Subject [jira] [Updated] (AMBARI-3853) Poll Ganglia metrics from rrd.py with POST instead of GET
Date Fri, 22 Nov 2013 11:51:35 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-3853?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
