# Set thresholds for monitored items in Overview elements

Thresholds activate automatic tracking of monitored items in Overviews. The values of the monitored items are checked once an hour.

##

For Progress items, the total of the values is compared to the threshold limit. The threshold is considered exceeded if the average level of the curve is above the threshold limit during the tracking period.

For Top Rate and Top Rate Curve items, the highest value is compared to the threshold limit. The threshold is considered exceeded if the highest value is above the threshold limit during the tracking period. If the threshold limit is exceeded, an alert is sent.
