i guess i have to give up and we can use this issue for discussions
andres, i have a list of issues that annoy me heavily when using zabbix. HEAVILY. this one is not on that list, yet... so priorities for different users differ a lot
would i want this feature ? sure. it's a nice one. but look at the long lost of open issues and you will see that there are thousands of them.
while it may sound simple, almost all issues have initially unforeseen problems once we start to figure out what such a change would require. let me provide two examples...
a) changing default history period from 90 to 7 days. sounds extremely simple, right ? just change one number... well, first it would require major release, because it is also in the database schema. second, that value also affects for how long web scenarios keep historical data, and it can not be configured by user. so we would have to implement that functionality. see how one number change drags in extra feature ?
b) currently lowest 2 severities are ignored for it services. should be simple to fix, right ? just make them not ignored... turns out, trigger severity is stored as ok/problem state for it services. trigger severities start at 0, but in it services 0 means ok. to make this change we must change the way data is stored, provide database patch for users that upgrade... so this simple change again turns out to pull in unforeseen changes.
as for this specific one, see the link marc posted - this specific feature is now at the top of the list (thanks, sergey)
