The UX Block IO object provides counters for monitoring the processing activity on UNIX systems.
For counters that accept a block IO device instance, block IO device names are available in the Operator Console. For example, to monitor the average number of kilobytes read per second from the block IO device scanner, type:
UX Block IO|Kilobytes Read/s|scanner
To monitor a counter for all block IO devices instead of a particular device, such as average number of transfer operations waiting, type:
UX Block IO|Average # of Trans. Waiting|_Total
The following table describes the counters for the UX Block IO object.
