4.6.6 Using the Performance Monitor
The performance monitor monitors the hard disk accesses of the DVS
software to the video data. With it you can verify, for example, the sta-
tus of the hard disks of the storage array as well as of certain files on
the array.
This section will explain shortly how to use the performance monitor:
First, it will be described how to prepare the monitor and the DVS soft-
ware for the measuring of the system’s workload. After that follows a
description of how to perform the actual test with a play-out operation.
Preparing the Software and the Performance Monitor
This section explains how to prepare the DVS software as well as the
performance monitor for the measuring of the system’s workload dur-
ing a play-out operation.
Once the placing of the markers is finished, this
button shows the labeling UNMARK ALL. Then you
can remove with it all timeline markers from the
timeline in one step.
The MARK ALL button will not be available
in the I/O Tool because this module pro-
vides no timeline where markers can be
set.
The CLEAR button deletes all entries displayed in
the drop table. Afterwards you may start a new
real-time operation which in turn may report new
drops in the table. This button will be available as
soon as drops are displayed in the drop table and
the real-time operation is finished.
Individual frames missing in an image sequence (clip), i.e. im-
age files that are not present on the storage at all, are not reg-
istered as drops. You can check the consistency of your
material added to the bin with the menu option Check Bin on
the Bin menu (see section “Check Bin” on page 9-19 and sec-
tion “Consistencies of Clips” on page 6-63).
Although the following describes how to use the performance
monitor during a play-out of video data, it can also be used
during a record operation. Then it will measure the workload
when writing files to the storage instead of reading them. A
record can be performed with the I/O Tool (for further infor-
mation see the “CLIPSTER I/O Tool” user guide).
