The
caveat is that if you are tracking network performance, you must also take into account all the extra
traffic being generated by running it remotely; so, for the case of network utilization tracking, it would
make sense to log that locally on the server instead.

Data Collector Sets
A data collector is a component used to gather performance data about your server. For
example, a processor data collector gathers information about the processor, such as its
utilization. One or more data collectors can be grouped together to form a data collector
set. Data collector sets can be used to define groups of data points for which you are
interested in gathering data. You can run these data-gathering sessions on an ad hoc or
scheduled basis and then view the data as reports through the Reliability and Performance
Monitor console. This eases the task of gathering performance data. For example,
you can create a data collector set to encompass a number of standard performance metrics
such as CPU and memory utilization, as well as a few Terminal Services??“related
counters such as active and inactive sessions. You can then schedule this data collector
set to run from 6:00 p.m. to 6:00 a.m. so that you can track the performance and utilization
of the terminal server during nonbusiness hours. This is an overly simplified example,
but I??™m sure you get the idea.
