- `coder_workspacetraffic.sh`: Runs traffic generation against the loadtest cluster and creates
a monitoring manifest for the traffic generation pod. This pod will restart automatically
after the traffic generation has completed.

## Grafana Dashboard

A sample Grafana dashboard is provided in `scaletest_dashboard.json`. This dashboard is intended
to be imported into an existing Grafana instance. It provides a number of useful metrics:

- **Control Plane Resources**: CPU, memory, and network usage for the Coder deployment, as well as the number of pod restarts.
- **Database**: Rows inserted/updated/deleted/returned, active connections, and transactions per second. Fine-grained `sqlQuerier` metrics are provided for Coder's database as well, broken down my query method.
- **HTTP requests**: Number of HTTP requests per second, broken down by status code and path.
- **Workspace Resources**: CPU, memory, and network usage for all workspaces.
- **Workspace Agents**: Workspace agent network usage, connection latency, and number of active connections.
- **Workspace Traffic**: Statistics related to workspace traffic generation.
- **Internals**: Provisioner job timings, concurrency, workspace builds, and AuthZ duration.

A subset of these metrics may be useful for a production deployment, but some are only useful
for load testing.

> **Note:** in particular, `sqlQuerier` metrics produce a large number of time series and may cause
> increased charges in your metrics provider.
