Netobserv allows you to capture flows, packets and metrics from your cluster.
Find more information at: https://github.com/netobserv/network-observability-cli/


Syntax: netobserv [flows|packets|metrics|follow|stop|copy|cleanup|version] [options]


main commands:
  flows      Capture flows information in JSON format using collector pod.
  metrics    Capture metrics information in Prometheus using a ServiceMonitor (OCP cluster only).
  packets    Capture packets information in pcap format using collector pod.


extra commands:
  cleanup    Remove netobserv components and configurations.
  copy       Copy collector generated files locally.
  follow     Follow collector logs when running in background.
  stop       Stop collection by removing agent daemonset.
  version    Print software version.


basic examples:
  netobserv flows --drops                                     # Capture dropped flows on all nodes
  netobserv flows --query='SrcK8S_Namespace=~"app-.*"'        # Capture flows from any namespace starting by app-
  netobserv packets --port=8080                               # Capture packets on port 8080
  netobserv metrics --enable_all                              # Capture default cluster metrics including packet drop, dns, rtt, network events packet translation and UDN mapping features informations


advanced examples:
  Capture flows in background and copy output locally
    netobserv flows --background \                            # Capture flows using background mode
    --max-time=15m \                                          # for a maximum of 15 minutes
    --protocol=TCP --port=8080 \                              # either on TCP 8080
    or --protocol=UDP                                         # or UDP
    netobserv follow                                          # Display the progression of the background capture
    netobserv stop                                            # Stop the background capture by deleting eBPF agents
    netobserv copy                                            # Copy the background capture output data
    netobserv cleanup                                         # Cleanup netobserv CLI by removing the remaining collector pod


  Capture flows from a specific pod
    netobserv flows                                           # Capture flows
    --node-selector=kubernetes.io/hostname:my-node            # on node matching label 'kubernetes.io/hostname=my-node'
    --query='SrcK8S_Name=~".*my-pod.*"                        # from any pod name containing 'my-pod'
             or DstK8S_Name=~".*my-pod.*"'                    # or to any pod name containing 'my-pod'


  Capture packets on specific nodes and port
    netobserv packets                                         # Capture packets
    --node-selector=netobserv:true \                          # on nodes labelled with 'netobserv=true'
    --port=80 \                                               # on port 80 only
    --max-bytes=100000000                                     # for a maximum of 100MB


  Capture node and namespace drop metrics
    netobserv metrics \                                       # Capture metrics
    --drops                                                   # including drops
    --include_list=node,namespace                             # for all metrics matching 'node' or 'namespace' keywords


  Capture metrics in background
    netobserv metrics --background \                          # Capture metrics using background mode
    --max-time=24h                                            # for a maximum of 24 hours
