# Metrics

Kubeshark provides metrics from `worker` components.
It can be useful for monitoring and debugging purpose.

## Configuration

By default, Kubeshark uses port `49100` to expose metrics via service `kubeshark-worker-metrics`.

In case you use [kube-prometheus-stack] (https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack) community Helm chart, additional scrape configuration for Kubeshark worker metrics endpoint can be configured with values:

```
prometheus:
  enabled: true
  prometheusSpec:
    additionalScrapeConfigs: |
      - job_name: 'kubeshark-worker-metrics'
        kubernetes_sd_configs:
          - role: endpoints
        relabel_configs:
          - source_labels: [__meta_kubernetes_pod_name]
            target_label: pod
          - source_labels: [__meta_kubernetes_pod_node_name]
            target_label: node
          - source_labels: [__meta_kubernetes_endpoint_port_name]
            action: keep
            regex: ^metrics$
          - source_labels: [__address__, __meta_kubernetes_endpoint_port_number]
            action: replace
            regex: ([^:]+)(?::\d+)?
            replacement: $1:49100
            target_label: __address__
          - action: labelmap
            regex: __meta_kubernetes_service_label_(.+)
```
