Question about Flink metrics

[neha goyal <ne...@gmail.com>]

Hello,
I have a question about the Prometheus metrics. I am able to fetch the
metrics from the following expression.
sum(flink_jobmanager_job_numRestarts{job_name="$job_name"}) by (job_name)
Now I am interested in only a few jobs and I want to give them a label. How
to achieve this? How to give an additional label to Flink Prometheus
metrics so that I can fetch the metrics only for those jobs having that
label? This tag I need to set on the job level. Few jobs will have that tag
and others won't.

Hi Neha,

For the jobs you care about, you can attach additional labels using
`scope-variables-additional` [1]. The example located in the same page
showcases how you can configure KV pairs in its map configuration. Be sure
to replace the reporter name with the name of your prometheus reporter!

Best,
