      Diagnostic Tools

      This article details the diagnostic tools Panzura provides, where to find them and how to use them.

      Panzura provides the following tools to assist with troubleshooting CloudFS:

      • Packet capture tools: Capture packets on the Ethernet ports. You can select to capture all packets or restrict the capture to TCP or UDP packets. The captured packets are saved into a file that you can download and send to Technical Support.
      • Diagnostic tools: Execute network, node‐specific, and cloud diagnostic commands.
      • Performance test tools: Execute Iperf commands to test network performance.

      To use the node's troubleshooting tools, navigate to the following page:

      Maintenance > Diagnostics

      The following table describes the node's diagnostic tools sections Packet Capture and Diagnostic Tools.

      Packet Capture Option Description
      Packet Capture Tools
      Capture type 1

      Capture selected headers and packets.

      • pkt-capture – Capture TCP and UDP headers and packet.
