Re: The complete list of metrics

Jeff, Check out the section on discovering metrics: http://hbase.apache.org/book.html#discovering.available.metrics In particular, it gives you the URL to use with teh JMX endpoint Yu mentioned to get the metrics with descriptions that explain what they are. On Fri, Mar 3, 2017 at 12:13 PM,

Re: Need guidance on getting detailed elapsed times in every stage of processing a request

Yu Of the patches attached to HBASE-15160, do I need to apply all (v2, v3, ...) or just HBASE-15160.patch ? Also how would I know against what version this patch was created? thanks From: jeff saremi Sent: Friday, March 3, 2017

Re: Need guidance on getting detailed elapsed times in every stage of processing a request

Thanks a lot Yu These are truly the metrics we care about about at this point. It is sad to see that such important metrics were removed from the code. I will try to apply your patch on my own to the version of HBase we have. We definitely need these. Other solutions like HTrace are not as

Re: The complete list of metrics

It seems we're truly missing such docs... Other than reading source code, an easier way is to check the http://:/jmx page of a running regionserver, you could see all metrics there. Best Regards, Yu On 4 March 2017 at 01:54, jeff saremi wrote: > Is there a page listing

The complete list of metrics

Is there a page listing all metrics in HBase? I have checked this: http://hbase.apache.org/book.html#hbase_metrics but it's only the most important ones not the whole thing

Re: Need guidance on getting detailed elapsed times in every stage of processing a request

Hi Jeff, If the question is simply monitoring HDFS read/write latencies, please refer to HBASE-15160 , there's a patch but not committed yet, and probably cannot apply cleanly on current code base, but still some good reference IMHO, so JFYI. To

Re: Why doesn't HBase use github pull requests

The ASF requires all the dicsussions to be recorded on the services deployed by ASF, or the mailing list. So even if you want to use github PR to submit patch, we still need to discuss on jira... 2017-03-03 22:05 GMT+08:00 Ted Yu : > For github pull requests to go through

Re: Why doesn't HBase use github pull requests

For github pull requests to go through Jenkins QA, there is certain infrastructure setup needed. Due to lack of such setup, we still go with attaching patches. FYI > On Mar 3, 2017, at 5:11 AM, Kahlil Oppenheimer > wrote: > > Hi all, > > I just had my first

Why doesn't HBase use github pull requests

Hi all, I just had my first patch merged into master, and throughout the process I was wondering why HBase doesn't use github and pull requests to manage contributions. I noticed that there is a mirror of the repo available at https://github.com/apache/hbase, but it seems like everything is done
