Many of these will depend on the behaviour of your deployment and use case, so we do not provide specific ranges thresholds to monitor by default. You should monitor and decide what the appropriate limits are for your deployment.
As well as these custom metrics, the prometheus client also collects some generic system metrics and NodeJS specific metrics, see below for more information:
