Subject HBase performance metrics gotchas?
Date Wed, 19 Jan 2011 17:30:05 GMT
Hi,

Are there any gotchas around turning on HBase performance metrics 
gathering/publishing (the stuff described on 
http://hbase.apache.org/docs/current/metrics.html), such as "if you turn this 
on, be prepared to pay N% loss in performance" or some such?

Also, the "file" plugin just logs performance metrics to a log file, is that so?

Thanks,
Otis
P.S.
http://hbase.apache.org/docs/current/metrics.htm may be a bit out of date -
I see additional metrics mentioned on 
https://issues.apache.org/jira/browse/HBASE-2838
