Introduction

This Azure Application Gateway discovery plugin for Pandora FMS is designed to automate the monitoring of Azure Application Gateway resources in an Azure subscription. The plugin dynamically discovers the available Application Gateways, collects their main metrics through Azure Monitor and generates agents and modules in Pandora FMS. 

 The plugin can work in two modes: creating one agent for each discovered Application Gateway, or sending all modules to a single agent configured by the user. It also supports resource group filtering, custom prefixes, discovered entity cache control, metric group selection and module filtering with allow and deny regular expressions. 

 The implemented metrics are based on Azure Application Gateway metrics, including performance, requests, backend health, latency, traffic, security, capacity, WebSocket, WAF and resource count metrics.
