I have reported some custom metrics through "openTeletemtry". I would like to be able to customize the data charts in the "metrics" module within "APM".Or is there another way to generate different graphs by different "service.name"?  
I see "go pprof" data when I use "[go.elastic.co/apm](http://go.elastic.co/apm)" to report data, which module in "APM" can I see this information?

You cannot currently customise the Metrics panel. You can use Lens instead. I'll demonstrate how you can do that.

Say for example your application reports a metric called `ex.com.one`, like in the opentelemetry-go getting started guide: [Getting Started | OpenTelemetry](https://opentelemetry.io/docs/go/getting-started/#creating-metric-instruments). These metrics will be written to indices matching the pattern `apm-*-metric-*`, and will look something like this:

```json
{
  "_index": "apm-8.0.0-metric-000001",
  "_id": "I_VB8HoBV8NbQ8CgPGVv",
  "_score": 1,
  "_source": {
    "agent": {
      "name": "opentelemetry/go",
      "version": "1.0.0-RC1"
    },
    "processor": {
      "name": "metric",
      "event": "metric"
    },
    "metricset.name": "app",
    "observer": {
      "hostname": "goat",
      "id": "152d9100-2793-4c91-8de2-6314be9e1783",
      "ephemeral_id": "1d233a8e-fbb4-4bac-a2b3-9abd45aae8a5",
      "type": "apm-server",
      "version": "8.0.0",
      "version_major": 8
    },
    "@timestamp": "2021-07-29T03:14:04.030Z",
    "ex.com.one": 1,
    "ecs": {
      "version": "1.10.0"
    },
    "service": {
      "name": "unknown_service_otel-collector",
      "language": {
        "name": "go"
      }
    },
    "event": {
      "ingested": "2021-07-29T03:14:05.038237154Z"
    }
  }
}

```

You can find these documents in Discover in Kibana, and find the metric field you are interested in visualising:

When you click Visualize, you will be taken to the Lens app. You can then set "Break down by" to the `service.name` field:

The APM UI does not currently support visualising pprof data.
