I notice my Systemd graph has error on all device monitored. And found that when I manually run
./lnms device:poll all
The poller will always error at systemd.inc.php line 28:
Application: systemd, app_id=81Cannot redeclare data_update_helper() (previously declared in /opt/librenms/includes/polling/applications/systemd.inc.php:28) {"exception":"[object] (Symfony\\Component\\ErrorHandler\\Error\\FatalError(code: 0): Cannot redeclare data_update_helper() (previously declared in /opt/librenms/includes/polling/applications/systemd.inc.php:28) at /opt/librenms/includes/polling/applications/systemd.inc.php:28)"}
In systemd.inc.php line 28:
Cannot redeclare data_update_helper() (previously declared in /opt/librenms/includes/polling/applications/systemd.inc.php:
28)
However, if I poll only to each individual host, the poll finishes but still no graph.
./poller.php -h 13
This is my validate.php result
librenms@librenms:~$ ./validate.php
