Hi,

I've been looking for existing ticket, but failed to find any.
I'm trying to create some complex trigger expression to monitor our HDD disk size on mixed environment and the simple last(0)<10% is no longer good enough. Instead we're using the following expression:

{Template_Data01:vfs.fs.size[/data01,free].last(0)}

/

{Template_Data01:vfs.fs.size[/data01,free].change(86400)}

<14

Which roughly means that the disk has enough space to write 14 times the difference in the last 14 days.
The problem is that I'd like to graph this expression in order to analyze and check if the 14 days is actually good enough and possibly show that graph over a period of time.

In general, It would be good if we could graph any kind of trigger expression as a derived item in "Latest Data" and check if we should add a new trigger based on the history/trend of that expression (ie, we could do a long term graph of .abschange(86400) and after some proper analysis, add a trigger based on that.
