Smokeping service cannot start

Hi expert / all,

First of all i’m try to install smokeping in same server with librenms “all in one” (i’m using ubuntu 22). I’m already follow Smokeping - LibreNMS Docs and https://www.youtube.com/watch?v=cx8QNJKXqlc&list=PLxiGkbpIzunT_YOwUEukOB6DpF8N8MXkQ&index=21 … When i finish at step below then i try restart the smokeping service but it fail to restart. Do i miss any step?

Strip everything from /etc/smokeping/config.d/Targets and replace with:

*** Targets ***

probe = FPing

menu = Top
title = Network Latency Grapher
remark = Welcome to the SmokePing website of <b>Insert Company Name Here</b>. \
         Here you will learn all about the latency of our network.

@include /etc/smokeping/config.d/librenms-targets.conf

root@ubuntu:/etc/smokeping/config.d# systemctl restart smokeping.service
Job for smokeping.service failed because the control process exited with error code.
See “systemctl status smokeping.service” and “journalctl -xeu smokeping.service” for details.

Run the command at the bottom it tells you to, no one can help if you’ve not posted the error.
