Reporting the Total Traffic on an Hourly or Daily Basis

EMC Disk Arrays KM for PATROL not only monitors the traffic and activity of the disk array, controllers, LUNs and physical disks in MB/sec, but also in GB per hour or per day. The exact amount of data that was read or written to the disk array, LUN or physical disk 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 LUN 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.
