Subject [jira] [Commented] (HADOOP-12538) Fix issues of metric path emmitted by GraphiteSink
Date Mon, 02 Nov 2015 06:42:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14984801#comment-14984801

Masatake Iwasaki commented on HADOOP-12538:
-------------------------------------------

{noformat}
... ignoring [.dfs.FSNamesystem.Context=dfs.HAState=active.TotalSyncTimes=20 .Hostname=centos7.MissingBlocks
0 1446359392]
{noformat}

This is the example of problematic metric path logged by graphite collector. Because the value
of {{TotalSyncTimes}} is increasing as the node works, it it should not be part of metric
path. In addition, it is list of counters separated by whitespace and the whitespace should
be replaced.

> GraphiteSink uses tag values as part of metric path using the format like "...tag1=value1.tag2=value..."
but the "=" is not allowed by newer version of Graphite. I addition, there are tag values
containing white spaces.
