How much bandwidth does uptime monitoring use?

This can be easily calculated for a given host:

1. Determine the bandwidth used for each sensor in use:

HTTP:
Check the size of the page you are monitoring, and add around 10%

Other sensors:
Around 2.0 kB per test.

2. Add the bandwidth used for each sensor together to create a total.

3. Calculate the number of test cycles conducted each day:
= 1440 / (monitoring frequency in minutes)

4. Multiple the results of [2] and [3] to arrive at the total bandwidth used each day.
