The AppDynamics Server Visibility module uses the Machine Agent to provide extended hardware metrics and Service Availability Monitoring. Server Visibility includes additional windows in the Controller UI that enable you to quickly see underlying infrastructure issues impacting your application performance. This means you can rapidly troubleshoot hardware performance problems that are impacting your applications.
Before you Start
Server Visibility requires the following:
- The monitored machine must have a Server Visibility license.
- Server Visibility must be enabled on the Machine Agent. See Enable Server Visibility.
To view basic hardware metrics without Server Visibility, see Viewing Hardware Metrics.
Server Visibility is currently available for Linux, Windows, and Solaris. You must do the following before you enable Server Visibility:
- Review the Server Visibility Requirements and Supported Environments.
- Install and configure the Machine Agent on a machine with a supported OS as described in Install the Standalone Machine Agent.

Server Visibility User Interface
The Servers list provides key performance metrics for all your servers on a single window.
The Servers > Dashboard shows key performance metrics for the selected machine, including the top 10 consumers of CPU and memory.
The Servers > Volumes window displays performance metrics for disks, partitions, and volumes for the selected machine.
The Servers > Network window shows network performance metrics for network interfaces on the selected machine.
The Servers > Processes window shows a configurable set of performance metrics for processes.
The Servers > Containers window lists the monitored containers used by an application.
Using the Server Visibility UI
The Server Visibility user interface uses many of the same mechanisms that are common to the various windows of the Controller UI. The image below illustrates and briefly describes these mechanisms.
Search Results and Sorting
From Controller 4.5.13 onwards, pagination is the default behavior on the servers and containers list pages. The information is fetched on demand and additional records will be retrieved and displayed as a user scrolls. Search is only available for the name and host id columns. Sorting is only available on the hostname, container, metric % and health fields.
