NetFlow Raw Data Settings NetFlow Analyzer classifies data into 2 types namely Aggregated Data and the Raw Data.
NetFlow Analyzer indicates the flows received per second in the Raw Data Settings tab on the Settings link. You should set the raw data period ( Retain Raw Data ) based on the calculation below: You can use the recommendation provided by the software to set your Raw data storage period. The maximum raw data storage period is 1 month and the minimum is a day. Similar to the alerting feature, you can choose to have a mail sent whenever the disk space is less than a threshold value( This is set as a percentage value). In addition you can specify the free disk space threshold below which old raw data will be cleared up. This could be as percentage value of the total disk space. This can also take on the value of "Never", in which case the disk place is not cleared up at all. One minute Data-Storage Settings To set the period for which one minute flow data has to be stored use the Retain One Minute Data option. You could choose one of 1 month, 3 months, 6 months or 1 year. You will require a free disk space of 3MB to store one month of one minute traffic data for a single interface. The default period is one day. NBAR Data-Storage Settings You can use this option to specify the time period for which NBAR data has to be retained. You could retain the NBAR data a minimum of 1 day or a maximum of 1 year. You will require a free disk space of 30 MB in order to store NBAR data for a month for each interface. The default value is 2 months.
