Priyo Mustafi updated HADOOP-7324:
----------------------------------
Attachment: HADOOP-7324.patch
Latest patch addressing some feedback.
Few other things that were not mentioned here but I got in an email from Luke
1) If for a metric no slope is configured, default the slope to "positive" for
Counters. After doing this, I am seeing positive slope graphs for those
metrics. Not sure if this was expected behavior
2) The code assumes the call to putmetrics is done in a threadsafe manner.
> Ganglia plugins for metrics v2
