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 | ./pbin.sh
./poller.php -h HOSTNAME -r -f -d | ./pbin.sh

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

Most likely because you need to increase the php cache, if you’re in docker check the .librenms file and otherwise just change php.conf

Hi @ElemondCraw

Thank you for the reply, may I know where can I find the setting for php cache and I am not using docker. And little brief about the setting.

Thank you

It’s in your php.ini file
You have to change

memory_limit = 256M

And try increase it so it work

memory_limit = 2G for example for 2 gig

Hi @ElemondCraw

Thank you for the solution.
