Hi,

DB Schema 249
PHP 7.0.28-0ubuntu0.16.04.1
MySQL 5.7.21-20-log

====================================

[OK] Composer Version: 1.6.5
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct
[FAIL] We have found some files that are owned by a different user than librenms, this will stop you updating automatically and / or rrd files being updated causing graphs to fail.
[FIX] chown -R librenms:librenms /opt/librenms
Files:
/opt/librenms/logs/librenms.log
/opt/librenms/storage/framework/sessions/jDZIEqeOwi4EfaeFI4DZmVljZsNyojPwOUGZEHho
/opt/librenms/storage/framework/sessions/zGDWxnNkgZftH2lYGNhULmZ1MfwzreBXhfbSKQGg
/opt/librenms/storage/framework/sessions/wW2FqTXAS4NwNFI7Mra2bYph3QbbwN7L8WPhaY1d

I now how to repair this, but how to ignore this?
ls -la /opt/librenms/storage/framework/sessions/jDZIEqeOwi4EfaeFI4DZmVljZsNyojPwOUGZEHho
-rw-rw-r-- 1 www-data www-data 257 maj 11 12:28 /opt/librenms/storage/framework/sessions/jDZIEqeOwi4EfaeFI4DZmVljZsNyojPwOUGZEHho

This is a normal for me - files are created via apache2.
