High-Speed Operation Mode

Device Monitoring Studio introduces this special new mode of operation in version 5.22.

The High-Speed mode is automatically enabled for a session, for which only the Statistics visualizer is configured. In this mode the amount of data analyzed by the application is reduced significantly, leading to more accurate performance measurements. This mode is useful if you have a device with extremely high transfer rate (more than 16 MB/s) and want to measure its performance.

You may have experienced troubles doing it with a previous version of the Device Monitoring Studio, but this mode will let you to do it easily.

The High-Speed mode is not compatible with any other visualizers, or with a Logging feature. If you add any other visualizer to the session that is in High-Speed mode, this mode will automatically be switched off. The reverse is also true – if you delete visualizers from the session, so only Statistics view is left, the High-Speed mode will be automatically switched on.

The High-Speed mode is also not compatible with a Save to Log function. If the monitoring session ever was in High-Speed mode, you won’t be able to use this function to create a log. You still may start logging at any time by using the Start/Stop Logging command. This will switch off the High-Speed mode though.

You can prevent the application from entering into the High-Speed mode by turning on “Disable High-Speed mode” option in the General Settings Tab.

Automatic Data Policy Management

There has always been a feature in the Device Monitoring Studio, called “Data Processing”. It could be and still can be used to control the data processing policy. You can trade disk space usage for a session history length. More disk space you allow Device Monitoring Studio to use, more of older session packets are available for you.

Version 5.22 introduces an automatic data policy management for monitoring sessions. If only Logging and/or Statistics visualizer are configured for the monitoring session, it is forced to low disk space usage policy. If any other visualizer is configured for the monitoring session, it falls back to the setting, defined by the user.

Serial PPP View Visualizer

Device Monitoring Studio version 5.22 introduces new data visualizer for the Serial Monitor part of the application – Serial PPP View. It can be used to decode Point-to-Point Protocol packets, as well as a number of packets that can be encapsulated in PPP packets.

The current version of the visualizer supports the following protocols:

  1. Novell IPX
  2. OSI Network Layer Control Protocol
  3. DECnet Phase IV Control Protocol
  4. Appletalk Control Protocol
  5. Link Control Protocol
  6. Password Authentication Protocol
  7. Link Quality Report
  8. Challenge Handshake Authentication Protocol
  9. Multilink Protocol
  10. Compression Control Protocol
  11. Extensible Authentication Protocol
  12. NETBIOS Protocol
