Librenms Tidbits

To identify and see what’s wrong with the NMS, run and check the problem by issuing-

./validate.php

If RRD files not being updated in rrd folder, check-

./poller.php -h HOSTNAME -d -f -m os

Reset LibreNMS by dropping database-

DROP DATABASE `librenms`;
CREATE DATABASE `librenms`;

php build-base.php

Admin password reset (or create new admin user in case you’ve forgotten the existing user)-

./adduser.php <USERNAME> <PASSWORD> 10

If receiving such error while installing Librenms, run-

./scripts/composer_wrapper.php install --no-dev

If you’re having poller issue (assuming cron fails), run-

/opt/librenms/poller-wrapper.py
