1 Day 5 Minutes Real-time statistics are rolled up to create one data point every 5 minutes. The
result is 12 data points every hour and 288 data points every day. After 30
minutes, the six data points collected are aggregated and rolled up as a data point
for the 1-Week time range.
You can change the interval duration and archive length of the 1-Day collection
interval by configuring the statistics settings.
1 Week 30 Minutes 1-Day statistics are rolled up to create one data point every 30 minutes. The result
is 48 data points every day and 336 data points every week. Every 2 hours, the 12
data points collected are aggregated and rolled up as a data point for the 1-Month
time range.
You cannot change the default settings of the 1-Week collection interval.
1 Month 2 Hours 1-Week statistics are rolled up to create one data point every 2 hours. The result
is 12 data points every day and 360 data points every month (assuming a 30-day
month). After 24 hours, the 12 data points collected are aggregated and rolled up
as a data point for the 1-Year time range.
You cannot change the default settings of the 1-Month collection interval.
1 Year 1 Day 1-Month statistics are rolled up to create one data point every day. The result is
365 data points each year.
You can change the archive length of the 1-Year collection interval by configuring
the statistics settings.
Note If you change the duration of data collection intervals you might need to allocate more storage
resources.
Data Collection Levels
Each collection interval has a default collection level that determines the amount of data gathered and
which counters are available for display in the charts. Collection levels are also referred to as statistics
levels.
