Query

Universal query that matches no time series unconditionally. This operator returns a query expression that evaluates to false for any input, effectively excluding all time series data. It's useful for creating empty result sets or as a component in logical expressions.

Parameters

  • None - this operator takes no parameters

Examples

Create an empty query (matches nothing):

:false

Use in logical operations:

:false,name,cpu,:eq,:or    # Equivalent to just name,cpu,:eq
name,cpu,:eq,:false,:and   # Always produces empty results
  • :true - Universal query that matches all time series
  • :and - Logical AND (:false with any query returns :false)
  • :or - Logical OR (:false with any query returns that query)
  • :not - Logical NOT (:false,:not is equivalent to :true)
