========================== VNF Performance Management ========================== This document describes how to manage VNF Performance with CLI in Tacker. .. note:: The content of this document has been confirmed to work using Tacker 2024.1 Caracal, Kubernetes 1.26, Prometheus 2.45 and AlertManager 0.26. Prerequisites ------------- The following packages should be installed: * tacker * python-tackerclient CLI Reference for VNF Performance Management -------------------------------------------- .. note:: To call the VNF PM API with ``vnfpm`` subcommand, you need to use the option **\-\-os-tacker-api-version 2** 1.
