If you run these commands manually, what does it say?

dlesel · 3 December 2025 13:17

[librenms@libremon ~]$ php ‘artisan’ maintenance:cleanup-syslog
Could not open input file: ‘artisan’

murrant · 5 December 2025 07:00

You need to be in the directory where LibreNMS is installed. Of you are and that file doesn’t exist, your install is broken. Validate it.

dlesel · 5 December 2025 14:01

I am in the directory where LibreNMS is installed.
The artisan file is located in this directory.
I believe the problem is related to the command syntax.

[librenms@toc-libremontst ~]$ php artisan maintenance:cleanup-syslog
Cleared syslog entries older than 30 days (547696 rows)

[librenms@toc-libremontst ~]$ php ‘artisan’ maintenance:cleanup-syslog
Could not open input file: ‘artisan’

[librenms@toc-libremontst ~]$ php ‘artisan’ maintenance:cleanup-syslog
Cleared syslog entries older than 30 days (0 rows)

[librenms@toc-libremontst logs]$ /usr/bin/php ‘artisan’ maintenance:cleanup-syslog
Could not open input file: artisan
[librenms@toc-libremontst logs]$ php ‘artisan’ maintenance:cleanup-syslog
Could not open input file: artisan

murrant · 8 December 2025 19:36

This looks like a wrong quotes problem

Could not open input file: ‘artisan’

if you want to use quotes in the cli, you need to use ' or ", not ‘ and ’

elherr · 9 December 2025 00:28

I have the same errors in my librenms.log. php artisan commands complete normally (see below). Currently doing cleanups via cron job as a workaround.

maintenance:cleanup-syslog is does not emit exit code 2…

I wonder if it is a timeout or something. Or maybe an SQL error? To bad the error message doesn’t have anything more helpful.

dlesel · 22 December 2025 14:15

As Tony mentioned above, you need to be in the directory where LibreNMS is installed.
Try running this command from cron:

php /opt/librenms/artisan maintenance:cleanup-syslog

I believe all /laravel/framework/ exceptions occurred because the path to the artisan file was missing.

For example:

[librenms@toc-libremontst Scheduling]$ pwd
/opt/librenms/vendor/laravel/framework/src/Illuminate/Console/Scheduling

[librenms@toc-libremontst Scheduling]$ php artisan maintenance:cleanup-syslog
Could not open input file: artisan

[librenms@toc-libremontst Scheduling]$ php /opt/librenms/artisan maintenance:cleanup-syslog
Cleared syslog entries older than 30 days (2229 rows)

Using the full path to artisan should resolve the issue.

My workaround in /etc/cron.d/librenms

Added symbolic link to /opt/librenms/artisan in ~/vendor/laravel/framework/src/Illuminate/Console/Scheduling.

I’ll check to see if borkage occurs tonight. I know next to zilch about PHP and Laravel to troubleshoot much beyond that.

librenms@libre:~/vendor/laravel/framework/src/Illuminate/Console/Scheduling$ ln -s /opt/librenms/artisan artisan
librenms@libre:~/vendor/laravel/framework/src/Illuminate/Console/Scheduling$ php artisan maintenance:cleanup-syslog

My LibreNMS instance is from 2021, for whatever reason it stopped getting software updates in April 2025, after I finally got it updated back to latest I started getting this exact same error.

After a week of failing to fix it I created a completely fresh Ubuntu 24.04.3 LTS install and followed the install guide here to the letter Installing LibreNMS - LibreNMS Docs and it does exactly the same thing.

maintenance.log is never written to and librenms.log shows this;

Is this related to my finding here? MySQL-db "exploded" in size - #2 by ChrisK928

elherr · 5 January 2026 19:52

Yes, IMO. grep your logs/librenms.log for ‘cleanup-syslog’ and you should see the borkage. I put in a cron job to clean up syslog until it gets fixed.
