Add extra metrics to check_kafka script(s)

[jazzl0ver]

Hi,

According to Gwen Shapira's presentation (https://youtu.be/ppDxaqpw8Bw), there're some Kafka metrics that should be monitored in any case (besides the one you've already implemented):

• number of brokers/number of brokers connected to ZK
• under replicated partitions/unavailable partitions
• number of active controllers
• unclean leader elections

Any chances you would add these to the script(s)? It would be really awesome!

These have been on the backburner for a while actually as I'm coding so many different tools on github.

Right now the standard broker write test can test each partition and enforce the ack from a given number of brokers (waiting to ack from a broker that is offline would cause the check to fail with a write self timeout raising a failure condition).

Also the zookeeper checks can check pretty much anything in zookeeper including child znodes and ephemeral znodes used for cluster memberships, znode contents etc.

I think it would be nice to make additional obvious Kafka checks along the lines you have mentioned above and will leave this ticket open until I do.

Do we have any progress made on this request? it will help my requirement as well.

I would have done this at my last gig was a hedge fund that was pretty terrible and didn't let me do any reusable development or anything for github... I'm not working on Kafka at my current gig, but when I next am I will try to get back to this. I don't have an ETA on this and it may be a while...

Thank you Hari.
