Several bug fixes

This release fixes a number of reported and internally discovered bugs and improves performance and reliability.

This release is dedicated mostly to polishing various application features. It improves a lot of existing components by fixing bugs and memory leaks. It also significantly reduces application memory requirements and works around memory exhaustion issues, particularly on 32-bit systems.

New Features

This release introduces high-precision session time measurement mode. As of 7.51, this mode is supported by USB, Serial and Network modules. When enabled (per-session), Device Monitoring Studio uses high-precision system timer for packet time-stamping. This mode is enabled by default if Device Monitoring Studio is installed on Windows 7 or later.

Starting from 7.51, various device information is automatically saved to a log file if the Data Recording module is added to a monitoring session. This includes the Serial Device Information for serial devices and all kinds of USB descriptors for USB devices (Device Descriptor, Configuration Descriptor and HID Descriptor tool windows).

When resulting log file is later selected in the Devices tool window, corresponding tool windows are updated with saved information.

Raw Data View and Structure View data visualizers now support additional packet coloring mode. Now they allow the user to choose one of three modes: no coloring, packet interlacing (coloring odd and even packets) and read/write coloring (coloring read and write packets).

In addition, built-in MODBUS protocol now automatically selects RTU or ASCII mode. This works automatically in Structure View and in filters and does not affect MODBUS View data visualizer.

Fixed Bugs

This release fixes over 200 different bugs, including crashes. A special attention has been paid to the following:

1. Monitoring session startup and shutdown-related issues, including crashes and hangs. This includes configuring and starting monitoring session, adding or removing data processing modules to running session and stopping monitoring session, as well as changing session's Capture Filter or visualizers' Display Filter for a running session.
2. Capture and display filter performance.
3. Protocol binding performance.
4. Issues with various data visualizers. Almost every data visualizer has been optimized or fixed in some way.
5. Workspace saving and loading issues.

Here is a short list of most remarkable fixed bugs:

Line View

Line View had a bug that prevented it from working. Now Line View works correctly when monitoring serial modems.

Correct emergency session termination

When resources are low, Device Monitoring Studio is now more robust in stopping affected high-data rate monitoring sessions, or session processing modules. This mostly affects 32-bit systems or systems with slow secondary storage.

Log file repairing

Device Monitoring Studio has always repaired damaged log files on startup. If log file was large, it introduced a startup delay (only splash screen was visible and application appeared to be hanging). Now a progress bar is shown to tell the user that application is alive.

Serial communication mode

A number of various bugs related to support for serial communication mode in Serial and Serial Bridge modules have been fixed. This includes saving the mode into the workspace or log file.

Operating with limited processing resources

During monitoring Device Monitoring Studio uses available disk space as configured in the Data Processing Tab (invoked by Tools » Settings menu command). We have fixed a number of bugs related to Device Monitoring Studio operation under limited settings (like 1% on a single disk and 0% on all others).

"Exporter" data processing modules: Raw Exporter, Text Exporter and Data Recording

A number of bugs have been fixed in exporter modules. CPU and memory usage have been carefully profiled and optimized.

Memory Usage Optimizations

This release also brings improvements to Device Monitoring Studio memory usage strategies. All critical paths have been carefully analyzed and profiled, resulting in memory usage savings of up to 10 times in several places. Application is now much more robust on systems with lower amount of RAM. In addition, when installed on 32-bit operating systems, application is now capable of sustaining much higher data rates during monitoring.

Reduced memory demands now also allow to start "heavier" monitoring sessions - sessions with more data processing modules, complex custom protocols and filter expressions.

Supported OSes

This release drops support for 64-bit Windows XP and Windows Server 2003. 32-bit versions of these operating systems are still supported.

Remote Source now requires at least Windows Vista and will not be installed on Windows XP or Windows Server 2003.

Future releases will drop support for Windows XP and Windows Server 2003 entirely.

