In your example it will match any occurances of Xalgoz that occur anywhere in the filter string. Make sure that this is what you want. If you want to limit it to just those occurrances in the Name field you might want to use:
Code:
[Alert]
Name:[^:]*Xalgoz[^:]*:
Basically this reads as match the literal string "Name:", followed by 0 or more non-colons, followed by the literal string Xalgoz, followed by 0 or more non-colons, followed by a colon.
Look carefully at the information in the latest filters.conf.dist file. You also may want to lookup information on POSIX style regex, if the appropriate info files are installed you can find it by using the command:
and navigating around the information contained therein.
