Prometheus.GCCollector(; registry=DEFAULT_REGISTRY) |
|
|
|
Create a collector that exports metrics about allocations and garbage collection. |
|
|
|
**Keyword arguments** |
|
- `registry :: Prometheus.CollectorRegistry`: the registry in which to register the |
|
collector. The default registry is used by default. Pass `registry = nothing` to skip |
|
registration. |
|
|
|
!!! note |
|
A `GCCollector` is registered automatically with the default registry. |
|
If necessary it can be removed by calling |
|
```julia |
|
Prometheus.unregister(Prometheus.DEFAULT_REGISTRY, Prometheus.GC_COLLECTOR) |
|
