The LinkRunner AT Network AutoTester offers user-configured AutoTests for a wide range of tasks. This network tester’s cable test and switch identification facilitate problem isolation. The device is supported by netAlly after NETSCOUT divested its handheld troubleshooting devices in 2018. The LinkRunner device replaces the former and now obsolete OneTouch AT network troubleshooting technology acquired from Seattle-based Fluke Networks by NETSCOUT in 2015.

Wireshark is a free and open source network troubleshooting tool.
All network administrators would be able to find a use for this tool in their environment. It allows people from outside of the networking industry to capture data required for a quick diagnosis. Things that typically would require me to be onsite for diagnosis can now be handed to Tier 1 techs for data collection and reporting. Since moving toward cable certification, we've experienced an almost unbelievably low level of cable failure. When it does happen, though, there is no guessing. Our Fluke units tell us what the problem is and where.
I don't know of any other tool that works as well as Wireshark for packet capture an inspection. It's extremely easy to get up and running, and even with little to no knowledge of how to use the tool, you can be looking at all the traffic coming off a network interface.
A more user-friendly interface would be nice, but then again it is not really designed for those who are not quite comfortable with this type of software.
Changes to functionality on updates - this can sometimes happen unexpectedly and can be an annoyance.
It's very simple and easy to use, although individuals not used to managing and administering networks would take some time to get familiar with it. Once they have mastered use of the application, it's easy to stay knowledgeable about it, iteration after iteration. It is well supported online through an open-source community network of professionals who are helpful in imparting knowledge and in providing assistance.
I don't believe Wireshark has "true" support as the software is open source. However, there is an active & friendly community around Wireshark that are more than happy to help answer questions. From a comprehensive Wiki and FAQ section on the site to the Ask a Question forum and bug tracker section, there's plenty of support options to make sure your questions and issues are addressed.
There is little to no competition in this field. If you need to do any type of advanced network monitoring/identification (or use 10G) then you're going to own a Fluke. While Ideal does have a couple of devices that appear to be the closest competitor, the differences are still extremely evident.
Wireshark is a free tool that came highly recommended by one of our former network security consultants. Using the tool he was able to resolve all of our higher tier network tickets, so we observed first hand why we needed to add Wireshark into our toolset. We received in-depth instruction and training scenarios that demonstrated the effectiveness and power of the product, so we didn't spend any time reviewing competing products.
The certainty coming from the diagnostic process with the Fluke leads to less guessing and quicker fixes.
With multiple departments involved in the process of connecting devices to the network, the Fluke helps us to quickly certify a switch closet worth of cable and create error free documentation.
