hIOmon Add-Ons Support

Big Picture

The "hIOmon Add-Ons" are auxiliary software utilities that are targeted towards specific tasks and which leverage the extensive functionality of the hIOmon File I/O Performance Monitor software.

One such task is characterizing the I/O operation performance of specific files (and their associated logical and physical devices).  Another specific task is determining the actual file I/O operation performance impact incurred by file fragmentation.  The hIOmon Add-Ons for each of these tasks are briefly described below; complete information can be found within the "hIOmon Add-On User Guide" document.

The hIOmon Add-Ons make use of the various interfaces provided by the hIOmon File I/O Performance Monitor software.  The hIOmon WMI Support, for instance, is used to configure and manage the operation of the hIOmon software.  Similarly, the hIOmon export capabilities (such as the CSV-based "hIOmon Manager Export File") are used to gather the I/O operation performance metrics collected by hIOmon for subsequent analysis by the hIOmon Add-On utilities.  Please see the “hIOmon User Guide” document for a detailed description of the variety of interfaces provided by the hIOmon File I/O Performance Monitor software.

NOTE that both of the hIOmon Add-Ons described below are included as part of the hIOmon software package!

hIOmon Device and File I/O Performance Analysis Add-On

The hIOmon "Device and File I/O Performance Analysis Add-On" enables you to characterize the I/O operation performance of specific files (and their associated logical and physical devices) that are of particular interest to you. This I/O operation performance characterization can highlight key metrics, including read and write I/O operation counts, I/O operation (IOPS) rates, amount of data transferred along with MB/s rates, average and maximum response times, random and sequential access counts, average and maximum queue lengths, system file cache "hit" and "miss" statistics, etc.

Through the use of the hIOmon "Device and File I/O Performance Analysis Add-On" you can now quickly and easily perform such file (and device) I/O operation performance characterizations, moreover based upon empirical metrics that have been collected by hIOmon and which reflect the normal, everyday use of your very own files (even within production environments).  In addition, this Add-On provides charting and graphing support (through the use of the Microsoft® Office Excel program) that enables you to perform file and device comparisons, various "Top Ten" rankings, "Hot Spot" analyses, problem diagnosis, capacity and performance analyses, and much more.

Please refer to the hIOmon "Device and File I/O Performance Analysis Add-On" description page for additional information about this hIOmon Add-On.

hIOmon Fragmented File I/O Operation Metrics Analysis Add-On

The hIOmon "Fragmented File I/O Operation Metrics Analysis Add-On" enables you to determine the actual file I/O operation performance impact incurred by file fragmentation, based upon empirical metrics that have been uniquely collected by hIOmon and which reflect the actual file I/O operations performed through the normal, everyday use of your very own applications and associated files!  Moreover, no file, application, or operating system changes are required!
