@Nagesh Bansal https://signoz.io/docs/userguide/drop-metrics/ - I need to drop metrics for few targets. I found this documentation to do so. It’s quite unclear, where to place this config. I installed signoz using helm chart.

Hey @Hari Krishna, you need to use the mentioned params in the otel-collector config.

Helm charts

either you can set the filter at signoz-collector at: https://github.com/SigNoz/charts/blob/5538e02aa9e9423470653a81df13485cac157f9b/charts/signoz/values.yaml#L1321 or as you're running k8s-infra which comes up with otel-collectors also so you can place the filters at: https://github.com/SigNoz/charts/blob/5538e02aa9e9423470653a81df13485cac157f9b/charts/k8s-infra/values.yaml#L659

global:
  storageClass: standard

clickhouse:
  installCustomStorageClass: true

otelCollector:
  config:
    processors:
      filter/drop_metrics_by_label_values:
        metrics:
          datapoint:
            - attributes["http.target"] == "/"
            - attributes["http.target"] == "/healthz"

I made this change and it doens’t look like it works. This change is present in

signoz-otel-collector

configmap, though.

could you please check the metrics not the traces

You mean here?

/

-> is still here

try with url.path instead http.target

Still the same 😞

just to be sure does the metrics you want to drop have an attribute named

http.target

or

url.path

or `http.route`with a value of

/

or

/healthz

? you can use the loggingexporter with

verbosity: detailed

to check what your data looks like

otelCollector:
  config:
    processors:
      filter/drop_spans_by_attribute_values:
        traces:
          span:
            - 'attributes["http.target"] == "/"'
            - 'attributes["http.target"] == "/healthz"'

    service:
      pipelines:
        traces:
          processors:  [filter/drop_spans_by_attribute_values, signozspanmetrics/delta, batch]

This worked.

This would be for traces right?

Yeah, i was not exporting any metrics from my app, just the traces.

so it uses the metrics and traces both, you can take a look at this: https://signoz.io/docs/userguide/metrics/#view-details-about-an-application
