Emakin publishes the internal application performance metrics in JSON or text based format.
By default only web request metrics are collected and workflow metrics are disabled by configuration and can be enabled with set AppMetrics/Enabled flag to "true" value.
Emakin also supports the open metrics (Prometheus) based format and can be enabled by setting AppMetrics/Prometheus/Enabled flag to "true" value. When it is enabled default standard metrics endpoint uses the prometheus format.
Text Format
Text based application metrics data can be accessed from "http://<servername>:7180/metrics-text" url.
