NetFlow Analyzer Disk Space Requirement
Aggregated Data:
1. Historic Data (Forever)
Connversation Data = (507000 byte * number of top record * number of interface * 2 )
Src and Dst data = 2* 58200 byte * number of interface
Application Data = 2* number of application *number of interface * 100940 byte
Historic Data = Connversation Data + Src and Dst data + Application Data
2. Top Stats Data
TopStatApplication = (507000 byte * number of top record * number of Routers )
TopStatQos = (507000 byte * number of top record * number of Routers )
TopStatConversation = (507000 byte * number of top record * number of Routers )
TopStatsData = TopStatApplication+ TopStatQos + TopStatConversation
3. One min file size :
One Min File Size = 60 bytes * 60 Min * 24 hours .
= 86400 Bytes for a interface / day.
= 86 KiloBytes for a interface / day.
Aggregated Data Space = Historic Data + Top Stats Data + One Min File
----------------------------------------------------------------------------
Raw Data:
Each flow is around 500 bytes(roughly).
So, HDD space required (in Bytes) = 500 Bytes * time in seconds * Flows Per Second.
So, HDD space required (in Bytes) = 500 Bytes * time in seconds * Flows Per Second.
For 10’000 flows per second, with a setting of 1 hours raw, how much db size will it take?
Here, (500 Bytes * 3600 seconds * 10000 Flows Per Second) calculates the space required by the flows received for 1 Hour.------------------------------------------------------------ Disk Space Needed = Historic Data + Top Stats Data + One Min File + Raw Data + 100 GB ( Installation/Report/default data ) |
