It can be useful for monitoring and debugging purpose.
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:
