1.4 Processing Node Monitors<br />

Used Bytes Level<br />

Busy Processors<br />

Input Buffer Level<br />

Output Buffer Level<br />

Call Bandwidth Level<br />

Calls In Progress<br />

Channels In Use<br />

Measure how much file space is used in the node's disk storage space.<br />

This monitor is useful for models that have Read and Write commands<br />

that change the size of files.<br />

Measure the number of busy processors. For a single processor node,<br />

the result is the utilization of the processor. Frequently the processor will<br />

be busy with short duration tasks and, thus, it is generally desirable to<br />

collect this utilization averaged over a convenient interval.<br />

Measure the input buffer level of the node. Since packets arrive and leave<br />

buffers very frequently, it is generally desirable to collect averaged buffer<br />

levels for plotting.<br />

Measure the output buffer level of the node. Since packets arrive and<br />

leave buffers very frequently, it is generally desirable to collect averaged<br />

buffer levels for plotting.<br />

Measure the call bandwidth allocated through this node. It is useful when<br />

modeling bandwidth-switched calls with call sources, and it gives the<br />

total bandwidth of all the calls using this node.<br />

Measure the number of calls in progress established by the node.<br />

Measure the number of call channels in use by the node.<br />
