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 lowcase hostname displayed in 
ambari ,but the hostname in METRIC_RECORD is not lowcase (see attached 
picture),so we will not get any record.
