Query

Universal query that matches all time series unconditionally. This operator returns a query expression that evaluates to true for any input, effectively selecting all available time series data. It's useful as a starting point for complex filtering or when you need to include all data.

Parameters

  • None - this operator takes no parameters

Examples

Select all time series (typically used as a base for further filtering):

:true

Combine with logical operations to create complex queries:

:true,name,cpu,:eq,:and    # Equivalent to just name,cpu,:eq
  • :false - Universal query that matches no time series
  • :and - Logical AND (:true with any query returns that query)
  • :or - Logical OR (:true with any query returns :true)
  • :not - Logical NOT (:true,:not is equivalent to :false)
