in reply to function calling

For a subroutine call, Parentheses are optional if predeclared/imported.

So, in the second case it is optional and in the first case it is not optional.

[Corion]: marto: Ow! I would assume there is a cron job monitoring the free disk space and automatically opening a ticket at 90%, 95% and 100% usage...
[Corion]: Even we had automatic emails back when we maintained the machine ourselves...
[marto]: Corion you under estimate how lazy these admins are :P
[Discipulus]: we too; using opsview alarms
[marto]: the key word: outsourcing ;)
[Corion]: marto: Yeah, feels like that ;) You could set up the cronjob that auto-creates tickets :-))
[marto]: the ticketing system does not accept calls via email, nor has it a working API. It's tied into Active Directory for authentication and the Solaris boxes aren't on that domain
[Corion]: The one thing I haven't figured out a solution to is how to get an edge-trigger instead of sending an email every 5 minutes if the usage is above 90%. I want one mail when it goes over 90% but no more emails as long as it stays between 90% and 95%.
[Corion]: marto: Clever! ;)
[Corion]: You can only reach me by pager
