{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.
