Prometheus
EMQX Broker provides emqx_statsd plug-in, which is used to output the monitoring data of the system to the third-party monitoring system.
Take Prometheus as an example:
emqx_statsd supports pushing data to Pushgateway, which is then pulled by Promethues Server for storage.
Tip
emqx_statsd does not support the pull operation of Prometheus.
Configuration
The emqx_statsd plugin internally starts a timer to collect the monitoring data in EMQX Broker every interval.
For the specific fields and meanings of the monitoring data pushed by emqx_statsd, see Metrics & Stats
