Aggregate item problem (grpmax)

[sorlov]

Hi everybody!
Need Help.
We have aggregate item with strange problems.
Item key:
grpmax["API servers","tt.api.slow_searches_ratio",last,0]

Sometimes we see freeze data-area on graph. Like on this screen.



All items with witch collect to this aggregate item is ok, and have no data freezing.

Solved

Solved by fixing calculated item.
We have scheme like that:
Trapper item --> calculated item --> aggregate item

When calculated item don`t have data it freeze at the last value.
Fix it by change function.
