Can you help me how to add namespace label to Open Telemetry logs ?
To add a namespace label to OpenTelemetry logs in a Kubernetes environment, you can use the k8sattributesprocessor
in your OpenTelemetry Collector configuration. This processor can automatically add Kubernetes metadata, such as the namespace, to your logs.
Here's a general approach to achieve this:
-
Configure the OpenTelemetry Collector: Ensure your OpenTelemetry Collector is set up to receive logs from your application. You can use the
filelog
receiver if you're collecting logs from files, or another appropriate receiver based on your setup. -
Add the
k8sattributesprocessor
: This processor enriches your telemetry data with Kubernetes metadata. You can configure it to add thek8s.namespace.name
attribute to your logs. -
Example Configuration: ```yaml receivers: filelog: include: ["/var/log/containers/*.log"] start_at: beginning
processors: k8sattributes: auth_type: serviceAccount passthrough: false
exporters: loki: endpoint: "https://loki.example.com/loki/api/v1/push" auth: authenticator: basicauth/logsService
service: pipelines: logs: receivers: [filelog] processors: [k8sattributes] exporters: [loki] ```
-
Deploy the Collector: Apply this configuration to your OpenTelemetry Collector deployment in Kubernetes.
-
Verify the Logs: Check your logs in Loki or your chosen log storage solution to ensure the
k8s.namespace.name
attribute is present.
This setup will automatically add the namespace information to your logs, making it easier to filter and analyze them based on the Kubernetes namespace.

Can you provide detailed configuration for this with k8s-monitoring-helm Helm Chart?
To add the k8s.namespace.name
label to your OpenTelemetry logs using the k8s-monitoring-helm
Helm chart, you can follow these steps to configure the OpenTelemetry Collector:
-
Install the Helm Chart: Ensure you have the
k8s-monitoring-helm
chart installed in your Kubernetes cluster. You can find the chart and installation instructions in the Grafana documentation or the Helm repository. -
Modify the Helm Values: You will need to customize the Helm values to include the
k8sattributesprocessor
in your OpenTelemetry Collector configuration. Here is an example of how you might configure it:
otelCollector: config: receivers: filelog: include: - /var/log/pods/*/*/*.log start_at: beginning include_file_path: true include_file_name: false
processors: k8sattributes: auth_type: serviceAccount passthrough: false exporters: loki: endpoint: "https://loki.example.com/loki/api/v1/push" auth: authenticator: basicauth/logsService service: pipelines: logs: receivers: [filelog] processors: [k8sattributes] exporters: [loki]
-
Deploy the Configuration: Apply the modified Helm values to your Helm release. This will update the OpenTelemetry Collector deployment with the new configuration.
-
Verify the Logs: Once deployed, check your logs in Loki or your chosen log storage solution to ensure the
k8s.namespace.name
attribute is present.
This configuration uses the filelog
receiver to collect logs from the default Kubernetes log location and the k8sattributes
processor to enrich the logs with Kubernetes metadata, including the namespace name. The logs are then exported to Loki.
