HRegion Metrics
In addition to these base metrics, many aggregate metrics are available. If an entity type has parents defined, you can formulate all possible aggregate metrics using the formula base_metric_across_parents.
In addition, metrics for aggregate totals can be formed by adding the prefix total_ to the front of the metric name.
Use the type-ahead feature in the Cloudera Manager chart browser to find the exact aggregate metric name, in case the plural form does not end in "s".
For example, the following metric names may be valid for HRegion:
- append_rate_across_clusters
- total_append_rate_across_clusters
Some metrics, such as alerts_rate, apply to nearly every metric context. Others only apply to a certain service or role.

| storefiles_size | For an HRegion, the total logical size of the store files that make up that HRegion. For a RegionServer, the total logical size of all the store files of all the HRegions on the RegionServer. This is a logical size because it does not take the replication factor into account. This size does not include space used for metadata such as .tmp, .regioninfo, or .tableinfo. | bytes | cluster, hbase, hnamespace, htable, rack, regionserver | CDH 5, CDH 6 |
| stores | Number of stores | stores | cluster, hbase, hnamespace, htable, rack, regionserver | CDH 5, CDH 6 |
