VerneMQ can be monitored in several ways. We implemented native support for Graphite, MQTT $SYS tree, and Prometheus.
The metrics are also available via the command line tool:
Or with:
Which will output the metrics together with a short description describing what the metric is about. An example looks like:
Notice that the metrics:
Are no longer used (always 0) and will be removed in the future. They were replaced with mqtt_connack_sent
using the return_code

label is used instead.
The output on the command line are aggregated by default, but details for a label can be shown as well, for example all metrics with the not_authorized
label:
All available labels can be show using vmq-admin metrics show --help
.
