Kudu Replica Metrics

Reference information for Kudu Replica 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 Kudu Replica:

  • kudu_all_transactions_inflight_across_clusters
  • total_kudu_all_transactions_inflight_across_clusters

Some metrics, such as alerts_rate, apply to nearly every metric context. Others only apply to a certain service or role.

Description
Number of bytes read by scan requests. This is measured as a raw count prior to application of predicates, deleted data,or MVCC-based filtering. Thus, this is a better measure of actual IO that has been caused by scan operations compared to the Scanner Bytes Returned metric. Note that this only counts data that has been flushed to disk, and does not include data read from in-memory stores. However, itincludes both cache misses and cache hits.
