Configuring the System Statistics probe

You can configure the System Statistics probe to run on Linux™ or Windows™.

The system statistics probe runs on a host machine that can be configured in the Architecture School Physical View.

To run the system statistics probe on Linux, you must install Libstatgrab version 0.17 library. This library is used to provide access to statistics about the system on which the probe is run. Note that later versions of Libstatgrab are available, but these are not supported by the system statistics probe. Libstatgrab can be downloaded from http://www.i-scream.org/. To build and install the library, follow the instructions provided with the download.

  1. To configure the default probe or to add another, edit the host and click the Probes tab.

  2. Next, you can choose from one of the following actions:
    • To add a new probe, click Add > System Statistics.
    • To copy an existing probe, select the probe and click Copy.
    • To delete a probe, select the probe and click Remove.
    • To configure an existing probe, select it and modify the settings in the configuration panel on the right.
  3. For probes other than the default one, you can enter a name in the Name field.

    Set the interval (in seconds) at which statistics are to be collected in the Collect statistics every ... field.

    Under Processes, select whether you want the probe to monitor all running processes on the host (Monitor all processes) or a selected subset of processes (Monitor a set of processes).

  4. If you select the subset option, you can add the name of a process to monitor by clicking Add.

    To edit the name of an existing process, select it and click Edit.

    To delete an existing process, select it and click Delete.

    Note:
    If the subset option is selected and no process names are defined, no processes are monitored (that is, the probe does not produce any data).
  5. To select or change the agent that hosts the selected probe, click Browse next to the Hosting agent field and select the agent you want from the project resource tree.

    To clear the current selection, click Clear.
