meshctl hubble observe

Gain visibility into network and app protocol flows, such as individual TCP connections, DNS queries, or HTTP requests.

Synopsis

The command extends the visibility that is provided by standard Kubernetes commands and the Cilium dashboard. It allows you to monitor and observe traffic to, from, and between workloads in your cluster. You can use this information to determine whether network policies were accurately applied and to confirm that requests are properly forwarded and dropped.

Unlike the Hubble CLI, the meshctl hubble observe command does not require you to port forward the Hubble relay service on each cluster that you want to target. Instead, you can simply run the command against the cluster and workloads that you are interested in.

  meshctl hubble observe [flags]

Examples 

  meshctl hubble observe --since=5m --all

Options 

        --all              View flow logs for all workloads across all namespaces. Note that this command might return an extensive amount of data. Use the filter options to reduce the amount of data that is returned.
      --cluster string   Filter flows by cluster name
      --first uint32     Get the first N flows that were observed.
  -f, --follow           Follow the flows as they are observed.
  -h, --help             help for observe
      --last uint32      Get the last N flows that were observed (default 20).
      --since string     Filter flows since a specific date. The format is relative (e.g. 3s, 4m, 1h43,, ...) or one of:
