Some servers continuously create and delete
tapXY interfaces. Of course OpenNMS is gathering this information from the MIB2 table and starts collecting data for the time, the interface is existent.
At some time you have really many rrd files for

So my question is: What’s the correct approach to ignore network interfaces by
