Our Kubernetes API was suddenly taking 20 seconds to respond, but traditional pod metrics showed healthy CPU and memory. I needed true observability to find the root cause without rewriting code or paying Datadog's $0.05 per custom metric surcharge.
I chose SigNoz for a unified metrics, logs, and traces backend, and the OpenTelemetry Operator to auto-instrument our cluster.
The Setup
First, I installed SigNoz directly into our cluster using Helm:
helm repo add signoz https://charts.signoz.io
