Visualize a Counter from MicroMeter with ElasticAPM

Elastic Observability APM

Im trying out a simple counter with MicroMeter. I have 4 instances of the same application running on k8s and each of them has a counter "counter-example" which they increment.

From what I understand, each increment creates a new document with the new incremented value. This is done for each pod.

Now I want to sum all 4 "counter-example" last values into 1 total value across all instances in a dashboard.

I keep failing as I can't seem to figure out how to do a group-by on last-value and then sum the result.

We do not capture counter increments, rather we report counter values periodically based on the metrics_interval config - see more in the Micrometer documentation.

Metric docs should contain a service.node.name filed, which should be set with the container ID in the case of k8s. So, combining your search for both service.name and service.node.name should address your needs.

Combining the search on both service.name and service.node.node will give me 4 distinct values right? Each showing the last value of each of the corresponding counters.

In Kibina, I select a TSVB visualization, pick a Table. Here I seem to be able to select the aggregation max for my counter example-counter. This will only show 1 out of the 4 counters I have and there doesnt seem to be a way to sum all 4 counters grouping them by each pod.
