Subject [jira] [Resolved] (AMBARI-18624) Deeper Alerting for Kafka
Date Tue, 13 Dec 2016 09:49:59 GMT


Victor Xu resolved AMBARI-18624.
    Resolution: Duplicate

Let's track this feature in Ambari-19177.

> Deeper Alerting for Kafka
> -------------------------
>                 Key: AMBARI-18624
>                 URL:
>             Project: Ambari
>          Issue Type: Improvement
>          Components: alerts
>    Affects Versions: 2.2.2
>            Reporter: Victor Xu
> Kafka Brokers can become unhealthy while still being 'available', meaning the process
is up and the service is running but it is unusable. Current alerting is only focussed on
if the process is up and running, but it's desired to have alerting that is focussed on testing
for these situations in which the component is up, but non functional. 
> Example:
> Sometimes the brokers are not working but ambari still registers them as green. I have
seen this in at least one case, OutOfMemory in the broker logs. This could easily be reproduced
by dropping the broker heap and creating many topics to blow the heap. Ambari will still register
kafka as healthy.
> We need the Kafka team to identify a script that Ambari can run to probe the Kafka process
to achieve this deeper health alerting capability.
