Hello I am checking out Chukwa. I have a few questions I was hoping the mail list could answer :-)
1)Does Chukwa agents communicate to collectors over http? Or some other protocol? The agent configuration makes me believe that: http://incubator.apache.org/chukwa/docs/r0.4.0/admin.html#Configuration 2) And the docs it seems an Agent will pick a collector at random and then use that collect until there is a problem in communicating with it. How do you think the agent/collector would act if they have a load balancer between them? For example, the agent configuration would have just one url http://collector-loadbalancer. example.com:8080/ The load balancer would have 1 or more collectors behind it saving the chunks it receives to disk or hadoop. 3) Does chukwa have any “end-to-end” reliability features for message delivery? For example, a collector may receive the chunk from the agent but it may have a problem writing it to the data store. (ie. Disk space full, connection to hadoop down) . Will the agent be notified that the chunk was not processed for a certain reason and the agent is told to cache to disk the missed message? Thanks for the info! -tp-
