Changed rrd step 300 to 30. After that remove all rrd/jrb files for new collection. and restart opennms to make changes. I checked again but didn't change time interval as well as stop getting data in graph.
I recently installed opennms 27.1.1. Time interval in opennms graph is 5 minutes. I want to reduce to 30 second. I googled and found some related result. And made changes in datacollection-config.xml like below
Any suggestions what am I doing wrong. It will be very helpful. Thanks in advance
