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.

Visualize in Kibanaedit

TSVB within Kibana is the recommended visualization for OpenTelemetry metrics. TSVB is a time series data visualizer that allows you to use the Elasticsearch aggregation framework’s full power. With TSVB, you can combine an infinite number of aggregations to display complex data.

In this example eCommerce OpenTelemetry dashboard, there are four visualizations: sales, order count, product cache, and system load. The dashboard provides us with business KPI metrics, along with performance-related metrics.

Let’s look at how this dashboard was created, specifically the Sales USD and System load visualizations.
