Log monitoring question

[Bill Wang]

I need a log file to be monitored. this log has various error codes, like "OK", "FILE NOT EXIST", "HTTP ERROR", etc.
What I want is that when the latest logs contain some keywords "FILE NOT EXIST" or "HTTP ERROR", the trigger will be fired, and send me the alert email.
But what I got is that sometimes the subject of alert email was "PROBLEM" and the item value in message was "xxx[OK]:xxx", zabbix didn't send me the error log, but sometimes it worked well.

Does anyone know it?

No one knows? Or I didn't make myself clear?

When the trigger status is problem, the alert message doesn't send me the log detail with the "ERR" keyword, but the "OK".

Don't know why.
