HTTP - script API

StackState Self-hosted v5.1.x

Sometimes it may be useful to process the retrieved topology or telemetry data using an external tool. For example, to perform analysis using a custom Python script, a cloud service or a Machine Learning framework. StackState can call out to any external service via HTTP using the functions in this script API.

To execute scripts using the HTTP script API in the StackState UI analytics environment, a user must have the permission execute-restricted-scripts. For details, see the analytics page permissions.
