Monitor Network Congestion and the Performance of Servers

In this scenario, you want to monitor congestion at two often-used and
mission-critical remote servers. You will send the information that the tracks
collect to your service provider to document the connection's performance.
Two probes monitor each server: one probe tests for optimal performance,
and the other probe tests for minimum adequate performance. What passes
for optimal and minimal performance depends, of course, on your company's
needs and normal network conditions, and you should set the probes' timeout
and rate of failure tolerance accordingly. The commands below merely pro-
vide one example.
One track monitors each probe, creating logs when performance changes, but
does not affect routing.
Follow these steps:
1. Configure the pair of probes for each network point to be monitored. In
this example, you will use HTTP Get probes for testing one key destina-
tion, a remote Web server, and TCP connect probes for testing the second
key destination, a remote email server.
