Subject [jira] [Updated] (AMBARI-19357) Flume metrics can't show if hostname of flume agent is not lowercase
Date Wed, 04 Jan 2017 12:42:58 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-19357?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yao Lei updated AMBARI-19357:
-----------------------------
    Description: 
If hostname of flume agent is uppercase or mixed-case,web client will not show flume metrics
normally.
This is because we will query metric records by lowercase hostname used in ambari ,but the
hostname in METRIC_RECORD is not lowercase (see attached picture),so we will not get any records.This
patch amis to convert hostname of  metric record of flume to lowercase before inserting into
ams hbase.


  was:
If hostname of flume agent is uppercase or mixed-case,web client will not show flume metrics
normally.
This is because we will query metric records by lowcase hostname used in ambari ,but the hostname
in METRIC_RECORD is not lowcase (see attached picture),so we will not get any records.This
patch amis to convert hostname of flume agent metric record to lowcase before inserting into
ams hbase.
