Description
When you delete an xml file in jmx-datacollection.d folder and collectd-configuration points to it, OpenNMS starts and raises a datacollection error. For example:
An undeclared throwable was caught during data collection for interface 1854/10.10.5.110/JMX-Java8-JVM
This message does not help to find the real issue.
Collectd is referencing the datacollection name as you can see here
<service name="JMX-Java8-JVM" interval="300000" user-defined="false" status="on"> <parameter key="port" value="18980"/> <parameter key="retry" value="2"/> <parameter key="timeout" value="3000"/> <parameter key="rrd-base-name" value="java8-jvm"/> <parameter key="collection" value="java8-jvm"/> <parameter key="thresholding-enabled" value="true"/> <parameter key="ds-name" value="java8-jvm"/> <parameter key="friendly-name" value="java8-jvm"/> </service>
So it knows where to search for datacollection files. It should complain about the missing datacollection and/or datacollection file.
