key="protocol" value="rmi"/> <parameter key="urlPath" value="/jmxrmi"/> <parameter key="rrd-base-name" value="java"/> <parameter key="ds-name" value="generic-jvm"/> <parameter key="friendly-name" value="generic-jvm"/> <parameter key="collection" value="jsr160"/> <parameter key="thresholding-enabled" value="true"/> </service>

And a collector definition:

<collector service="Generic-JVM" class-name="org.opennms.netmgt.collectd.Jsr160Collector"/>

Added a new package to threshd-configuration.xml:

<package name="generic-jvm"> <filter>IPADDR != '0.0.0.0'</filter> <include-range begin="1.1.1.1" end="254.254.254.254"/> <include-range begin="::1" end="ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff" /> <service name="Generic-JVM" interval="30000" user-defined="false" status="on"> <parameter key="thresholding-group" value="generic-jvm"/> </service> </package>

And a corresponding threshold group to thresholds.xml:

<group name="generic-jvm" rrdRepository="/opt/opennms/share/rrd/snmp/"> <threshold type="high" ds-type="node" value="15.0" rearm="10.0" trigger="1" filterOperator="or" ds-name="ThreadCount"/> </group>

Then started a logstash instance (any Java app would work, it's just what I had close to hand) with a JMX-RMI listener on port 10990:

JAVA_OPTS="-Dcom.sun.management.jmxremote.port=10990 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false" bin/logstash -e 'input { stdin { } } output { stdout {} }'

Restarted OpenNMS, requisitioned a node with interface 127.0.0.1 bearing the Generic-JVM service.

Verified expected resource graphs for common JVM MBeans included in the jsr160 collection.

Verified the configured high threshold was exceeded and an event created.
