I would add that even with this configuration in Netdata does not show the metrics described at https://learn.netdata.cloud/docs/collecting-metrics/ebpf/ebpf-socket (I am interested in I have made sure that |

Hello @nodiscc , Thank you for your feedback. We are now working with sockets again, and we are going to consider everything you wrote to improve. Best regards! |
|
@thiagoftsm, excuse me, what exactly are you going to consider? @nodiscc is saying that he followed https://learn.netdata.cloud/docs/collecting-metrics/ebpf/ebpf-socket and get He did some testing and found out that
So what are you going to consider? Is he wrong or our documentation is wrong/a bug in ebpf plugin? |
Expected because it is a different file. The ebpf plugin has modules and their configurations are in the ebpf.d directory. |
Hi @ilyam8 sure, I understand that this message may be part of normal operation. The problem is that the charts are not shown when I create Can you reproduce the problem on your side? As I said, just need to follow https://learn.netdata.cloud/docs/collecting-metrics/ebpf/ebpf-socket |

@thiagoftsm could you help confirm if current documentation on https://learn.netdata.cloud/docs/collecting-metrics/ebpf/ebpf-socket is correct? are we missing something for user to be able to enable this specific module? |
Bug description
https://learn.netdata.cloud/docs/data-collection/ebpf/ebpf-socket indicates that one must run
sudo ./edit-config ebpf.d/network.confto create the ebpf plugin configuration. This creates/etc/netdata/ebpf.d/network.conf.However after restarting netdata, no ebpf.plugin charts are shown. Netdata logs the following message:
sudo mv /etc/netdata/ebpf.d/network.conf /etc/netdata/ebpf.d.confand restarting netdata fixes the problem.I believe either the documentation is wrong, or the configuration is not being loaded from
/etc/netdata/ebpf.d/network.confwhen it should.Expected behavior
Following https://learn.netdata.cloud/docs/data-collection/ebpf/ebpf-socket should yield a working ebpf.plugin configuration/display ebpf charts.
Steps to reproduce
/etc/netdata/ebpf.d/network.confaccording to the documentation...
