How to stop users from adding devices to a specific poller?

Our main LibreNMS server runs the system’s webUI and it is poller group 0. It polls about 300 devices. Three other pollers exist and they are poller groups 1, 2, 3.

We have several admin-level staff. Going forward we’d like to prevent them from adding new devices to poller group 0. The admins must still be able to add new devices to the other poller groups. Is it possible? If so, how can we configure our overall system to do that?

So far, I looked through LibreNMS’ online documentation, looked at the main server’s config.php, looked at the .env file, and reviewed the main server’s full config list via “lnms config:get --dump”. Maybe the answer was there and I just didn’t recognize it.

Thanks for any ideas you can offer.

When asking for help and support, please provide as much information as possible. This should include:

  • Steps to reproduce an issue.
  • The output of ./validate.php

If it’s an issue with the WebUI then please consider including a screenshot and the browser version you are using.

If you are having troubles with discovery/polling include the pastebin output of:

./discovery.php -h HOSTNAME -d | ./
./poller.php -h HOSTNAME -r -f -d | ./

If you need to post any text longer than a few lines, please use a pastebin service such as using non-expiring pastes.

Hi @coaldust
To my knowledge, this is not possible unfortunately. This would definitely require coding.
