Please help me since the same issue on the internet so far not worked for me. I created a few snapshot so I can revert if I mess the config.

It looks to me like for some reason your poller cron jobs aren’t running, which could be a number of things. That would be related to this set in the install guide:
https://docs.librenms.org/Installation/Install-LibreNMS/#cron-job

So here are some ideas…

Check that the cron file exists and the permissions look OK:
sudo ls -alh /etc/cron.d/librenms

If so, make sure the contents of the file make sense:
sudo cat /etc/cron.d/librenms

For example, if you installed LibreNMS to a non-standard path (something other than /opt/librenms/) you might have to modify the cron file.

Finally, if you installed Ubuntu Server minimal or some other custom install, you might not have the cron package installed.

Check:
sudo systemctl status cron

If installed and running you should see the service as active. If not maybe:

sudo apt update
sudo apt install cron

Hi Slashdoom!

You really really help me!
The cronjob is not install because I installed minimal ubuntu server.

Thank you, really appreciated it.
