        i think there is something on telegraf

        Suricata is certainly spewing stats out through the socket, so that part is working. I agree it is likely on the telegraf side. I'm not familiar with telegraf having never used it. Are there some debugging options to have telegraf log someplace the raw data it is getting from the socket?

        Here is the original Feature Request: https://redmine.pfsense.org/issues/10421#change-47203. The creator of the request claimed to have it working (although he had to manually edit the suricata.yaml file). I duplicated in the PHP code what he did on the Suricata side.

        EDIT: never mind, just realized you were the creator of the Feature Request ... ☺

          yes, i was the one requesting it, it was working at that time, maybe it was before the upgrade to freebsd 12.1-stable

          as you can see there is a

          read(9,"{"timestamp":"2020-07-15T18:40:1"...,10420224)

          that's part of the output from suricata

          followed by

          read(9,0xc00095a000,10412032)                    ERR#35 'Resource temporarily unavailable'

          well, i have no idea, i also tried with Telegraf 1.15.0 but same error/problem

            FYI. As of today (Thursday, July 16th), barring no major issues showing up the DEVEL branch, the plan is to migrate this 5.0.3 Suricata package update over to pfSense-2.4.5_p1 RELEASE Monday or Tuesday of next week (July 20th or 21st).

              @bmeeks maybe i found something,
              the suricata plugin of telegraf is expecting \n at the end of the line but i think it's never coming,
              it seems to be truncated at the end
              any settings from suricata that can solve this?

              example coming from unix socket

              {"timestamp":"2020-07-17T10:08:18.856758+0200" ......."invalid_checksum":0,"no_flow":0,"syn":1044,"synack":454,"r <- alway end like this

              example coming from eve.json

              {"timestamp":"2020-07-17T10:35:00.974605+0200".......<{"expectations":0},"flow":{"memuse":8443384}}}}}  <--- good output

                  Ah-ha! It was truncating the stream. FreeBSD has so darn many system tunables ... 😕

                    Added a section to my initial RELEASE NOTES post detailing the need to check and probably adjust these system tuneables. Thanks for the investigation and feedback!
