This article discusses how to determine the space to allocate for the Orion SQL database.


All Orion Core versions


There is no fixed formula to determine how much space to allocate for the Orion SQL database. SolarWinds recommends a 30-day evaluation of your environment to observe the growth of your database and then adjust the retention settings. 

The database size depends on the number of the following:

  • Nodes, interfaces, and volumes you are polling
  • How much traffic is going through the devices, your retention setting for statistical polling
  • Syslog messages (if you receive them and how much you are receiving)
  • Trap messages (if you receive them and how much you are receiving)
  • Retention settings for syslogs/traps messages
  • NetFlow (95% Top Talker? DNS? IpAddressLookup?)
  • Wireless, UnDP, hardware health and other modules.

A rough guide if you have a full SLX with NetFlow, Syslog, Traps for seven days retention, is to allot an approximate of 10-50 GB to Orion Database.

  • Lastly, there are plenty of “Database Sizing” Posts on Thwack that customer can read to make a judgement on their Database Sizing.
