APM using OpenTelemetry Collector with Kubernetes APM using OpenTelemetry Collector with Kubernetes

Last Updated: Mar. 14, 2024

Coralogix now offers features of application performance monitoring (APM) for modern, cloud-native environments for those customers using OpenTelemetry collector with a Kubernetes processor. Our new features decorate all pillars of observability with additional information that extends beyond system availability, service performance, and response times.

Installation & Configuration

Install and configure OpenTelemetry for Kubernetes to send your telemetry data to Coralogix. We strongly recommend configuring Otel to send Coralogix your logs, metrics, and traces, so that you can enjoy the highest quality APM and correlate your data.

APM on Your Coralogix Dashboard

Access our APM features on your Coralogix dashboard

STEP 1. In your Coralogix dashboard, click on the Explore tab > Tracing. Then click on the trace of interest.

apm choose trace

STEP 2. Click on POD and HOST features, in addition to RELATED LOGS and SPAN LOGS. View them in either SPANS VIEW or DEPENDENCIES VIEW.

apm view pod and host


Validate your configuration by taking the following steps. If any of the queries below return empty or invalid results, review the data being sent.

K8s Resource Attributes and Trace Spans

To match Prometheus or OpenTelemetry metrics with trace spans, it is necessary to ship valid K8s Resource Attributes from OpenTelemetry.

Here is an example of K8s Resource Attributes associated with a span from the Coralogix Tracing UI.

Our APM backend will check for both the k8s.pod.name and k8s.node.name attributes and correlate them with metrics and logs. If these values are not set or are missing, the APM process will not function correctly.

Host Metrics (Prometheus)

There are specific metrics that are required when correlating data for APM. When using Prometheus, metrics from the Kube State Metrics (KSM) and the Node Exporter are required. Note that both are included when installing the Coralogix Prometheus Operator.

Validate the Kube State Metrics (KSM)

To verify KSM metrics are being received, run a query via the Coralogix Grafana console to validate that KSM metric labels match the k8s.node.name attribute described in our OpenTelemetry span:

kube_node_info{node="<your node name>"}

Validate Node Exporter Metrics

The PromQL query from the previous step will return the internal_ip label. Use this value to verify that you are receiving node exporter metrics for the relevant node or host:

count(node_cpu_seconds_total{instance=~"<internal_ip>.+"}) by (instance)

Validate Pod Metrics

To verify that pod metrics are being received from KSM, run the following query in Grafana:


Use the following queries to confirm that you are receiving pod metrics in the correct format:
