Subject [jira] Commented: (CHUKWA-366) Custom Tags
Date Tue, 04 Aug 2009 19:42:14 GMT


Ari Rabkin commented on CHUKWA-366:

Jerome, can I take your response for consent?  The only change to ChunkImpl and the existing
tagging mechanism and tag-handlign code is adding the Chunk.getTag(String) method.  Which
shouldn't do any harm, even if we later do something nonstandard with tags; at worst, it'll
give misleading results.  

I thought about pushing the functionality into a helper class, and decided against it, since
if tags are a standard mechanism (and they should be), then a default tag format seems like
a reasonable thing to standardize and push into Chunk.

> Being able to specify custom tags for a machine.
> I would like to be able to tag a machine as part of a specific stack, such as Stack1
and Stack2, which is already implemented as the 'cluster' tag specified in chukwa-agent-conf.xml.
I would also like to be able to tag each machine according to its role, such as WebServer
or DataBase. This is not currently doable. The best solution would probably be to allow arbitrary
tags. This functionality should be exposed also in the use of, such that I can filter
on any tag.
