Investigating a suddent drop in Required server performance vps,
I found out that the update interval of trapper items is included in the calculation.

however, you cannot modify or see the update interval for this kind of items...

I understand the vps is just a rough estimation, but by mass updating a single template applied to just 3 hosts out of 200 , I changed the from 15 to 144vps,
making the "rough" part an understatement...