UI Layout Update

This release will install new default UI layout (tool windows and toolbars). Any user-defined layout will be overwritten.

Trial period extension

Trial period has been extended to 21 days from 14 days.

Multiple crashes in Serial Terminal

Filtering worked incorrectly in Serial Data View and Request View

Configured filtering could incorrectly remove or duplicate monitored packets.

Multi-source Monitoring

Device Monitoring Studio supports joining monitored data from multiple sources of the same type into a single monitoring session. It is possible to monitor two or more serial ports, USB devices or network adapters. Device Monitoring Studio makes sure packets are correctly sorted and presented through a number of supported data visualizers. Data logging also supports multi-source sessions.

Remote Monitoring

DMS 7 supports monitoring USB and serial devices connected to remote servers. A single client may monitor several servers and a single server may be monitored by multiple clients. A separate server installation is provided. It includes a server access module, serial and usb monitoring modules, administration and management module and documentation. A server is managed using the MMC Snap-In or from Windows Scripting Host or PowerShell.

Windows 8 Support

DMS 7 officially supports Windows 8 and Windows Server 2012.

USB 3.0 Support

USB Monitor introduces support for USB 3.0 host controllers and devices.

Built-In and Custom Protocol Parsing

DMS 7 extends protocol parsing support for all monitoring modules: network, USB and serial. In addition, this version has new implementation of protocol parsing, which is more flexible and greatly improves performance.

New Data Processing Category

New processing category is introduced: data exporters. These are components that process monitored data in some way, but do not produce any visible output on the screen. Data recording module now belongs to this category. Other data exporters are Raw Data Exporter and Text Exporter. Both these exporters are capable of using built-in or custom protocol definitions to parse monitoring data before exporting.

Parallel Processing

New version of Device Monitoring Studio utilizes multiple cores for more responsive monitoring session operation. It basically allows the user to still perform real-time monitoring of 1 Gb network transfer without packet loss and slowdowns while having such "heavy" processing like Capture Filter and Display Filter configured for a monitoring session.

Device Tool Window

New tool window that displays all devices the user can monitor in a single customizable view. For each supported device, its image, type and current state are displayed. The user may start, stop and configure monitoring sessions, view device properties, restart and rename devices.

Sessions Tool Window

New tool window lists all currently running sessions and their properties. It allows you to close data visualizers, add new data processing modules, pause, resume or stop sessions. It also allows you to quickly change data processing modules configuration. For example, for data recording, the current log file size is displayed. By clicking "End Stream", the user ends the current stream and starts a new one.

Protocol-Based Data Visualizers

Structure View and Raw Data View data visualizers for USB, Serial and Network with additional filtering (Display Filter) and ability to specify root protocol.

Automatic Layout Loading

DMS 7 automatically loads separate tool window and command layout when monitoring session is started. Thus, until a session is started, a layout which simplifies device discovery and information retrieval is used. After the session is started, another layout is automatically loaded streamlining monitoring session usage. Both layouts may be customized by the user.

Global Configuration Switch

Device Monitoring Studio provides you with a global switch to quickly turn it into Serial Monitor, USB Monitor or Network Monitor. This switch may be used in combi installations to temporary hide unneeded components.

Session Configuration Window

New Session Configuration window greatly simplifies session creation and modification. There is a list of configured sources at the top of the window. Below are optional device configuration settings, buttons to add more devices and remove existing ones.

Depending on the type and number of configured sources, a list of available processing modules is populated. It is divided into two main categories: visualizers and exporters.

Double-click on the processing module to add it to the current session. Some of modules support configuration. Customized processing modules may be saved for future use.

Finally, the user specifies a capture filter, a generic (protocol-based) conditional expression used to filter out specific monitored packets.

Console View rendering bug

Console View incorrectly displays lines with several carriage return characters in them.

Corrupt log file handling

Device Monitoring Studio may crash when it encounters corrupted log file.

High-Speed operation mode

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.

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 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.
