•Sample Type — Defines the sampling method for the selected variable and comparing the value against the thresholds. The possible field values are:

–Delta — Subtracts the last sampled value from the current value. The difference in the values is compared to the threshold.

–Absolute — Compares the values directly with the thresholds at the end of the sampling interval.

•Rising Threshold — Displays the rising counter value that triggers the rising threshold alarm. The rising threshold is presented on top of the graph bars. Each monitored variable is designated a color.
