hIOmon Add-Ons Support

Big Picture

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

Such tasks include characterizing the I/O operation performance of specific files (and their associated logical and physical devices), assessing the "I/O profile" of your particular applications, and determining the actual file I/O operation performance impact incurred by file fragmentation.  Support for the IBM® Tivoli® Monitoring solutions is also provided by the hIOmon Add-Ons.  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 several of 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 all 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, physical device I/O operation activity, 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 and tutorial for additional information about this hIOmon Add-On.

Process I/O Performance Analysis Add-On

The hIOmon "Process I/O Performance Analysis Add-On" enables you to quickly and easily configure the hIOmon software so as to collect "summary" (i.e., aggregated) file and device I/O operation performance metrics for those particular processes that you select.  The collection of "Physical Device Extended Metrics" along with the export of the collected I/O operation performance metrics to a “hIOmon Manager Export File” can also be optionally configured.

In addition, this Add-On enables use of the hIOmon Microsoft® Office Excel template/macros that can be optionally used to easily coalesce the process I/O operation performance metrics that have been exported to the "hIOmon Manager Export File", which is a Comma-Separated-Values (CSV) disk file to which the hIOmon Manager can directly export/save a specific set of I/O operation performance metrics that have been collected by and retrieved from the hIOmon I/O Monitor component.  The hIOmon Manager Export File can then be used by the hIOmon Excel template/macros to generate various charts and graphs based upon the metrics contained within the export file.

The hIOmon "Process I/O Performance Analysis Add-On" further extends the capabilities of the hIOmon "Device and File I/O Performance Analysis Add-On" by enabling you to limit the collection of file and device I/O operation performance metrics to only those particular processes that are of interest to you.

This unique Add-On provides a quick and easy way to help you assess and verify the particular "I/O profile" of your specific processes/applications in normal, everyday use and in production environments.

hIOmon Add-On Support for IBM Tivoli Monitoring

The hIOmon Add-On "Support for IBM Tivoli Monitoring" enables IBM Tivoli Monitoring solutions access to the summary file and device I/O operation performance metrics that are uniquely collected by hIOmon upon an individual file, device, and/or process basis for those specific files, devices, and processes of particular interest to you.  These empirical metrics reflect the actual file and device 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!

Once retrieved by the IBM Tivoli Monitoring components, these hIOmon metrics can then be viewed, graphed/charted, monitored for specific thresholds (i.e., "situations"), and used for trending analysis, capacity planning, service level agreement (SLA) monitoring along with a variety of other enterprise management tasks supported by the IBM Tivoli Monitoring solutions.

Please note that the hIOmon Add-On "Support for IBM Tivoli Monitoring" has successfully met the IBM specifications for validation as "Ready for IBM Tivoli software" and is included within the IBM Tivoli "Open Process Automation Library (OPAL)".  Moreover, IBM Tivoli Monitoring is the first enterprise solution of its type to retrieve and leverage the unique empirical metrics captured and made available only by hIOmon.

Please refer to the hIOmon "Add-On Support for IBM Tivoli Monitoring" description page for additional information about this hIOmon Add-On; the "hIOmon Add-On Support for IBM Tivoli Monitoring User Guide" document also provides detailed information specific to 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!

Please refer to the hIOmon "Fragmented File I/O Operation Metrics Analysis Add-On" description page and tutorials for additional information about this hIOmon Add-On.
