To start viewing statistics for a BIG-IP® device, you must enable statistics collection for that device. You can do that either during or after adding the device to the BIG-IP Devices inventory list on the BIG-IQ® system.

|When does data from one container pass on to the next?||Data passes from one container to the next in increments that are the size of the next (larger) container. That is, every 60 minutes, the last 60 minutes of raw data is aggregated into a data set and passed to the Hour(s) container. Every 24 hours, the last 24 hours of hourly data is aggregated into a data set and passed to the Day(s) container, and so on for the Month(s) container.|

percentage of total disk space that you want data to consume on the
data collection devices in your cluster.
If more disk space is consumed than the percentage you specified, BIG-IQ takes two actions:
