Hi there, I'm trying to create a new metric beat and to do this I followed the official guide for dev [Creating a Metricset | Beats Developer Guide [7.16] | Elastic](https://www.elastic.co/guide/en/beats/devguide/7.x/creating-metricsets.html) I cloneed the beat repository with git and moved out in the directory metricbeat and typed in the terminal make create-metricset as suggested in the guide but I obtain an error and I don't know why: > Blockquote > make create-metricset > mage createMetricset > make: mage: Command not found > make: \*\*\* [Makefile:8: create-metricset] Errore 127 ---

I think you need to install the mage build tool: [https://github.com/magefile/mage](https://github.com/magefile/mage) ---
