# Monitoring

Tarmac exposes several metrics to facilitate monitoring services. Metrics are available via the `/metrics` end-point in the Prometheus format.

These metrics include internal Tarmac system metrics such as the number of goroutines, memory utilization, and WASM function-specific metrics such as counters for Callbacks and WASM function execution time.

Some valuable metrics to monitor are in the below table.

| Metric Name       | Metric Type | Description                                                     |
| ----------------- | ----------- | --------------------------------------------------------------- |
| `http_server`     | Summary     | Summary of HTTP Server requests                                 |
| `scheduled_tasks` | Summary     | Summary of user defined scheduled task WASM function executions |
| `wasm_callbacks`  | Summary     | Summary of Tarmac callback function executions                  |
| `wasm_functions`  | Summary     | Summary of wasm function executions                             |

These metrics do not need to be enabled and are "on by default".
