Telegraf for ARM systems? (e.g. Netgate SG-3100).

victorhooi

Hi,

I have quite a few SG-3100 unit we bought, and I'd love to get Telegraf working on them.

There was this Github PR before:

https://github.com/pfsense/FreeBSD-ports/pull/627

However, I believe that might have been blocked on this FreeBSD bug regarding Go on ARM. However, that bug is fixed.

Then I noticed this commit that seems to enable ARMv7 anyhow.

But when I refreshed packages on my SG-3100, Telegraf doesn't show up.

Is there something I can do to make it show up? Or are we still waiting on something that pushes from pfsense/FreeBSD-ports to actual packages?

Like @rbgarga said there in the pull request there are additional problems building it using our current builder setup. It will require further changes.

Is it possible to get an idea from Netgate on how difficult it is to fix the Telegraf issues on ARM boxes?

We have quite a few XG-7100's deployed - but we also use SG-3100's for many of our lab rooms.

This is causing issues, as we can't pull the metrics we need via Telegraf.

We do have a few spare Qotom Intel i5 boxes from before we started buying up Netgate gear, which I've been asked to in the meantime. Cheap and will do for now.

I'm keen to stick with Netgate gear if possible, and support the project - but there doesn't seem to be anything in the sub $500 price range that would actually work with Telegraf.

Is there anything else you can suggest to get Telegraf working on our ARM-based SG-3100's?

Thank you!

Is there any update on getting Telegraf working on Netgate's ARM devices?

Is this something that will be fixed in pfSense 2.5?

Or will it be fixed in pfSense 2.4.x?

It requires a native ARMv6/7 build environment for the GO Telegraf client and currently we are cross-building those packages.
There are now a number of things that will require native builders and work is underway to add those, initially for ARM64.

There is no ETA though as far as I know.

Is there any update on this please? =)

Will we see packages like Telegraf working again on Netgate ARM devices soon?

I recently upgraded one of our SG-3100 units to pfSense 2.5.0 (Build from January 1, 2019).

However, Telegraf still does not appear to be available in the list of packages.

Is there any idea of when it might be available for ARM-based Netgate devices again?

stephenw10

Our ARM64 build server is now up and running but it looks like it's not yet building Telegraf/Rust etc. I'll see if there's a reason for that.
No news on ARMv6/7 though.

Any update on whether Telegraf packages are available for Netgate ARM devices (e.g. SG-3100) yet?

stephenw10

Telegraf is not available for armv6 (SG-3100) for the same reason. It requires a native build because of the language chosen to write it in. We do not currently have any armv6 build hardware so cannot build the package.

Ah ok - so the build pipeline for Rust/Golang is still not working for the SG-1100/SG-3100 etc, right?

Do you know if this is likely to be fixed in the future?

It would be a real bummer if all the SG-1100 and SG-3100 units out there were no longer able to run anything written in Rust or Golang =(.

stephenw10

The SG-1100 is aarch64 and we do have build hardware for that which is why it has Suricata 5.

I believe that should allow Telegraph there unless there is another obstacle I'm unaware of (which I might be).

Steve

Aha got it - but the SG-3100 is ARMv6/7, right, so that is still pending?

Basically, we have around 10 x SG-3100's - and we'd like to get Telegraf (Golang), Suricata (Rust) etc. all working on it.

Do you know if getting working build support for SG-3100 is on the roadmap?

Or if the SG-3100 isn't being supported anymore - is there a replacement device on the roadmap? (Although it'd be a bummer if the SG-3100 is being EOLed, since we bought them only last year).

stephenw10

Telegraf is now available on the SG-1100. Please test it if you can.

We are working on what we can do on armv6.

I just installed the package on my SG-1100 and in the System Log I get

Apr 1 00:30:46 kernel pid 72858 (telegraf), jid 0, uid 0: exited on signal 4 (core dumped)

and when I try and run telegraf from the console I get

Illegal instruction (core dumped)

stephenw10

Thanks for the report, we are investigating.

I have a SG-1100 and getting the same results, signal 4 (core dump).

stephenw10

It is still being looked at but is much lower priority than some other things right now.

I can confirm it compiles and runs on SG-3100 with the following flags when using telegraf's master and go 1.14.1:

CGO_ENABLED=0 GOOS=freebsd GOARCH=arm GOARM=7 go build ./cmd/telegraf

I'm downloading the ports repository now to try and make the package.

@stephenw10 I installed the latest Telegraf 0.9_3 package on my SG-1100 today. I'm on pfSense 2.4.5. When I try to start the service I get a continuous stream of core dumps in the system log.

Apr 19 19:36:18 kernel pid 29205 (telegraf), jid 0, uid 0: exited on signal 4 (core dumped)
Apr 19 19:36:21 kernel pid 29379 (telegraf), jid 0, uid 0: exited on signal 4 (core dumped)
Apr 19 19:36:25 kernel pid 29647 (telegraf), jid 0, uid 0: exited on signal 4 (core dumped)
