Figure 50 LDEV Activity report
.
The maximum busiest and least busiest LDEVs are collected based on the maximum and minimum
threshold levels you specify for the selected category. The average of the total performance of each
LDEV is considered to see if that particular LDEV's performance is above the set threshold or below
the set threshold limit. This is considered for the selected date and time range, and category. Based
on their average values, they are grouped in the top 100 busiest or the least 100 busiest LDEVs and
displayed in the CSV file for that category. For each category, a separate .csv file is provided.
