prometheus - Victoria Metrics - Delete time series with missing label

Question

I using a Victoria Metrics cluster. I have two timeseries that differ because one is missing a label. My question is how to delete the one with the missing label ? I see that I can use a time series selectors list for the match[] value, but how to select a time series with a missing label ?

Thanks.

Answer 1

Try to query for the missing label using !="some_label_value_that_doesnt_exist" like in the following example:

some_metric{missing_label!="xxxxx"}

All time-series without the missing_label should be found.
