TODO Grafana and logs
182+
During scale tests, operators can monitor progress using a Grafana dashboard.
183+
Coder offers a comprehensive overview
184+
[dashboard](https://github.com/coder/coder/blob/main/scaletest/scaletest_dashboard.json)
185+
that can seamlessly integrate into the internal Grafana deployment.
186+
187+
This dashboard provides insights into various aspects, including:
188+
189+
- Utilization of resources within the Coder control plane (CPU, memory, pods)
190+
- Database performance metrics (CPU, memory, I/O, connections, queries)
191+
- Coderd API performance (requests, latency, error rate)
192+
- Resource consumption within Coder workspaces (CPU, memory, network usage)
193+
- Internal metrics related to provisioner jobs
194+
195+
It is highly recommended to deploy a solution for centralized log collection and
196+
aggregation. The presence of error logs may indicate an underscaled deployment
197+
of Coder, necessitating action from operators.
