vmagent relable metrics about victoriametrics HOT 12 CLOSED

Hi!

May I ask if you've tried:

  # current config (I'm not sure if there is a formatting issue of GitHub markdown?)
  - if: '{name!~"kafka_consumergroup_lag_sum"}'
  # have you tried this one?
  - if: '{__name__!~"kafka_consumergroup_lag_sum"}'

Please paste your config within a code block so that it could be formatted correctly and potentially easier to solve.

Also I saw some test case in this repo which might be helpful:

- action: drop
  if: '{__name__!~"smth"}' 

And you could debug the relabel config by the debug button. See: https://docs.victoriametrics.com/vmagent/#relabel-debug (Metric-level debugging)

from victoriametrics.

I tried the configuration myself and the relabel result should be like:

You can debug on other metrics to see if they are dropped (but somehow preserved in real-world usage). and see if vm maintainers have other suggestion for ya ^_^

@jiekun, other metrics is filtering like on second image

from victoriametrics.

@jiekun , shure. "name" was sintax error. Im using:
- if: '{__name__!~"kafka_consumergroup_lag_sum"}'

This one doesnt help:

- action: drop
  if: '{__name__!~"kafka_consumergroup_lag_sum"}' 

from victoriametrics.

Okie, could you check the debugging page for this metric to see how the relabel config work and paste some screenshots here

from victoriametrics.

@jiekun , thats it?

from victoriametrics.

cmiiw, you intend to drop metrics whose __name__ is not equal to kafka_consumergroup_lag_sum. But the kafka_consumergroup_lag_sum is dropped and other metrics are preserved?

from victoriametrics.

@jiekun, no. Metrics up to kafka_consumergroup_lag_sum realy drop as expected, but metrics after it are also preserved (it is not expected). Expect to preserved only one metric with name kafka_consumergroup_lag_sum.

Looks strange.

Could you try a simple example for it:

    metric_relabel_configs:
    - source_labels: [__name__]
      action: keep
      regex: '^kafka_consumergroup_lag_sum$'

from victoriametrics.

@f41gh7, it works! Thanks a lot!

from victoriametrics.

It looks like everything works as intended when using the following if condition with action: drop in relabeling rules:

- if: '{__name__!~"kafka_consumergroup_lag_sum"}'
  action: drop

1. It drops all the metrics with names other than kafka_consumergroup_lag_sum. See this example
2. It keeps kafka_consumergroup_lag_sum metrics. See this example.

@zentkhv , probably, you hit some bug in old version of vmagent. I suggest upgrading vmagent to the latest available release in order to rule out this possibility. The latest release contains all the bugfixes from all the previous releases.

from victoriametrics.

@valyala, Thanks for the option. There was also the idea that this is connected with the old version, but so far there is no possibility to update.

p.s. Yes, the problem was not reproduced in metric-relabel-debug.
