Monitoring your App
When you run MooseJS app localy you can visit localhost:4000/metrics
to see the metrics that your moose app is collecting. This endpoint is also available on your production docker container
These metrics are collected using Prometheus (opens in a new tab) instrumentation and metrics format.
Prometheus Metrics
The metrics endpoint will show you latency data for every single http endpoint that a http request has been made to. If no data is shown for a http endpoint then no http requests have been made to this http endpoint.
Here is an example of some metrics that are sent to this http endpoint
# HELP latency Latency of HTTP requests.
