apiMetrics not working (nest v8)

All the apiMetrics aren’t showing up in the metrics page, only the default system ones are.

Using the basic snippet.

OpenTelemetryModule.forRoot({
      metrics: {
        hostMetrics: true, // Includes Host Metrics
        defaultMetrics: true, // Includes Default Metrics
        apiMetrics: {
          enable: true, // Includes api metrics
          // timeBuckets: [], // You can change the default time buckets
        },
        defaultLabels: {
          app: process.env.npm_package_name,
          version: process.env.npm_package_version,
        },
      },
    }),

if I only have apiMetrics enabled, I get:

# no registered metrics

as the metrics response. I have no idea how, but one in around 500 tries I saw for a second the needed metrics, but can’t reproduce - so in general, it doesn’t work.

Released in 2.5.0. defaultLabels is available inside apiMetrics property. Some metric plugins don’t allow custom labels yet.

@pragmaticivan My bad! I didnt await the otelSDK.start() in the main.ts.

I’ll hijack this issue for another issue. the defaultLabels parameter for the opentelemetryModule doesn’t work - it just ignores what I pass in.
