node_exporter command line flags

None, the defaults for 0.16 match my needs

Are you running node_exporter in Docker?

No

What did you do that produced an error?

Just ran it for a couple of days

What did you expect to see?

It not to crash

What did you see instead?

I have the same issue as @daenney

node_exporter version: output of node_exporter --version

node_exporter, version 0.16.0-rc.0 (branch: HEAD, revision: 002c1ca02917406cbecc457162e2bdb1f29c2f49)

Observation: I have node_exporter installed on 6 machines at this point. The two machines it keeps failing on are the only two vms I am currently using. The others are bare metal and are running great.

[brian-brazil]

If it's reproducible, could you try bisecting which collectors are enabled to see which it is?

[SuperQ]

Also, running with debug level logs would help identify if there is a specific collector problem.

[daenney]

@mschroeder223 That's interesting. In my case the machine it blows up on is bare metal.

I've set systemd to restart the node_exporter for now, but looking at the logs a new error surfaced too: Mar 30 09:15:14 endor systemd[1]: node_exporter.service: Main process exited, code=killed, status=5/TRAP. Unsure what that's about.

I've updated my unit file to run with debug logs, I'll check in on it in 24 hours, see what gives.

[mschroeder223]

It took about 4.5hrs for it to crash this morning, this is the output that was captured https://gist.github.com/mschroeder223/16e48f64a8b17888eae0e1d597a83504

I do see several collectors which are running and do not need to be enabled so I am going to disable them and see if it makes any difference.

[grobie]

There is quite a lot going on here. I believe the "lock count" panic is a red herring, and is the result of the go runtime raising a panic while handling another panic (see "panic during panic" in the log).

This issue appears to be highly related to what we see here https://github.com/golang/go/issues/24059 A fix was included in go 1.10.1. As far as I understand, an actual panic is masked by a bug in the panic handling code in the go runtime.

I suggest to build a new release candidate with go 1.10.1 and let @mschroeder223 and @daenney run that release candidate for a while. Hopefully we'll be able to catch the actual panic afterwards.

[SuperQ]

I'll work on building a new RC release.

[mschroeder223]

I don't know if this will help isolate the problem at all, but between the two servers that are continuously crashing, I updated one to exclude some unused collectors: node_exporter --no-collector.infiniband --no-collector.zfs --no-collector.wifi --no-collector.nfs --no-collector.nfsd

and the other server which continued to crash all weekend: node_exporter

Also one more crash log from the weekend but with no real trace history https://gist.github.com/mschroeder223/ca7243393e3c13d619e8ba0f517ca9b9

[SuperQ]

I've published v0.16.0-rc.1. This is now built with Go 1.10.1. Please give it a try and see if it fixes the crash.

[daenney]

Pushed it out today, I'll check back in 24hrs, see if any crashes have shown up. @grobie's line of thought sounds rather plausible though, so lets hope that is it.

[JBauto]

I'm still getting this error even with v0.16.0-rc.1. It runs for a while and then it crashes.

[grobie]

We really need a stack trace here to debug that further. Please check your journalctl output at that time without the -u node_exporter filter and paste the output.

[JBauto]

Without the filter, it doesn't show anything more useful I think.

I can confirm this is still happening with rc.0:

That happened 95268 times within two seconds. No more details/stacktrace :-/

[discordianfish]

Oh didn't know somebody ran into this long time ago already and filled an upstream issue: https://github.com/golang/go/issues/15438 Suggestions were to check unsafe and cgo code. I don't think we use any unsafe code on linux/amd64 so might be cgo or still an upstream issue.

[discordianfish]

There is also an issue here #228

[daenney]

I can confirm I'm still experiencing this. Node Exporter crashes about once every two days now with that error. Running in debug mode but not getting any stack traces in the journal either.

[daenney]

Actually... this seems to have gotten a bit worse for me. Before once the fatal error: runtime.unlock: lock count happened the node_exporter would crash and systemd would then restart it. However, now it just gets stuck in that mode, so unless I automate checking if the node exporter is still running and if not manually restart it I'm missing metrics.

[discordianfish]

Although we don't make much use of cgo on linux, it would make sense to rule this out. @daenney: Can you deploy a cgo disabled version of the node-exporter and see if that problem goes away? You can build it yourself by running CGO_ENABLED=0 go build in the repo or you can use my build:

node_exporter.gz

[daenney]

Alright. Built one with Go 1.10.1, with HEAD at 768be139beb1522b092a0ec6ab7b7b3047216577.

$ go get github.com/prometheus/node_exporter
$ cd ~/Development/go/src/github.com/prometheus/node_exporter
$ env CGO_ENABLED=0 go build

It's deployed now, lets see what happens. It might take some time for the bug to manifest though.

