1.5 Network Device 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 network device’s disk storage<br />

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

commands that change the size of files.<br />

Measure the number of busy processors at any time. For a single processor<br />

network device, the result is the utilization of the processor. Frequently<br />

the processor will be busy with short duration tasks and, thus, it is<br />

generally desirable to collect this utilization averaged over a convenient<br />

interval.<br />

Measure the input buffer level of the network device. Since packets arrive<br />

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

averaged buffer levels for plotting.<br />

Measure the output buffer level of the network device. Since packets<br />

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

averaged buffer levels for plotting.<br />

Measure the call bandwidth allocated through the network device. It is<br />

useful when modeling bandwidth-switched calls with call sources, and<br />

it gives the total bandwidth of all the calls using the network device.<br />

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

device.<br />

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