## Problem/Question On a fresh Ubuntu 22.04 LTS install the applications, users, etc graphs are missing. I have another Ubuntu 22.04 system using the same version including kernel and this does not have this issue. ## Relevant docs you followed/actions you took to solve the issue I noticed the service has an error message for ebpf plugin which the other system does not have. ```auto # service netdata status ● netdata.service - Real time performance monitoring Loaded: loaded (/lib/systemd/system/netdata.service; enabled; vendor preset: enabled) Active: active (running) since Tue 2022-06-14 05:16:14 EDT; 16min ago Main PID: 11824 (netdata) Tasks: 82 (limit: 154433) Memory: 90.6M CPU: 16.015s CGroup: /system.slice/netdata.service ├─11824 /usr/sbin/netdata -D -P /var/run/netdata/netdata.pid ├─11826 /usr/sbin/netdata --special-spawn-server ├─11969 bash /usr/libexec/netdata/plugins.d/tc-qos-helper.sh 1 ├─11984 /usr/bin/python3 /usr/libexec/netdata/plugins.d/python.d.plugin 1 ├─11988 /usr/libexec/netdata/plugins.d/freeipmi.plugin 1 ├─11990 /usr/libexec/netdata/plugins.d/go.d.plugin 1 └─11992 /usr/libexec/netdata/plugins.d/nfacct.plugin 1 Jun 14 05:16:14 ubuntu systemd[1]: Started Real time performance monitoring.

I was able to fix the issue partly by fixing the file permissions up. chmod 4755 /usr/libexec/netdata/plugins.d/apps.plugin -rwsr-xr-x 1 root netdata 585616 Jun 13 20:28 apps.plugin The problem is that now i am noticing lots of the below errors in the logs. ```auto 022-06-14 12:39:28: apps.plugin ERROR : MAIN : Cannot process /proc/1/io (command 'systemd') (errno 13, Permission denied) 2022-06-14 12:39:28: apps.plugin ERROR : MAIN : Cannot process /proc/2/io (command 'kthreadd') (errno 13, Permission denied) 2022-06-14 12:39:28: apps.plugin ERROR : MAIN : Cannot process /proc/3/io (command 'rcu_gp') (errno 13, Permission denied) 2022-06-14 12:39:28: apps.plugin ERROR : MAIN : Cannot process /proc/4/io (command 'rcu_par_gp') (errno 13, Permission denied) ``` ---

Hello @steve5518 and welcome in our community. You shouldn’t have to change permissions by yourself. Let me forward your ticket (internally) ---

Hello @steve5518, Welcome to our community. Firstly let me do a question to try to replicate the issues, because my VM running Ubuntu 22.04 does not have these issues when I compile netdata from scratch. How did you install your netdata? About the error “Your environment does not have BTF file /sys/kernel/btf//vmlinux. The plugin will work with ‘legacy’ code.” , this means that on Ubuntu they did not compile the current kernel ( 5.15.0-33-generic #34-Ubuntu) with support to `BTF` files, so instead to use trampolines, `ebpf.plugin` is forced to use kprobe. Considering everything you wrote until now, it looks like that at the end of the installation, the plugins were not set with correct permissions. Both `apps`and `ebpf` needs this special permission, because they are touching files that were made by user `root`. Best regards!
