Metric Expressions

A metric expression generates the time series. It is a comma-delimited list of one or more metric expression statements.

A metric expression statement is the name of a metric, a metric expression function, or a scalar value, joined by one or more metric expression operators.

See the FAQ which answers questions concerning how to discover metrics and use cases for scalar values. For a list of all the supported metrics, see the Cloudera Manager Metrics reference documentation.

Metric expressions support the binary operators: +, -, *, /.

Here are some examples of metric expressions:
  • jvm_heap_used_mb, cpu_user, 5
  • 1000 * jvm_gc_time_ms / jvm_gc_count
  • total_cpu_user + total_cpu_system
  • max(total_cpu_user)
