Collect metrics

edit

When collecting metrics, please note that the DoubleValueRecorder and LongValueRecorder metrics are not yet supported.

Here’s an example of how to capture business metrics from a Java application.

// initialize metric
Meter meter = GlobalMetricsProvider.getMeter("my-frontend");
DoubleCounter orderValueCounter = meter.doubleCounterBuilder("order_value").build();

public void createOrder(HttpServletRequest request) {

   // create order in the database
   ...
   // increment business metrics for monitoring
   orderValueCounter.add(orderPrice);
}

See the Open Telemetry Metrics API for more information.

Verify OpenTelemetry metrics data
edit

Use Discover to validate that metrics are successfully reported to Kibana.

  1. Launch Kibana:

    1. Log in to your Elastic Cloud account.
    2. Navigate to the Kibana endpoint in your deployment.
  2. Open the main menu, then click Discover.
  3. Select apm-* as your index pattern.
  4. Filter the data to only show documents with metrics: [data_stream][type]: "metrics"
  5. Narrow your search with a known OpenTelemetry field. For example, if you have an order_value field, add order_value: * to your search to return only OpenTelemetry metrics documents.
Visualize in Kibana
edit

Use Lens to create visualizations for OpenTelemetry metrics. Lens enables you to build visualizations by dragging and dropping data fields. It makes smart visualization suggestions for your data, allowing you to switch between visualization types.

For more information on using Lens, refer to the Lens documentation.
