Reporting the Total Traffic on an Hourly or Daily Basis

IBM XiV KM for PATROL not only monitors the traffic and activity of the storage systems, storage pools and volumes in MB/sec, but also in GB per hour or per day. The exact amount of data that was read or written to the storage system, storage pool or volume 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 volume and how this evolves (with upgrades for example). In general, this will help administrators analyze the impact of various features of the storage system on the long term.
