Orion SWQL or Solarwinds Query Language is a pseudo SQL type statements. If you know the basic structure of SQL, Select from join where order group by, you will easily pickup SWQL queries.

PURPOSE: This is an overly simplified guide for Keep the lights on SQL to Expert SQL users wanting to jump into Solarwinds Query Language as fast as possible.

Where is SWQL used?

• Every Web Resource on the Web Console
  
• Alerts
• Reports
• SDK/API scripting

Why should I use SWQL?

    Solarwinds has designed SWQL to be future proofed for users and development.

Note: A lot of this information exists in multiple places, I am just combining the different points to help provide a better picture to start creating queries easily.

• SWIS Examples.
  • Understand all of the different SWQL Functions. If you want to do more than just join a table, this included converting time, check values, and the more basic SQL type commands min,max, average.
• SWIS Table Reference.
  • Want to know where to find the Node Data or the Applications, Storage or Virtual etc would be within SWQL? This covers the main key reference tables, the identifier id, and how to reference it up the chain from Component to Application to Node to Engine.
  • Some of this information came from Orion.NetObjectTypes. SWIS Parent and Column Details were added to see the relationship to the next table.
  • This section will be continuously updated. The main Core modules are currently mapped, and others are still being finalized.
