Applications Manager's [Nginx monitoring](https://www.manageengine.com/products/applications_manager/nginx-monitoring.html) tool ensures high performance and maximum uptime. To create an NGINX Monitor, follow the steps given below:

1. Click on **New Monitor** link. Choose **Nginx Server**.
2. Enter **Display Name** of the server.
3. Enter the **IP Address or hostname** of the host in which the monitor is running.
4. Provide the **port** number in which the monitor is running.
5. Choose **SSL** option, if SSL is enabled in the NGINX Server.
6. Enter the NGINX **User Name and Password** if the NGINX Server is **authenticated**.
7. Modify the **Nginx Server Status URI** if required. This is for getting the server status. The default Server Status URI is *nginx_status*. You can modify the server status URI using this option, if the server status URI is different.
8. Enter the [polling interval](https://www.manageengine.com/products/applications_manager/help/glossary-applications-manager.html#polling-interval) time in minutes.
9. If you are adding a new monitor from the Central Server, [select a Probe Server](https://www.manageengine.com/products/applications_manager/help/enterprise-managed-server.html).
10. Choose the Monitor Group from the combo box with which you want to associate NGINX Monitor (optional). You can choose multiple groups to associate your monitor.
11. Click **Add Monitor(s)**. This discovers the NGINX Server from the network and starts monitoring them.

- **Security/Firewall Requirements:** The NGINX Server host and port should be accessible from the Applications Manager installed machine.
- **User Privilege:** The required user credentials are to be provided.

## Monitored Parameters

- **Availability** tab gives the availability history for the past 24 hours or 30 days.
- **Performance** tab gives the Health Status and events for the past 24 hours or 30 days.
- **List view** enables you to perform [bulk admin configurations](https://www.manageengine.com/products/applications_manager/help/bulk-config.html).
