eBPF not working

Hey All,

I’ve got netdata running on some test machines, but I can’t get the eBPF data reporting. I have it enabled in netdata.conf and in ebpf.d.conf with disk = yes.

But I’m not seeing any data locally or via netdata cloud, no eBPF on the bottom right hand side or disk latency stats are being reported.

Where can I start to troubleshoot this?

Edit: Running * v1.31.0-279-nightly, latest Ubuntu 18.04 inside a VMware VM.

Hello @tjk welcome!

what do you see if you run

grep 'ebpf' /var/log/netdata/error.log

maybe try it just a few mins after a netdata restart too perhaps.

That might show some info and maybe our eBPF expert @Thiago_Marques_0 might be able to help.

root@/var/lib/netdata# systemctl restart netdata

root@/var/lib/netdata# grep 'ebpf' /var/log/netdata/error.log

Hello @tjk ,

I remember that Ubuntu 18.04 had some problems when we were using kernel 4.18.x, and it was disabled it in the past, please, run the following commands and verify whether it will run on Ubuntu:

cd /etc/netdata/
./edit-config ebpf.d/ebpf_kernel_reject_list.txt

When your favorite editor opens, please, remove the line inside the configuration file.
After this, try restart Netdata.

Any doubt, please let us know.

Best regards,

Thiago

Thanks, this didn’t work.

In that file was Ubuntu 4.18.0, I removed it and restarted netdata.

Not sure if it helps, but this was working 3 or 4 weeks ago on the same VM. I went back to look at latency stats earlier today and noticed they were not working any longer.

Not sure if an update in the agent over the last couple of weeks broke it or what happened, but it was working.

This was the guide I followed: eBPF monitoring with Netdata | Learn Netdata

And this scripts return null value, saying it is compatible: curl -sSL https://raw.githubusercontent.com/netdata/kernel-collector/master/tools/check-kernel-config.sh | sudo bash

Hello @ilyam8 and @tjk ,

I tested now on a VM that I have Ubuntu 18.04, this VM has 3 kernels 5.4, 4.18, and 4.15 . I compiled the latest Netdata code with few modifications that have relationship with PRs I am working. When I compiled, I was running kernel 5.4 and I did not have problems to run eBPF plugin on all these kernels.

@tjk considering what @ilyam8 wrote for us, I have questions for you:

  • do you have the directory /usr/libexec/netdata/plugins.d/ ebpf.d?
  • Please, can you stop netdata and go to directory /usr/libexec/netdata/plugins.d/and after this to run ./ebpf.plugin?
  • Finally, I saw that you are running nightly Netdata. Are you also updating Ubuntu every day? I was 10 days without turn on this VM , and I had to wait more than 1 hour before to recompile the whole Netdata.
  • Did you have problems between Netdata update?

Best regards!

Yes, I have this directory, in it are a bunch of pnet* and rnet* files.

Here is the output of ./ebpf.plugin:

I am not updating Ubuntu everyday no. I also am not manually updating netdata each day. I set netdata up 4 weeks ago on these vm’s, got disk latency working for ebpf and didn’t touch it until earlier this week. I went to look at disk latency performance and the entire ebpf menu on the right hand side was gone.

The kernel versions are:
4.15.0-154-generic
4.15.0-156-generic
4.15.0-158-generic

Anything else you would like me to try @Thiago_Marques_0 ?

OK, I enabled HWE and installed the latest 5.4.0-86-generic #97~18.04.1-Ubuntu and eBPF is working again, so something on the 4.15 kernel was working, and then one of the netdata nightly agent updates broke it.

@Thiago_Marques_0 I have the same problem. Also, when I restart netdata service, the ebpf.plugin keeps hanging until I kill it manually.
