@sreelu27 you should be able to use the configuration excludeObjectNames to exclude the MBean that is providing the metrics.

from jmx_exporter.

@sreelu27 Currently I'm are working on migration to the new Prometheus Java client_library.

I feel filtering JVM metrics is low priority since most uses/use cases I have seen want to monitor these metrics.

from jmx_exporter.

Hi @dhoard
Can we get any help on the filtering issue, please?

from jmx_exporter.

@sreelu27 are you wanting any of the metrics from the RequestMetrics MBean?

from jmx_exporter.

Hi @dhoard ,

Do you want any of the metrics from the RequestMetrics MBean ? – No

The issue here is when I apply this filter, all network related metrics are coming but along with that JMX and JVM metrics also coming that's the problem.

Hi @dhoard,

I tried to add blacklistObjectNames as below, but still I am getting the jvm metrics,
jvm_threads_state{state="NEW",} 0.0
jvm_threads_state{state="TERMINATED",} 0.0
jvm_threads_state{state="RUNNABLE",} 21.0

    blacklistObjectNames: ["jvm.threads*"]
    rules:
    - pattern : kafka.network<type=RequestMetrics, name=LocalTimeMs, request=Fetch><>Count

from jmx_exporter.

@sreelu27 if you don't want any request metrics, then you should use...

excludeObjectNames: ["kafka.network:type=RequestMetrics,*"]

... which will filter all all MBean's with ObjectNames that match.

from jmx_exporter.

Hi @dhoard ,

No I want to exclude the jvm metrics

Is there any way I can do that?

We are using jmx version 0.18.0

from jmx_exporter.

@sreelu27 some questions... since this is different than what you originally requested...

I am trying to create a pattern for the below Kafka metrics to be filtered:
kafka_network_RequestMetrics_Count

Are you wanting to exclude all JVM metrics?
Are you running the exporter as a Java agent?

from jmx_exporter.

Hi @dhoard ,
apologies for the confusion.
Are you wanting to exclude all JVM metrics? yes
Are you running the exporter as a Java agent? yes

excludeObjectNames: ["java.lang:*"]
rules:
  - pattern: ".*"

All of the above didn't work.

Is the MBean, that I am using is incorrect ? or is it that we cant exclude these default metrics (jvm & jmx) ?

Could you please help me here @dhoard ? Thanks :)

@sreelu27 please upgrade to the latest version.

Hi @dhoard ,

I am using 0.20.0 version. Uplifted from 0.18.0 to 0.20.0 for configuration excludeObjectNames

Thanks,

@sreelu27 excludeObjectNames is a global setting for an MBean. If you exclude the MBean there is no need to exclude specific attributes.

excludeObjectNames: ["java.lang:*"]

Should exclude the MBean.

@sreelu27 apologies, I've been extremely busy with work.

After doing some testing and research, it appears what you are trying to filter is not supported. I should have caught it earlier.

#696

from jmx_exporter.

Hi @dhoard,

Thank you for the confirmation.Will this be supported in the future version, the enhancement that you have linked in the previous comment : #696

Thanks,
Sree

from jmx_exporter.

Working as designed. Filtering of JVM metrics is an enhancement tracked via #696
