Subject [jira] [Created] (HDFS-7465) Html view for nntop: top users of name node
Date Tue, 02 Dec 2014 17:12:12 GMT
Maysam Yabandeh created HDFS-7465:

             Summary: Html view for nntop: top users of name node
                 Key: HDFS-7465
                 URL: https://issues.apache.org/jira/browse/HDFS-7465
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Maysam Yabandeh
            Priority: Minor
             Fix For: 2.7.0

nntop (HDFS-6982) maintains the list of top users of the name node and export the list via
jmx. An external monitoring tool can then draw graphs of the top users using jmx interface.
For small-scale deployments that are not yet equipped with an external monitoring tool, however,
it would be useful to show the list of recent top users using a html view. The html page lists
the top users of each name node command in the past 1, 5, 25 minutes (configurable). The details
can be found in the design doc of nntop: https://issues.apache.org/jira/secure/attachment/12665990/nntop-design-v1.pdf
