Develop Monitoring Concept

[Miradorn]

There are different ways of how we could implement Monitoring.
Current Ideas:

1. Use Cloudwatch

The cloudwatch cluster agent can be used to push metrics to cloudwatch

Cons:

• No histograms, see here and here

2. Use Managed Prometheus

Install Prometheus to the cluster to forward metrics to AWS managed prometheus

Pros:

• Long term storage available

Cons:

• Does not help with scaling pods

3. Use Prometheus Operator

Pros:

• Dashboards can be defined for CRDs via default dashboards
• State of the art in k8s

Cons:

• No long term storage

4. Use Prometheus Operator with Managed Prometheus

Use a combination of both, 3 and 4.

Pros:

• all pros of 3 & 4

We have to come up with an ADR outlining our decisions.

Das HelmChart gibt es schon (nicht 100% aktuell), aber StatsD Support ist (noch) nicht exposed:

The cloudwatch cluster agent project seems to be quite stale.
