Package org.avaje.metric Description

The main public API for Avaje Metrics.

Avaje metrics provides various metrics for.

• Timers - used to collect timing statistics on methods or sections of code.
• Gauges - used to monitor resource values like memory (used, max etc) and threads (active, max etc).
• Counters - count events like number of logins, number of errors logged.
• Value - used to collect statistics on values that aggregate like total bytes sent etc.

Each of the metrics collect statistics. Generally a MetricReporter is used to periodically collect and report the statistics collected.
