Metrics & dashboard

[NickPriv]

Metrics and dashboard set up to visualize:

• customer traffic (how many calls to an API per fixed duration e.g. 5 min)
• errors
• latency

Here's an idea: https://grafana.com/blog/2022/04/26/set-up-and-observe-a-spring-boot-application-with-grafana-cloud-prometheus-and-opentelemetry/

It's also possible to build our own monitoring solution:

• post all events to a Mongo collection
• dashboard can query from events collection for display via a UI

It's probably overengineering, but an alternative to keep in mind.

Update: configured Librato. Will evaluate if there are more metrics we want to see which are missing (e.g. customer traffic, errors, or latency metrics)

[NickPriv]

Another update, Librato only shows the last hour of data for a free plan. Good for a feature release but not for long-term data analysis. Will evaluate other options.

Enabled Sentry as another add-on to the pure-monk app. Will look into the features we can leverage from it.
