# Monitoring
Please read [the Ash monitoring guide](https://hexdocs.pm/ash/monitoring.html) for more information. Here we simply cover the additional traces & telemetry events that we publish from this extension.
A tracer can be configured in the api. It will fallback to the global tracer configuration `config :ash, :tracer, Tracer`
```elixir
graphql do
trace MyApp.Tracer
end
```
## Traces
Each graphql resolver, and batch resolution of the underlying data loader, will produce a span with an appropriate name. We also set a `source: :graphql` metadata if you want to filter them out or annotate them in some way.
## Telemetry
AshGraphql emits the following telemetry events, suffixed with `:start` and `:stop`. Start events have `system_time` measurements, and stop events have `system_time` and `duration` measurements. All times will be in the native time unit.
- `[:ash, <api_short_name>, :gql_mutation]` - The execution of a mutation. Use `resource_short_name` and `mutation` (or `action`) metadata to break down measurements.
- `[:ash, <api_short_name>, :gql_query]` - The execution of a mutation. Use `resource_short_name` and `query` (or `action`) metadata to break down measurements.
- `[:ash, <api_short_name>, :gql_relationship]` - The resolution of a relationship. Use `resource_short_name` and `relationship` metadata to break down measurements.
- `[:ash, <api_short_name>, :gql_calculation]` - The resolution of a calculation. Use `resource_short_name` and `calculation` metadata to break down measurements.
- `[:ash, <api_short_name>, :gql_relationship_batch]` - The resolution of a batch of relationships by the data loader. Use `resource_short_name` and `relationship` metadata to break down measurements.
- `[:ash, <api_short_name>, :gql_calculation_batch]` - The resolution of a batch of calculations by the data loader. Use `resource_short_name` and `calculation` metadata to break down measurements.
