In the application context, network errors are often reduced to simple timeout or other errors, but Wireshark provides a direct view into what is happening on the network layer and often provides an explanation for errors or unexpected behavior we see in Ignition.īecause of Wireshark's microscopic level of detail, it's often most appropriate to use Wireshark after initially troubleshooting at the Ignition level. if the device is receiving data from Ignition, but not responding.if Ignition's requests are being received by the device.Wireshark is a tool use for granular analysis of network traffic, so it is generally used when other methods of troubleshooting fail to provide enough information, or give errors that are too vague to be able to meaningfully understand exactly what is happening.įor example, if Ignition is reporting a timeout to another device, Wireshark may be able to tell us more information about: It is completely free to use and is available for MacOS, Windows, Linux, and other Operating Systems. Wireshark is a very popular tool and is used in personal, commercial, and government enterprises. This data can then be saved to a file to be shared with others. Wireshark "sniffs" these packets by collecting all of the incoming and outgoing data on the machine that it's installed on and displaying it in a clear way for analysis by the user. When devices communicate with each other over a network, this data is broken up into strictly structured "packets" which are then most commonly sent through the Wi-Fi or Ethernet channels that make up the network. Wireshark is an open-source packet sniffing program which collects, displays, and organizes network traffic. With this knowledge, the reader should be able to troubleshoot and assist Support in troubleshooting issues involving connectivity between Ignition and its various peripherals. This article is intended to give readers a strong foundational knowledge of using Wireshark to troubleshoot network-related issues with regards to Ignition.
