eventtriggers[.exe] /create [/s Computer [/u Domain\User [/p Password]]] /tr TriggerName [/l [APPLICATION] [SYSTEM] [SECURITY] ["DNS Server"] [LOG] [DirectoryLogName] [*]] {[/eid ID] | [/t {ERROR | INFORMATION | WARNING | SUCCESSAUDIT | FAILUREAUDIT}] | [/so Source]} [/d Description] /tk TaskName

eventtriggers create:
This command creates a new event trigger that monitors and acts upon the occurrence of log events of given criteria.
