Can't to exclude attributes

[laa88rf]

Hello.

I have unneded Kafka metrics. For example:

# HELP kafka_network_RequestMetrics_50thPercentile Attribute exposed for management kafka.network:name=ResponseQueueTimeMs,type=RequestMetrics,attribute=50thPercentile
# TYPE kafka_network_RequestMetrics_50thPercentile untyped
kafka_network_RequestMetrics_50thPercentile{name="LocalTimeMs",request="AddOffsetsToTxn"} 0.0
kafka_network_RequestMetrics_50thPercentile{name="LocalTimeMs",request="AddPartitionsToTxn"} 0.0

I want delete it from /metrics page.
I tried the following:

blacklistObjectNames: ["kafka.log:*", "kafka.network:name=ResponseQueueTimeMs,type=RequestMetrics,attribute=50thPercentile", "kafka.cluster:type=Partition,*"]
rules:
  - pattern: ".*"

also:

excludeObjectNameAttributes:
        "kafka.network:type=RequestMetrics":
                - 50thPercentile

Also:

rules:
- pattern: "(.*)"
  name: "$1"
  action: drop
  labels:
    __name__: ".*(_50thPercentile)$"

and many more options. And none of them work.
Version 1.1.0

Please help me.
Also, please add relevant information about exclude/drop metrics.

Thank you.

Ok. I have a progress.

When I using:

autoExcludeObjectNameAttributes: true
includeObjectNameAttributes:
  "kafka.network:type=RequestMetrics":
    - "50thPercentile"

rules:
  - pattern: ".*"

I have only 50thPercentile metric. It's not very obvious.
Of course, I can list the metrics, but it's not convenient

@laa88rf I understand the inconvenience. This was a design decision to prevent performance issues when using regular expressions.

The current algorithm can use a map to include/exclude object name attributes, which is fast. Using regular expressions would result in an algorithm that is O(MN), dramatically affecting scrape time.

@dhoard thank you for your answer. Could you please provide any examples.
I tried to write a configuration file using AI, but I got strange variables like drop and skip, which I didn't find in the examples.

The integration tests are the best examples of the various configuration options. The subdirectories contain example exporter.yaml files.
