JMX Exporter - How to handle mBeans with string values

[prz...@zelazko.org]

Hi,

I'm trying to configure JMX exporter for kafka-connect and I ran into a problem. Some of the metrics I am interested in, e.g. connector and task status, are exported as string values. Unfortunately such beans seem to be ignored:

FINE: scrape: 'kafka.connect{type=connector-task-metrics, connector=_GL_GAWRON_BUSINESSPROCESSSTARTERADAPTER_TEST-STATUS_, task=0}status': paused

FINE: Ignoring unsupported bean: kafka.connect<type=connector-task-metrics, connector=_GL_GAWRON_BUSINESSPROCESSSTARTERADAPTER_TEST-STATUS_, task=0><>status: paused

Is there a way to handle such values (map to int?)?

Regards,

Przemek

I actually tried something very similar, but no dice:

- pattern: 'kafka.connect<type=connector-task-metrics, connector=(.+), task=(.+)><>status: (.+)'

name: kafka_connect_task_status

value: 1

labels:

connector: "$1"

task: "$2"

status: "$3" 

It seems like tabular values (that seems to be what is processed in the post you linked to) are handled differently than plain atomic strings. I am still getting the "Ignoring unsupported bean" message.

I'd expect that to work. Do you have attrNameSnakeCase set?

 No, I don't have attrNameSnakeCase set. I didn't think it would make any difference, but I can try tomorrow when I'm back at the office.
