The Usage Display Tab is a convenient tool to continually monitor critical resources that can effect
M300 DAS performance. This information has been integrated into the M300 main console to make
that information easily available even during in flight data acquisition. The two resources monitored
are System Memory (RAM) and available Hard Disk Space (Disk).
After each time the M300 is used to collect data it’s recommend to copy the data to another source
(USB drive). Also, the user must check the integrity of the data via playback. If the disk space is
getting low, the user must remove some with caution! Any files removed in the QNX 4 OS can’t be
un-deleted! The user must make sure there is sufficient space for the M300 to run and collect all
necessary data (*.sea and ASCII files).
The three key statistics reported on the System Ram and Disk Space are total available capacity of the
resource, total resource used, and free or available resource. All information is represented in
Megabytes and is displayed both numerically and in graph form for a quick assessment of resources.
Total
The total amount of resource (RAM or DISK size) installed in the system.
Used
The amount of system wide resource (RAM or DISK space) currently in use.
Free
The amount of system wide resource (RAM or DISK space) available to any resource.
GraphicalBar
Provides a quick snapshot of the current status of the resource. When the resource becomes 95%
used, it will change from green to yellow, and then to red at 98%.
