The hIOmon WIOP and WIOPF both support the option of displaying a broad set of summary I/O operation metrics that have been saved within a hIOmon Manager Export File. These metrics include the various hIOmon "Performance Threshold Range Metrics". The hIOmon Manager Export File is a "Comma-Separated-Values (CSV)" formatted file, which can also be used as an input file for an Excel worksheet, a database, etc.
The hIOmon Disk I/O Ranger Display can retrieve the summary metrics from a selected hIOmon Manager Export File. The metrics are then shown within the "Main Display" in accordance with the display options that have been selected within the "Settings" configuration window (see, for example, the WIOP display options). Note that these metrics can also be optionally displayed within the hIOmon "I/O Trender Display".
Overall, the metrics retrieved from hIOmon Manager Export Files are shown by the hIOmon Disk I/O Ranger Display and the hIOmon I/O Trender Display in a manner identical to the display of real-time I/O operations metrics (e.g., the same display options for both real-time and historical I/O operation metrics).
|The hIOmon WIOP and WIOPF also support retrieving I/O operation event trace data from a Microsoft® "Event Tracing for Windows (ETW)" input log file (see "Displaying I/O Metrics from an ETW Input Log File" for details).|
As illustrated by the annotated screenshot below, the steps required to retrieve and display summary I/O metrics from a hIOmon Manager Export File are:
After first performing the two steps above, click on the "Browse..." button (shown within the screenshot below). Then select the particular hIOmon Manager Export File whose I/O operation performance metrics are to be retrieved for display.
hIOmon Manager Export Files are typically located within the "Support\hIOmonGr\ExportFiles" directory where the hIOmon software was installed. Regardless, you can also select a hIOmon Manager Export File that resides within some other folder.
NOTE: A "List Remote" button (or "List Files" button with the "On-The-Web (OTW)" version of the hIOmon Disk I/O Ranger Display) is additionally displayed when connected to a remote computer using the hIOmon REST API. Click on this button to display a drop-down list box that appears above upon the "Retrieve metrics from file:" line. As indicated within this drop-down list box, select a hIOmon Manager Export File from the list. These hIOmon Manager Export Files are present upon the remote computer within the "...\hIOmonGr\ExportFiles" folder where the hIOmon software is installed. The hIOmon Disk I/O Ranger Display will retrieve from the remote computer (using the hIOmon REST API) the metrics contained within the selected hIOmon Manger Export File.
As highlighted within the screenshot below, the "Retrieve metrics from file:" text box displays the hIOmon Manager Export File from which I/O operation performance metrics are to be retrieved. This text box is automatically updated with the full file path name of the hIOmon Manager Export File chosen by means of the "Browse..." button. Any text manually entered into this text box is ignored.
The hIOmon Disk I/O Ranger will extract the names of the monitored items from the selected hIOmon Manager Export File. These names will be placed within the drop-down list box containing the names of the monitored items (e.g., the "Device names" in the screenshot above).
Simply select the monitored item of interest from the drop-down list box, select the particular I/O metric types to be included within the display, and then click on the "OK" button to display the retrieved summary I/O metrics associated with the selected name.
As highlighted within the screenshot below, a "Coalesce" button appears within the "Settings" window when the "Retrieve from hIOmon Manager Export File" checkbox is selected. Clicking this button will aggregate (combine) the existing hIOmon Manager Export Files. Please note that this option is not supported by the OTW version of the hIOmon Disk I/O Ranger Display.
The export files are coalesced in the following fashion:
Similarly, a "DTSdevices_Daily" export file and a "Processes_Daily" export file are generated from the aggregation based upon a daily basis.
Similarly, a "DTSdevices_Totals" export file and a "Processes_Totals" export file are generated from the aggregation based upon an overall totals basis.
|Note that the "Processes_Totals" export file contains a row for each process instance (i.e., each separate execution of an application will result in an individual process instance).
A "Processes_Totals_PIDless" export file is also generated; this export file reflects the combined total of all process instances for the same application.
The resulting coalesced export files can be used as a hIOmon Manager Export File input source for metrics display by the hIOmon Disk I/O Ranger Display.
|The Coalesce feature enables a simple and easy way to view historical displays for an individual device or application upon either a daily or overall totals basis.
Moreover, you can view the respective "I/O Profile" for each of the individual runs of the same application as well as for the application overall (i.e., all runs combined).
And you can perform this coalescing by yourself at the click of a button – and with no need to send your metrics to hyperI/O or elsewhere to perform the coalescing or report generation!
