Applications not work

I migrated the librenms to a new server, and after that, all my monitored applications no longer receive any information, remember that our monitored servers were not altered.

I monitor Proxmox, Asterisk, HTTP, and none of them receive any more information.
If I run ./discovery.php -h DEVICE -d -m Applications,
I get this:

Execution time for ‘applications’ from the discovery module: 0.0240 seconds with 259192 bytes
SNMP: [1/0.02s] MySQL: [3/0.03s] RRD: [0/0.00s] #### Unload applications from the disk module ####

Does anyone know how to fix this?

What device type and OS is this device?

If you go to the devices’ Settings, then the Modules tab and under Discovery Modules look for Applications is it enabled?

It could be that if this is an appliance of some sort that doesn’t show up as a standard Linux OS server, you might not get app discovery enabled at the OS level. Maybe your global app discovery settings was enabled on your old server but it disabled on the new one (which I believe is the default)?
