#1017 Newbie question. How to troubleshoot with Wireshark?

Jeff Bergstedt Fri 4 Nov 2022

  1. I am new to Project Haystack, so forgive me if this is a dumb question. I did try to search the forums.

I understand about the tagging, but I also understand that Haystack is a protocol that would allow say for example, a Siemens Desigo Optic system to communicate to a Tridium Niagara N4 Jace.

Lets say I want to run Wireshark and see what Desigo Optic is doing to the Jace. I looked through Wireshark's enabled protocols and I do not see anything to decode Haystack or Project Haystack. I have Googled "Haystack Wireshark" and not found anything of use.

Hi Jeff,

Haystack communicates through HTTP (or HTTPS), see also https://project-haystack.org/doc/lib-phIct/haystack, so you can simply use that protocol to read the communication using Wireshark.

Please let me know if you have any further questions.

Just as Chris says - its just simple request/response over HTTP so easy to debug. The payload is most often encoded as JSON or Zinc. The protocol itself is described here

In Wireshark you see that is is encoded like (text/zinc). What I do is check the api just in a browser. like this Then you directly what is availble.
