What is Network And System Uptime?

The term "uptime" is used to determine the time a computer system has been functional. In network terms it is defined by the availability of a server, device or site. In individual computer terms it is defined by the reliability and stability of the individual sytem. Uptime is most often measured in percentages, so an uptime of 90% for a day would mean that the system worked properly for 1296 minutes (21.6 hours).

Why Uptime Monitoring is Important!

Networks require several reliable devices in order to work properly. Uptime monitoring software controls and monitors the availability of each single device and alerts the administrator when a system fails - usually through email or SMS.

Uptime monitoring software can also be used to determine where issues may arise in future within a network and to proactively monitor the activity within said network, allowing administrators to balance loads or to consider purchasing options and plan upgrades. The simplest way is to use PING sensors at specified intervals. Good monitoring solutions offer many more sensor types for uptime monitoring so that services, websites, and applications can also be checked for uptime statistics.
