Subject What information does FetchRequestAndResponseMetrics name contain?
Date Mon, 02 Jun 2014 12:16:31 GMT
Hello everyone,

We are adding Kafka 0.8.x monitoring support to SPM
<http://sematext.com/spm/> here at Sematex and I have one question about
JMX Kafka beans:

In Jconsole for my local setup I see:

kafka.consumer:type="FetchRequestAndResponseMetrics",name="
af-servers-ConsumerFetcherThread-af-servers-wawanawna-Dell-1401353748289-fcaaea29-0-0-host_localhost-my-port_9092-FetchRequestRateAndTimeMs
"


This long name actually contains consumer group id ('af-servers'), host
('wawanawna-Dell'), and a few other things, which I can recognize as a
human….

Maybe someone can clarify for me what this line contains, especially part
'1401353748289-fcaaea29-0-0'. What timestamp represents here? What 'fcaaea'
means? Does it just id of something? What is '-0-0-' here? Does it relates
to partitions somehow?

Thx and best regards from Sematext.
