Oleksandr Diachenko updated AMBARI-3853:
----------------------------------------
Description: Actually we are getting metrics from rrd.py with GET, and it
limits number of parameters could be passed. When desired metrics quantity
exceeds limit of 50 we are requesting all metrics and it is bad for
performance. The idea is make POST requests and pass all metrics to improve
performance.
> Poll Ganglia metrics from rrd.py with POST instead of GET
