Monitoring Tarmac with Prometheus Metrics
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 |

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