The settings in the default monitoring/values.yml are currently somewhat out of date.
Many values are being overridden in production.
Ideally we would like to:
- have less prod overrides (ie. bring as many of the prod settings as possible into the defaults)
- have a setup that verifiably works in the dev setup - in particular the values coming from the blackbox exporter (that monitor the main backend) should work locally.
Here are the current production overrides - note that some values are injected via terraform templates (eg ${graphql_playground_url}) - don't know how best to set defaults for that. At least for dev setup we should probably hard code the values.
