Does the template in modules/dse/.. need to be changed as well?

[mrvisser]

Ah yes, thanks. This is tested with manual change to Cassandra log4j-server.properties but I haven't rolled this out using a puppet run to performance yet.

Please don't merge, I may also demote logging of one other component at the same time.

@simong : What do we want to do with this?

[simong]

It's been a while but I can't see any reason this can't be merged. @mrvisser was there anything else you wanted to do here?

[mrvisser]

This PR was made because DataStax wanted me to follow up with enabling the auto-repair OpsCenter service that cronjobbed running read repairs on a regular basis through the cluster. That service generated tons of log messages so we needed to do this before we enabled it on OpsCenter.

[mrvisser]

So when this is enabled, then we can look at enabling the autorepair task that OpsCenter provides.
