Host Analysis 
The Host Analysis item in the navigation area gives access to the applications associated with in-depth system analysis and change analysis. To access the available applications, click the corresponding pushbutton in the navigation area.
Prerequisites
A special diagnostics agent has to be installed on every host (machine) to execute operating system commands or to browse directories remotely. A limited sets of commands can be executed within the Solution Manager without direct operating system access.
The applications grouped under Host Analysis are customized, therefore their availability depends on the corresponding application setup and on the access rights of your user role.
You have clicked the System Analysis push button in the navigation area of the Root Cause Analysis work center.
Features
The Host Analysis content area initially displays a panel with a list of All Hosts. Select one or more hosts from the list for analysis.
You can define queries and set filters to select data.
The following Host Analysis applications are available for the selected hosts:
Introscope: The pushbutton launches the external Introscope application either in a Workstation or WebView context.
For more information, see the SAP NetWeaver Administration Guide and Performance Metrics Monitoring with Introscope by Wily.
File System Browser: The pushbutton launches a browser, which allows Explorer-like navigation within the directory structure of the monitored system. Files can be displayed by using of a built-in viewer.
OS Command Console: The pushbutton launches the SAP NetWeaver OS Command Console panel, where you can enter a command and command line parameters for the selected host. The Send Command pushbutton executes the command in the target operating system context of the host, and displays the command response on the Result panel.
Parameters can be passed with the command for more filtered data. A history for the issued command can be maintained, and the sent commands (or the whole history of issued commands) can be downloaded as an MS Excel file.

Activities
You can start different host analysis applications and view their results. To start an application, select one or more hosts from the All Hosts list and click the application push button. If multiple hosts are selected, the resulting output for each host is displayed on its own tab. To close the application, click the index of the selected tab, and confirm the dialog box.
Introscope applications are external performance metrics monitoring tools on code level (e.g. average response time of a certain method). They provide historical performance data and correlate with operating system performance counters (e.g. file I/O, socket I/O, garbage collection runs).
File System Browser allows an Explorer-like navigation within the directory structure of the connected host machine.
OS Command Console is used to send certain operating system commands to connected hosts, and to view the command output without the need to access the host system physically.
