A downtime report can show the downtime of one or more selected networks or objects. What contributes to your downtime can be displayed down to the individual monitor level if required. The downtime report item can report three different values, namely downtime, uptime and unknown. Downtime is defined as the total time the monitor was in the alarm state. Uptime is defined as the time the monitor was in a normal state. Unknown is the time Network Monitor did not know the status of the monitor, for example if the Network Monitor service was stopped for a couple of hours. All values are reported as percentages of the report period.
It is also possible to limit the downtime calculations for a period during the day. This is useful if you need to know your uptime only during a certain time. Another advanced option is to limit the downtime calculation to only a limited set of monitors. For example, you could choose to only calculate downtime on your networks and objects by using Ping monitors only.
