Stop telegraf from prefixing metric name with plugin name

Telegraf
1

I am using the opcua input plugin. I have its name set to kepware, and all my metric names are prefixed with kepware_. How can I prevent this? I just want the name specified in the node item in the nodes array to be used as the metric name. I tried setting the plugin name to “” but telegraf refused to start with a blank plugin name. I suppose I could use a processor plugin to strip the prefix but that seems like overkill to require run time compute to prevent this configuration issue.

Is there a way to prevent telegraf from prefixing the plugin name onto the metric?

In my case this was actually happening on the TSDB end. I am using Victoria Metrics (which has an influx compatible ingest endpoint), and it was doing the mapping.

  • Field names are mapped to time series names prefixed with {measurement}{separator} value, where {separator} equals to _ by default. It can be changed with -influxMeasurementFieldSeparator command-line flag. See also -influxSkipSingleField command-line flag. If {measurement} is empty or if -influxSkipMeasurement command-line flag is set, then time series names correspond to field names.
