Major Changes

• #2217
  7ac1d3c
  Thanks @EmrysMyrddin! - Adds a cache for metrics definition
  (Summary, Histogram and Counter).

  Fixes an issue preventing this plugin to be initialized multiple times, leading to metrics
  duplication error (ardatan/graphql-mesh#6545).

  Behavior Breaking Change:

  Due to Prometheus client API limitations, a metric is only defined once for a given registry. This
  means that if the configuration of the metrics, it will be silently ignored on plugin
  re-initialization.

  This is to avoid potential loss of metrics data produced between the plugin re-initialization and
  the last pull by the prometheus agent.

  If you need to be sure metrics configuration is up to date after a plugin re-initialization, you
  can either:

  • restart the whole node process instead of just recreating a graphql server at runtime
  • clear the registry using registry.clear() before plugin re-initialization:

    function usePrometheusWithReset() {
      registry.clear()
      return usePrometheus({ ... })
    }

  • use a new registry for each plugin instance:

    function usePrometheusWithRegistry() {
      const registry = new Registry()
      return usePrometheus({
        registry,
        ...
      })
    }

  Keep in mind that this implies potential data loss in pull mode.

  API Breaking Change:

  To ensure metrics from being registered multiple times on the same registry, the signature of
  createHistogram, createSummary and createCounter have been changed to now include the
  registry as a mandatory parameter.

  If you were customizing metrics parameters, you will need to update the metric definitions

  usePrometheus({
    execute: createHistogram({
  +   registry: registry
      histogram: new Histogram({
        name: 'my_custom_name',
        help: 'HELP ME',
        labelNames: ['opText'] as const,
  -     registers: [registry],
      }),
      fillLabelsFn: () => {}
    }),
    requestCount: createCounter({
  +   registry: registry
      histogram: new Histogram({
        name: 'my_custom_name',
        help: 'HELP ME',
        labelNames: ['opText'] as const,
  -     registers: [registry],
      }),
      fillLabelsFn: () => {}
    }),
    requestSummary: createSummary({
  +   registry: registry
      histogram: new Histogram({
        name: 'my_custom_name',
        help: 'HELP ME',
        labelNames: ['opText'] as const,
  -     registers: [registry],
      }),
      fillLabelsFn: () => {}
    }),
  })
