Standard library

Grafana Agent Flow is still growing, and its standard library isn’t mature yet. If you have a request for extensions to the standard library, please leave feedback on our dedicated GitHub discussion for River feedback.

The standard library is a list of functions which can be used in expressions when assigning values to attributes.

All standard library functions are idempotent: they will always return the same output if given the same input.
