If you assign the Service "OpenNMS-JVM” and "JDBC-PostgreSQL” you will get internal information from OpenNMS itself with JMX and some infos from the PostgreSQL database tables with the JDBC collector. There are also pre-configured JMX data collections for * Cassandra when you use it with NewTS * NewTS itself * Kafka when you use it as a Message Broker with Minion * Minion itself You find the configuration and metrics in jmx-datacollection-config.d.

I never thought of doing it that way, but is exactly what I wanted.

Not sure how you would get around that as the search results are driven by the search engine used. > > Regards, > John > > > -----Original Message----- > From: Ronny Trommer [mailto:[email protected]] > Sent: Tuesday, 17 October 2017 3:44 PM > To: General OpenNMS Discussion <[email protected]> > Subject: Re: [opennms-discuss] Monitoring a service on OpenNMS server only listening on loopback interface > > > > Ok I’ll try it again and marked the mail as plain text :) > > Do you have OpenNMS and the PostgreSQL database running on the same server? > > Add 127.0.0.1 as an interface of your OpenNMS server and assign the PostgreSQL service on the 127.0.0.1 interface and use the OPENNMS_JDBC_HOSTNAME parameter instead of localhost.
