Agent StatsD Metrics

This guide only applies to Next-Gen WAF customers with access to the Next-Gen WAF control panel. If you have access to the Next-Gen WAF product in the Fastly control panel, you can only deploy the Next-Gen WAF with the Edge WAF deployment method.

StatsD Metrics

Metrics can be reported through StatsD to the service of your choice using the statsd-address agent configuration flag.

Metrics can be filtered using the statsd-metrics agent configuration flag.

The following metrics are reported through StatsD:

  • Counters are counts since last update
  • Gauges are point in time or lifetime metrics
