Hi all, Just sharing my experience on how I resolved a problem I was having.
Installed the system today and everything just checks out:
librenms@librenms:~$ ./validate.php
| Component | Version |
|---|---|
| LibreNMS | 21.11.0-39-g61eae8fb6 |
| DB Schema | 2021_25_01_0129_isis_adjacencies_nullable (226) |
| PHP | 7.4.3 |
| Python | 3.8.10 |
| MySQL | 10.3.31-MariaDB-0ubuntu0.20.04.1 |
| RRDTool | 1.7.2 |
| SNMP | 5.8 |
====================================
[OK] Composer Version: 2.1.12
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct
Was able to normally login and discover devices with some errors.
It was when I got into the alerting that creating, modifying or deleting was not working.
Symptoms where:
- Unable to create a new alert: Nothing would happen when clicking on save
- When trying to delete an alert I was getting an “AJAX report” error message
- When selecting “Import from” dropdown menu option within the alert definition screen I was getting an http site not found error, same as when trying to edit device settings
It wasn’t till having the last symptom described above that I realized to check the config.php file located on /opt/librenms directory. Noticed that I initially modified it during installation, used a fully qualified DNS name without having the correct DNS server in place (on local system, not in the libre system). Simply modifying the “server_name” parameter to be the server IP ADDRESS instead did the trick and now everything just works like a charm!
Hope it helps!
Regards!
