Help Information

General Information
+   What is hIOmon?

Designed and developed by hyperI/O LLC, the hIOmon software provides storage performance monitoring tools that can examine and efficiently record the activity and performance of the device and file I/O operations.

These tools, such as the hIOmon "Workload I/O Profiler (WIOP)", enable you to immediately collect, display, and export automatically-summarized I/O operation performance metrics — moreover, in a simple, quick, and easy fashion.

hIOmon enables you to determine and evaluate your particular storage I/O operation performance (especially the particular "I/O profiles" pertinent to your specific applications, workloads, and devices) in an efficient, timely, and cost-effective manner.

See hIOmon Tools Overview for more information.

+   What is the hIOmon Disk I/O Ranger Display?

The hIOmon Disk I/O Ranger Display can be used to display of the hIOmon "Performance Threshold Range Metrics", which are a set of summarized I/O operation performance metrics that are specifically focused upon the ranges of I/O operations per second (IOPS), megabytes-per-second (MB/s) data transfer rates, response time (RT), I/O operation queue depths/lengths (QD), and data transfer sizes/lengths (DTS) actually observed by the hIOmon I/O Monitor for individual devices, files, and processes.

For example, the "IOPS 1 - 99" Range Count metric for read I/O operations reflects the number of one-second intervals during which the hIOmon I/O Monitor actually observed a total number of monitored read I/O operations that was one or more, but less than 100 read I/O operations.

The unique hIOmon Performance Threshold Range Metrics, which are automatically aggregated in a summarized manner by the hIOmon I/O Monitor software component, provide a simple, quick and easy way to assess the actual "speeds and feeds" I/O operation performance of your particular devices, files, and applications in everyday, normal usage.

The hIOmon Disk I/O Ranger Display application software component is included within hIOmon software packages such as the hIOmon "Workload I/O Profiler (WIOP)" and the hIOmon "Workload I/O Profiler for Files (WIOPF)".  It is automatically installed as part of the installation of these hIOmon software packages and runs as an application upon the computer where it is installed.

+   What is the hIOmon Disk I/O Ranger I/O Trender Display?

The hIOmon "I/O Trender Display" is also included with the hIOmon Disk I/O Ranger Display software.  It runs in conjunction with the hIOmon "Disk I/O Ranger Display" application, which transfers to the I/O Trender Display software component various metrics that it has retrieved.  These metrics are then shown by the I/O Trender Display in accordance with the various configuration options that are provided by the I/O Trender Display.

The hIOmon "Performance Threshold Range Metrics" are displayed by the hIOmon Disk I/O Ranger Display application in a bar-chart histogram fashion.

In contrast, the hIOmon I/O Trender Display can be used to optionally display these I/O metrics within a graphical/chart format.

+   What is the "On-the-Web (OTW)" version of the hIOmon Disk I/O Ranger Display?

hIOmon software such as the hIOmon "Workload I/O Profiler (WIOP)" are software packages for installation upon a variety of supported Microsoft® Windows® operating systems (e.g., Windows 7, Windows 8, Windows 10, Windows Server 2012 R2, Windows Server 2016, etc.).  These packages include the installation of the hIOmon Disk I/O Ranger Display application along with the I/O Trender Display software upon the respective computer.

In contrast, the OTW version of the hIOmon Disk I/O Ranger Display is "online/Internet-based" and runs within your Web Browser.  It allows you to use the hIOmon Disk I/O Ranger Display without having to install the software upon your computer.

The hIOmon Disk I/O Ranger Display OTW effectively enables you to connect to a remote computer in a secure fashion to use the hIOmon Disk I/O Ranger Display software that is installed upon that computer.

The OTW version of the hIOmon Disk I/O Ranger Display is included within the hIOmon "REST API" software package.  The hIOmon REST API web service can be configured to allow access to the associated hIOmon Disk I/O Ranger Display OTW URL.

+   How does the OTW version of the hIOmon Disk I/O Ranger Display differ from the installed version?

The installed application version of the hIOmon Disk I/O Ranger Display:
  • Runs as a Microsoft Windows HTML Application (HTA)
  • Uses the hIOmon Windows Management Instrumentation (WMI) support access to the hIOmon Manager for the retrieval of hIOmon I/O operation performance metrics, to obtain the current hIOmon software status, and to configure the hIOmon software
  • Does not require access to the Internet, but requisite versions of the software can connect to remote computers using the hIOmon REST API support

The OTW version of the hIOmon Disk I/O Ranger Display:

  • Does not run as a Microsoft Windows HTML Application (HTA)
  • Requires a supported Web Browser within which to run the hIOmon Disk I/O Ranger Display OTW software.
  • Optionally requires that Web Browser cookies be enabled in order to save various display configuration options between successive uses of the Disk I/O Ranger Display OTW
  • Does not make use of the hIOmon Windows Management Instrumentation (WMI) support
  • Requires Internet access.  Pop-Ups must also be allowed in order to establish sessions that verify the authorized use of the OTW version of the hIOmon Disk I/O Ranger Display software.

Apart from the basic differences noted above, both versions of the hIOmon Disk I/O Ranger Display provide essentially the same displays, user-selectable display options, etc.  This also applies to the "I/O Trender Display" that is included with both versions.
