----------------------------------------
Lars,
It seems you are at the spot where I was a while back
http://issues.apache.org/jira/browse/HADOOP-4594. (pretty much the spot that
inspired hadoop-cacti-jtg)
In a nutshell, hadoop+hbase has built in ganglia support. It works in that in
does push metrics to a ganglia cluster, but it has its detractions. For me
these are, often changing attributes and object names, missing vivid
documentation of what counters mean, and being forced into a monitoring system
(ganglia).
On one hand it makes a lot of sense to call cacti/nagios scripts "contrib" and
take the stance that they are not easily unit testable and thus do not belong
in hadoop core. Of course, you can reverse the argument "just because you can
patch in ganglia support, does that mean that only an NMS that can be patched
in (pushed based nms) should be officially supported"
Thus we have hadoop-cacti-jtg, because ganglia does not meet everyone's needs
but it is the only NMS that seems to be able to make its way in. Every other
NMS seems to be classified as unneeded contrib.
