Most Important RegionServer Metrics
- Previously, this section contained a list of the most important RegionServer metrics.
- However, the list was extremely out of date. In some cases, the name of a given metric has
- changed. In other cases, the metric seems to no longer be exposed. An effort is underway to
- create automatic documentation for each metric based upon information pulled from its
- implementation.
+ Note: Counts are usually over the last metrics reporting interval.
+
+
+ hbase.regionserver.regionCount
+ The number of regions hosted by the regionserver
+
+
+ hbase.regionserver.storeFileCount
+ The number of store files on disk currently managed by the
+ regionserver
+
+
+ hbase.regionserver.storeFileSize
+ Aggregate size of the store files on disk
+
+
+ hbase.regionserver.hlogFileCount
+ The number of write ahead logs not yet archived
+
+
+ hbase.regionserver.totalRequestCount
+ The total number of requests received
+
+
+ hbase.regionserver.readRequestCount
+ The number of read requests received
+
+
+ hbase.regionserver.writeRequestCount
