I recently updated to the newest code release today and my alertmanager stopped working with the following errors:
production.ERROR: Call to undefined function LibreNMS\Alert\Transport\logfile() {“userId”:1,“exception”:"[object] (Error(code: 0): Call to undefined function LibreNMS\Alert\Transport\logfile() at /opt/librenms/LibreNMS/Alert/Transport/Alertmanager.php:130)"}
I have turned placed selinux in permissive mode and turned off the firewall to be sure it was neither one of those causing the issues and still receiving the errors.
Any help is greatly appreciated.
