LibreNMS bulk delete

There is a php script in /opt/librenms/ that lets you delete a host from the command line.

sudo /opt/librenms/delhost.php 192.168.1.20

Replace 192.168.1.20 with the hostname/ip address of the host you want to delete.

Delete Multiple Hosts

First you’ll need to get a list of devices you want to remove.  You can do this by viewing the devices in the LibreNMS MySQL database;

Example:

$ mysql -u librenms -p librenms
MariaDB [librenms]> select hostname from devices;
+----------------------------------------+
| hostname |
+----------------------------------------+
| 192.168.88.1 |
| 192.168.1.20 |
| 192.168.1.12 |
| 192.168.88.5 |
4 rows in set (0.00 sec)
MariaDB [librenms]> exit

Put all the IP addresses you want to remove into a file and run the following for loop.  Replace “remove_ip.lst” with the name of your ip list file.

for i in `cat ~/remove_ip.lst`; do sudo /opt/librenms/delhost.php $i; done
