What's the Best Way to Monitor Multi-Cloud Environments?

A popular approach is to use Prometheus with Thanos for monitoring. They work well together and can give you a lot of flexibility. Adding Grafana for visualization can make a big difference. You might also want to consider integrating OpenSearch or Loki for logging purposes.

Sentrilite is a great lightweight option that provides a central dashboard for multiple clouds without getting locked into specific tools. It monitors file, process, user, and network activity using eBPF, which can really enhance your visibility into what's happening across your environments.

There's also the combination of Prometheus + Grafana for metrics, and you can use the ELK/EFK stack for logging, although that can be challenging to maintain at scale. Don't underestimate how hard it is to correlate events across different clouds and on-prem setups; it's a real pain!

OpenTelemetry has really simplified things for us. We deploy agents everywhere to gather traces and logs, then send it to a central collector on Kubernetes. It took some setup, but we can monitor file changes, user sessions, and more without being tied to a single vendor. Plus, Grafana makes it easy to see everything at a glance.
