Function documentationHost Analysis

 

The Host Analysis view provides applications for monitoring operating system activity and performance metrics on your managed hosts, accessing host file systems, and executing a limited set of safe OS commands.

Prerequisites

A special diagnostics agent has to be installed on every host (machine) to execute operating system commands or to browse directories remotely.

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.

Features

The Host Analysis content area initially displays a list of all hosts.

You can define queries and set filters to select data.

The following Host Analysis applications are available for the selected hosts:

  • Introscope: Launch the external Introscope application either in a Workstation or WebView context.

    For more information, see Introscope.

  • File System Browser: Allows Explorer-like navigation within the directory structure of the monitored system. Files can be displayed with a built-in viewer.

  • OS Command Console: Launch the SAP OS Command Console, where you can enter commands and command line parameters for the selected host.

    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.

    The following commands are currently available:

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.
