Metrics in 0.96Lars George 2012-06-15, 08:07
Hi,
I propose that we clean up the metrics for 0.96 as well (if that is not already underway. This includes switching to Hadoop Metrics v2 and adding all missing stats, as well as fixing those that are misleading or useless. For that reason I talked to our friends at Sematext during the Buzzwords HBase workshop, as well as to our internal HBase team. We all seem to agree and I'd be happy to setup some sort of call/task force to discuss what we need to work on etc. Obviously I would love for someone from the FB team to also partake as they have done heaps lately on that end - but I also understand if that is a timing issue. What do y'all think? My reasoning is that 0.96 might become 1.0, but I would love for the metrics to be stable by then. Cheers, Lars

Re: Metrics in 0.96Andrew Purtell 2012-06-15, 15:41
+1
And at the same time IMHO it's worth asking if we have everything covered with a meaningful metric, and add if missing, as well as remove those not useful. Metrics2 is in Hadoop core 1 and 2. There was a backport into 1 at some point but the latest (1.0.3) has it for sure. - Andy On Jun 15, 2012, at 8:07 AM, Stack <[EMAIL PROTECTED]> wrote: > On Fri, Jun 15, 2012 at 1:07 AM, Lars George <[EMAIL PROTECTED]> wrote: >> Hi, >> >> I propose that we clean up the metrics for 0.96 as well (if that is not already underway.

Re: Metrics in 0.96Lars George 2012-06-15, 15:54
Hi Andy,
Yes, that is exactly the plan. I am sure we have areas where we simply lack metrics, I have noted this down somewhere and will dig up the details. It would also consolidate (and close out) all open "Improve HBase Metrics" JIRAs.

Re: Metrics in 0.96Elliott Clark 2012-06-15, 17:04
Sounds great.
I also think we should start moving away from just averages, and move towards using the histograms. Right now the histograms are broken, they don't get exported into jmx but I've got a fix I think (HBASE-6211). I would also like to look into tying Server/Region Load in with metrics. Right now they are very similar to RegionServerMetrics/RegionServerStatistics and seems like there is a lot of overlap.

Re: Metrics in 0.96Enis Söztutar 2012-06-15, 23:47
Big +1.
We also need to rename some of the metrics to be consistent in naming, and make some it more configurable (like enable/disable per-region / per-schema metrics, etc) See: https://issues.apache.org/jira/browse/HBASE-5601.

Re: Metrics in 0.96Lars George 2012-06-16, 08:27
Hi Enis,
Hecks yeah, there are so many different prefixes alone that make finding what you need nearly impossible without practice. I agree on the configurable metrics backend, that will allow to enable what is needed optionally. We just have to find a good approach. One of the things that FB has learned the "hard" way is that some metrics at scale are not sustainable. We could, even think about building in some reasonable heuristics to disable some high throughput metrics when a threshold is crossed.

Do we have an umbrella JIRA for this? Seems like there is a lot of work to
be done on this and it would help to have one similar to HBASE-5305 for the version compatibility stuff. We can link HBASE-5601 off it to start. If not, I can create one.

Independent of this something I would like to be able to do is log metrics to a file as well as Ganglia concurrently, and metrics2 can do that.

I'm excited about the new accurate histogram, however I don't think that
we'll get it when we move to metrics2. Any direct usage would break backward compat for all older hadoop installs. For backwards compatibility on hadoop versions we will either have to create a shim layer with reflection, or pull the code in. Since we already have a MeticsHistogram I think pulling the code into hbase may be the right choice.

I suggest continuing discussion on HBASE-4050.

Metrics2 is in both Hadoop 1 and 2. (?)
But my thing was the latter point below anyhow.

Re: Metrics in 0.96Andrew Wang 2012-06-30, 00:41
I think Elliot's concern with the histogram improvements is that if it goes
in hadoop-common, HBase is only going to get it after it gets rolled into a new hadoop-common release and HBase bumps the version on the hadoop-common dependency. I don't think this is so bad. For now though, I'm willing to maintain an HBase patchset against this future improved hadoop-common until it's actually released.
