[jira] [Created] (HBASE-3710) Book.xml - fill out descriptions of
metrics
Book.xml - fill out descriptions of metrics
-------------------------------------------
Key: HBASE-3710
URL: https://issues.apache.org/jira/browse/HBASE-3710
Project: HBase
Issue Type: Improvement
Reporter: Doug Meil
Priority: Minor
I filled out the skeleton of the metrics in book.xml, but I'd like one of the committers to fill in the rest of the details on what these mean. Thanks! :-)
For example..
-------
I'm assuming that these are referring to the LRU block cache in memory. I'd like to docs to state this (for the sake of clarity) and also the units (e.g., MB).
hbase.regionserver.blockCacheCount
hbase.regionserver.blockCacheFree
hbase.regionserver.blockCacheHitRatio
hbase.regionserver.blockCacheSize
-------
This is read latency from HDFS, I assume...
hbase.regionserver.fsReadLatency_avg_time
hbase.regionserver.fsReadLatency_num_ops
hbase.regionserver.fsSyncLatency_avg_time
hbase.regionserver.fsSyncLatency_num_ops
hbase.regionserver.fsWriteLatency_avg_time
hbase.regionserver.fsWriteLatency_num_ops
----------------
point in time utilized (i.e., as opposed to max or trailing) memstore I assume, would be nice to document.
hbase.regionserver.memstoreSizeMB
---------------
obvious, but might as well document it
hbase.regionserver.regions
--------------
This is any Put, Get, Delete, or Scan operation, I assume?
hbase.regionserver.requests
--------------
detail on these would be nice, especially for tips on if there are any critical numbers/ratios to watch for.
hbase.regionserver.storeFileIndexSizeMB
hbase.regionserver.stores

I decided to take a crack at this. I looked at HRegion and RegionServerMetrics for most of this.
