 ## Install Azure Monitor managed service for Prometheus
 Azure Monitor managed service for Prometheus is a component of Azure Monitor Metrics. This managed service provides flexibility in the types of metric data that you can collect and analyze with Azure Monitor. Prometheus metrics share some features with platform and custom metrics. Prometheus metrics also use some different features to better support open source tools such as PromQL and Grafana.
 
-Azure Monitor managed service for Prometheus allows you to collect and analyze metrics at scale using a Prometheus-compatible monitoring solution.  This fully managed service is based on the Prometheus project from the Cloud Native Computing Foundation (CNCF). The service allows you to use the Prometheus query language (PromQL) to analyze and alert on the performance of monitored infrastructure and workloads, without having to operate the underlying infrastructure.
