We had an item for log[/path/to/log/server.log, ERROR] that was working fine until a configuration change broke the process and removed the zabbix access to the log file. In the Latest Data you can see it's failing to update with the message "Permission Denied". Now barring repairing the permissions, how can we go about making a trigger on if it can't actually read the file? Is it possible native to zabbix?
