Interface MetricsProducer

public interface MetricsProducer
Prior to 2.1.0 Accumulo used the Hadoop Metrics2 framework. In 2.1.0 Accumulo migrated away from the Metrics2 framework to Micrometer. Micrometer suggests using a particular naming convention for the metrics. The table below contains a mapping of the old to new metric names.
Summary of Metric Changes
Old Name Hadoop Metrics2 Type New Name Micrometer Type Notes
N/A N/A "accumulo.server.idle" Gauge Indicates if the server is idle or not. The value will be 1 when idle and 0 when not idle.
N/A N/A "accumulo.compactor.majc.stuck" LongTaskTimer
N/A N/A "accumulo.compactor.entries.read" FunctionCounter Number of entries read by all threads performing compactions
N/A N/A "accumulo.compactor.entries.written" FunctionCounter Number of entries written by all threads performing compactions
currentFateOps Gauge "accumulo.fate.ops" Gauge Was previously named "accumulo.fate.ops.in.progress". Changed to better reflect what the gauge is actually tracking which is all the current fate ops in any state.
