Hey everyone,
Just wrapped up a six-month rollout of Sysdig across our main production GKE clusters (~200 nodes, mixed workloads) and wanted to share some real hands-on experience. We were primarily looking for a unified platform for container security, monitoring, and forensics to replace a patchwork of tools.
The deployment itself was pretty smooth. The Helm chart for the agent is well-maintained. We installed it via our GitOps pipeline without major hiccups. The agent's resource footprint was a big concern for us upfront. After tuning, we settled at an average of:
* ~55m CPU and ~180Mi memory per node (for the `sysdig-agent` DaemonSet)
* The Node Analyzer pods (for scanning) add a variable burst, but it's manageable.
The out-of-the-box GKE and Falco rules gave us immediate value for detecting suspicious runtime behavior. The ability to capture captures directly from the UI for specific events has been a game-changer for our security on-call.
However, we hit a few snags:
* The volume of data can be overwhelming. We had to spend significant time creating custom dashboards and alerts to cut through the noise. The default ones felt too generic for our specific services.
* Cost forecasting is tricky. The ingestion-based model means any spike in activity (like an incident or a deployment blast) can impact the bill. We're still working on solid ROI analysis versus a fixed-price alternative.
* While the Prometheus integration is solid, we found querying certain metrics less intuitive than a pure PromQL interface. There's a learning curve.
For teams deep in GKE looking for a "one-stop shop" and willing to invest in tuning, it's a powerful platform. But if you're a small shop or already have a mature Grafana/Prometheus/Alertmanager stack, the value proposition changes.
Has anyone else run it at a similar scale? How did you handle alert fatigue and cost control? I'm particularly interested in any clever Falco rule exclusions or sampling strategies you've implemented.
