There is no conntrack insert_failed metrics in node_exporter

[DesireWithin]

Hello,

I don't hava nf_conntrack_stat_insert_failed (and other metrics).

I have read related issue #1155 and related #1093 and prometheus/procfs code.
#1155 and the code require there is a stat file /proc/net/stat/nf_conntrack on the procfs
and 1093 require CAP_NET_ADMIN privilege which is already closed.

My Linux don't have /proc/net/stat/nf_conntrack, I checked the following kernels:

• 4.15.0-213-generic Ubuntu 18.04 LTS
• 5.4.0-125-generic Ubuntu 20.04.1 LTS
• 5.15.0-76-generic Ubuntu 22.04.2 LTS (Jammy Jellyfish)

They don't have CONFIG_NF_CONNTRACK_PROCFS in /boot/config-xx

However there is an exception, I don't know why, perhaps deviated with this issue.

Node_exporter version is 1.6.1 , command line is

in k8s:
- --web.listen-address=:9100                              
- --web.config.file=/etc/node-exporter/config/config.yaml 
- --path.rootfs=/host                                     
- --no-collector.ipvs                                     
- --collector.processes                   
in host:
 --collector.processes --collector.logind --log.level=error --collector.systemd --collector.tcpstat --collector.textfile.directory=/opt/node_exporter/metrics --web.listen-address=:9100                

So, what should I do if I don't have /proc/net/stat/nf_conntrack? Should I use a different collector(like this), or a textfile collector?
