NetApp Filers KM for PATROL not only monitors the traffic and activity of the filer in MB/s, but also in GB per hour or per day. The exact amount of data that was read, written, received and transmitted to the filer is calculated for each hour of the day and each day of the week.
The hourly report graph will represent the amount of data in GB from 12:00am to 12:59am, from 1:00am to 1:59am, from 2:00am to 2:59am, etc, while the daily report graph will represent the amount of data in GB for Monday, for Tuesday, for Wednesday, etc.
This report is notably helpful to SAN administrators to understand the impact of the nightly backups, of the amount of data a specific application writes to a filer and how this evolves (with upgrades for example). In general, this will help administrators analyze the impact of various features of the disk array on the long term.