[daenney]

So far so good. It's been running for 3 days now roughly, no errors, hasn't been restarted by systemd since I deployed it and no missing data in any graphs (or complaints by Prometheus that the target is unreachable).

This seems to suggest it is indeed related to cgo somehow. What can I do to help narrow this down? Can we do some kind of a build matrix building a node_exporter with only one extension that uses cgo at a time to try and narrow this down? Or build it with cgo, disable all cgo-powered extensions, and then enable one at a time? Would it help to build it with cgo but on an older Go version (say 1.8)?

[discordianfish]

The only collector enabled on linux that use any cgo reference itself is timex, but this only reads some constants and I doubt that's the problem. But you could try running the official release and disable that collector. Though I suspect it's rather related to some stdlib stuff that uses c implementation instead of native go implementation. Beside that, yeah using an older go version and see if it still happens would help isolate this too.

[SuperQ]

@daenney Let's try Go 1.9.5 + CGO first. Go 1.9 seemed stable enough in node_exporter 0.15.x. So it should be the same with 0.16. If that still crashes, we can narrow it down to code changes in the node_exporter.

[daenney]

Alright. Rebuild one without CGO_ENABLED=0 on Go 1.9.5 at 75561cb1fc3364148b5ca65130a7b7eaead15475. I can rebuild it to the same commit as the 1.10.1 build I did if that's a concern.

[discordianfish]

@daenney Pretty sure that with CGO_ENABLED=0 it will work, the interesting question would be if it this problem is gone with 1.9.5 even with CGO enabled. Can you try this? Running make should do that if go 1.9.5 is installed in the PATH.

[daenney]

I think we're getting our signals crossed. I said "without CGO_ENABLED=0", meaning it's built with CGO as usual. Probably should've formulated that better. I just did a go build.

[daenney]

So far so good though, it's been running for ~2 days with no crashes yet.

[discordianfish]

Ah sorry, misread that. Makes sense!

[daenney]

Still not seeing any crashes. This does seem a bit worrisome though. If it really is a Go 1.10 vs Go 1.9 issue I'm not even sure where to begin to track that down. At least if it manifested on both we could've simply gone with a git bisect of the node_exporter.

[SuperQ]

Yea, this is not the first time the node_exporter has found a golang bug0. 🤢

I guess the only thing we can do now is to bisect the collectors and try and narrow it down.

From the original post, it seems like this is causing more issues for this combination

• Ubuntu 16.04 + 4.4 or 4.13
• VMs, rather than bare metal.

Can I ask what VM platform is causing the most issues? I could setup a test instance to see if I can reproduce it.

[daenney]

I got really annoyed with this bug so I decided to try and bruteforce it:

• Spun up an Ubuntu 16.04 instance
• Created the following fs layout:
  • /root/gophers/gopath195
  • /root/gophers/gopath110
  • /root/gophers/builds/195
  • /root/gophers/builds/110
• Downloaded and extracted Go 1.10.1 and Go 1.9.5 in /root/gophers/<version>
• Fetched node exporter:
  • GOPATH=/root/gophers/gopath110 /root/gophers/go110/bin/go get github.com/prometheus/node_exporter
  • GOPATH=/root/gophers/gopath195 /root/gophers/go195/bin/go get github.com/prometheus/node_exporter
• Found all the commit hashes of any commit between 0.15.2 and 0.16.0-rc.2 that touches a .go file: git log --pretty=format:%H v0.15.2..v0.16.0-rc.2 --no-merges -- '*.go' > /root/gophers/commits.txt

• Build a node exporter for every commit for both versions of Go:

  #!/usr/bin/env bash
  
  filename="/root/gophers/commits.txt"
  declare -i offset
  offset=0
  
  while read commit; do
        cd /root/gophers/gopath195/src/github.com/prometheus/node_exporter
        git checkout $commit
        echo "Building $commit with Go 1.9.5"
        GOPATH=/root/gophers/gopath195 /root/gophers/go195/bin/go get ./...
        GOPATH=/root/gophers/gopath195 /root/gophers/go195/bin/go build -o "/root/gophers/builds/195/node_exporter_195_$(printf "%02d" $offset)_$commit"
        offset+=1
        echo "Done building $commit with Go 1.9.5"
  done < $filename

• Repeat above for Go 1.10.1

• Create systemd files for all builds, write out targets for vegeta and start them:

  #!/usr/bin/env bash
  
  declare -i port
  port=9100
  
  for n in /root/gophers/builds/195/* ; do
        short=$(echo $n | cut -d '/' -f6 | cut -d '_' -f1-4)
        cat <<-EOF > /etc/systemd/system/$short.service
  [Unit]
  Description=Prometheus Node Exporter $port
  
  [Service]
  User=root
  ExecStart=$n --log.level="debug" --web.listen-address="127.0.0.1:$port"
  Restart=never
  EOF
        echo "GET http://127.0.0.1:$port/metrics" >> /root/gophers/targets.txt
        port+=1
  done
  
  systemctl daemon-reload
  
  for n in /etc/systemd/system/node_exporter_195_*; do
  systemctl start $(basename $n)
  done

• Repeat above for Go 1.10.1
• Launch vegeta against them: ./vegeta attack -targets=targets.txt -rate=68 > results.bin

And now we wait.

[daenney]

I think I have bad news... None of my Go 1.9.5 exporters have crashed, but on Go 1.10.1 they have, and it's at random commits, there's no logical progression. There's 5 out of the 68 that are dead. Weirdly not all of them have died with that same error, some of them appeared to have just choked and called it quits.

[SuperQ]

@daenney Thanks a ton for doing this research. For now I'm proposing we cut the release binaries with Go 1.9.5 (https://github.com/prometheus/node_exporter/pull/922). I also saw one instance of rc.2 locking up in production yesterday.

[daenney]

Glad to help. I think it would be prudent to build against 1.9.5 for now, yes.

This begs the question, is it a bug around CGO introduced in 1.10.x, or is there an actual bug in the node_exporter which due to bugfixes/changes related to 1.10.x somehow now manifests?

If someone finds it useful, I can upload all the artifacts somewhere so you can run your own tests (though it's not hard to build it yourself).

[SuperQ]

@daenney It looks like Go 1.10.2 is out, want to give that a try?

[daenney]

@SuperQ I would, except looking at the 1.10.2 milestone I can't see anything that could relate to this bug, except maybe golang/go#24935? However even that bug, I can't really see that triggering this error.

What do you think?

[LaurentDumont]

Hey everyone,

I was wondering why my Grafana dashboards we're empty and it seems I've hit the issue mentioned in this thread.

Anything else I can provide to help?

[SuperQ]

@LaurentDumont Please give rc.3 a try, it's built with Go 1.9.5, which should be more stable.

[LaurentDumont]

Awesome, thank you. I've redeployed with rc.3. I'll monitor over the next few days.

[SuperQ]

@daenney I've started up 3 test binaries on my laptop to see if I can narrow it down the issue.

1. 0.16.0-rc.3 + Go 1.9.5
2. master + Go 1.10.2
3. master -tags notimex + Go 1.10.2

I'm hitting them with ~3 QPS each.

[SuperQ]

Well, that didn't help.. the notimex variation crashed.

fatal error: runtime·unlock: lock count
fatal error: fatal: morestack on g0

And again, no other useful stack log.

[LaurentDumont]

Looks good on my side with 0.16.0-rc.3 - no crash for 24+ hours. I'll monitor over the next few days just to make sure.

[MorphBonehunter]

Last thursday i've updated my node-exporters from:

so 0.15.2 runs stable on go1.10.1 and 0.16.0 seems to have an problem on go1.10.2.

[SuperQ]

@MorphBonehunter, Thanks for the report. Are you running with the systemd collector enabled? It looks like the crash may have been in the dbus code.

[MorphBonehunter]

Yes, thats right. I've running the exporter with the following options: --log.level warn --collector.systemd --collector.netdev.ignored-devices="^br-.*|^docker.*|^veth.*" --collector.textfile.directory=/var/lib/prometheus-node-exporter

[grobie]

I'd be careful to not read too much into the last executed collector before the crash, given all the experiments around cgo and go versions.

IIRC you mentioned you had reported this to the go team @SuperQ, did anything come out of it?

[SuperQ]

@grobie True, we've seen the crash with default flags. I think we need to do some more bisecting of the collectors to see which one triggers the problem. I'm going to try spinning up a number of exporters with various flag differences.

There has been no progress in the upstream bug. We need a reproducible test case in order to convince them to investigate.

[daenney]

Interestingly, this is the first bug report that actually has a stack trace. So far every reported instance of this bug ended at fatal error: runtime.unlock: lock count.

Fwiw I wasn't explicitly running with the systemd collector enabled, so unless that happens by default I think that aspect is more of a coincidence than anything else.

[austin987]

I was able to get a stacktrace today (attached) when load testing with vegeta.

This is on an OpenRC system (Gentoo), so systemd is not the culprit. node_exporter.log

[daenney]

@austin987 You seem to be getting a different error though: fatal error: schedule: holding locks.
