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:

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.

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.
