View Source Monitoring

Please read the Ash monitoring guide 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

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

 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.
