 NGINX Agent is a companion daemon for your NGINX Open Source or NGINX Plus instance. It enables:
 - Remote management of NGINX configurations
 - Collection and reporting of real-time NGINX performance and operating system metrics
 - Notifications of NGINX events

 # How it Works
-Agent runs as a companion process on a system running NGINX. It provides gRPC and REST interfaces for configuration management and metrics collection from the NGINX process and operating system. Agent enables remote interaction with NGINX using common Linux tools and unlocks the ability to build sophisticated monitoring and control systems that can manage large collections of NGINX instances.

 ## Configuration Management
-Agent provides an API interface for submission of updated configuration files. Upon receipt of a new file, it checks the output of `nginx -V` to determine the location of existing configurations. It then validates the new configuration with `nginx -t` before applying it via a NOHUP signal to the NGINX master process.

It then validates the new configuration with `nginx -t` before applying it via a NOHUP signal to the NGINX master process.
 
 ## Collecting Metrics
-Agent interfaces with NGINX process information and parses NGINX logs to calculate and report metrics. When interfacing with NGINX Plus, Agent pulls relevant information from the NGINX Plus API. Reported metrics may be aggregated by [Prometheus](https://prometheus.io/) and visualized with tools like [Grafana](https://grafana.com/).

 ### NGINX Open Source
-When running alongside an open source instance of NGINX, Agent requires that NGINX Access and Error logs are turned on and contain all default variables.
+When running alongside an open source instance of NGINX, NGINX Agent requires that NGINX Access and Error logs are turned on and contain all default variables.
 
 ### NGINX Plus
-For Agent to work properly with an NGINX Plus instance, the API needs to be configured in that instance's nginx.conf. See [Instance Metrics Overview](https://docs.nginx.com/nginx-management-suite/nim/about/overview-metrics/) for more details. Once NGINX Plus is configured with the `/api/` endpoint, Agent will automatically use it on startup.

 ## Event Notifications
-Agent allows a gRPC connected control system to register a listener for a specific event. The control mechanism is then invoked when Agent sends an associated system signal. The source of a notification can be either the NGINX instance or Agent itself. Here's a list of currently supported events:

 # Installation
 ## Installing NGINX
-Agent interfaces directly with an NGINX server process installed on the same system. If you don't have it already, follow these steps to install [NGINX Open Source](https://docs.nginx.com/nginx/admin-guide/installing-nginx/installing-nginx-open-source/) or [NGINX Plus](https://docs.nginx.com/nginx/admin-guide/installing-nginx/installing-nginx-plus/). Once installed, ensure the NGINX instance is running.

 ## Logging 
-Agent uses formatted log files to collect metrics. Expanding log formats and instance counts will also increase the size of Agent log files. We recommend adding a separate partition for `/var/log/nginx-agent`. Without log rotation or storage on a separate partition, log files could use up all the free drive space and cause your system to become unresponsive to certain services.
