As shown in the screen shot
above, "engCenter" is one of the Filter Selections
that is available at the selected hIOmon Manager (which is
running upon the server called "hyperIO2"). All of the filters
within the engCenter Filter Selection correspond to files
accessible by the hyperIO2 server. The engCenter Filter
Selection is maintained by the hIOmon Manager upon the hyperIO2 server. You can click on the
"New" button to define a
new Filter Selection, add the specific filters to be included
within this new Filter Selection, and then click on the
"Save"
button to have the hIOmon Manager at the hyperIO2 server save the
newly defined Filter Selection. Use the "Get" button to
retrieve a previously saved Filter Selection and display its
contents within the Filter Options display; the "Delete" button
allows you to delete a particular Filter Selection at the
selected hIOmon Manager. You can also a "Copy" the
selected Filter Selection to another hIOmon Manager (or make a
copy of the selected Filter Selection with a new name at the same
hIOmon Manager). The "Rename" button allows you to change
the name of the selected Filter Selection, and the
"Refresh" button
lets you refresh the displayed list of Filter Selections available
at the selected hIOmon Manager.
The "engCenter"
Filter Selection is comprised of seven different
filters. Four of the filters are associated with the
"C"
device; the remaining three filters pertain to the "T" drive.
The screen shot above highlights several hIOmon features:
-
You
can use wildcards to specify the files to be monitored (for
example as shown, all files and sub-directories within the
"C:\TEMP" directory). You can also specify a particular
file (e.g., "T:\Dummy.txt").
-
You
can exclude specific files (for example as shown, all file and
sub-directories starting with "C:\TEMP\junk"). Those
filters representing files to be excluded are highlighted in bold.
-
A number of options can be specified for
each
individual filter. You first select the particular filter
whose options you want to set (as shown in the above screen shot
by the highlighted filter "T:\Documents\*"), then click on the
various options available.
For example,
the selected filter can be set such that the hIOmon I/O Monitor will collect
performance information for only read I/O operations, write I/O
operations, or control I/O operations (or combinations thereof) that
are performed against the respective files.
Filter options include the ability to request the collection
of I/O Trace information (i.e., an I/O trace record for each
individual I/O operation) and/or summary
(i.e., aggregated) I/O operation information.
Note:
The "Trace Records"
and "File I/O Summary" options are only available if the
respective hIOmon Licensing Option has been purchased as part
of the hIOmon service subscription fee.
-
The File I/O Summary option
allows you to specify whether the summarized I/O operation information for the
respective file filter is to be collected on a periodic basis, when the file is
closed (or becomes inactive), or on an exception (Alert)
basis. Clicking on the "Options/Alerts" button to the right
of the "File I/O Summary" check box brings up a display (shown
below) that
allows you to specify which of these summarized file I/O
operation performance options is to be used for the selected filter.
-
Process Name
Filters. You can optionally specifically include
and/or exclude those particular processes whose file I/O
operations are being monitored by the hIOmon I/O Monitor.
For example, if the hIOmon I/O Monitor is monitoring all file
I/O operations within the "Windows" directory, you can
optionally specify through a process name filter that all such
file I/O operations performed by the "System(4)"
process be excluded/ignored by the hIOmon I/O Monitor.
Note that you can
specify such process name filters either upon a "global"
basis (i.e., applicable to all filters defined within a Filter
Selection) or upon a "Filter-specific" basis (i.e.,
applicable only to a particular filter defined within the Filter
Selection). And for the "global" process name
filters, you can also optionally specify (upon an individual
global process name filter basis) that "Process Summary"
I/O operation information is to be collected for the respective
process. The "Process Summary" I/O operation
information reflects the summarized (i.e., aggregated) I/O
operation information for all files being monitored by hIOmon and
to which the respective process directed a file/device I/O
operation. As with the File I/O Summary option, you can
specify that a "Process Summary" be collected upon a
periodic basis, when a monitored file for the process is closed
(or becomes inactive), or on an exception (file Alert)
basis.
-
With the "Raw
Device Extended Feature" licensing option, you can also
specify whether "Physical Device Extended
Metrics" are to be collected for the filter; these metrics
represent I/O operation performance information that has been
collected by the hIOmon I/O Monitor at the "physical
device" level within the operating system and which are associated
by the hIOmon I/O Monitor with their related file I/O
operations. Essentially,
these metrics reflect those physical device I/O operations that
were performed so as to satisfy file I/O operations which were
also monitored by the hIOmon I/O Monitor at the associated
file level.
-
You can optionally
specify that a particular
Filter Selection is to be considered as the "default" Filter Selection. hIOmon can be configured so
that the hIOmon Manager will
automatically start its associated hIOmon I/O Monitor and
begin file and device I/O operation performance monitoring using the default File
Selection when the hIOmon Manager is
started.
-
The "Add" and
"Remove" buttons near the bottom of the display allow you to add
or remove filters from the Filter Selection. If the
hIOmon Presentation Client
is running on the same computer as the selected hIOmon Manager, then the
"Browse..." button appears within this display. Clicking on
the "Browse..." button brings up an
"Explorer-type" windows
display of the server's files and directories from which you can select
a file name representing a new filter to be added to the Filter Selection. The
"Copy" button near the bottom of the display
allows you to make a copy of the selected filter with a new
device/file/path name (with all of the associated Filter Options
remaining the same). And the "Rename" button lets you
change the device/file/path name associated with the selected
filter (with all of the other associated Filter Options
remaining the same).
The hIOmon Presentation Client
allows you to quickly and easily specify the particular type of file
and device I/O operation performance information that you want and need.
