UDP- (User Datagram Protocol) UDP is a protocol within the TCP/IP protocol suite that is used in place of TCP when a reliable delivery is not required. For example, UDP is used for real-time audio and video traffic where lost packets are simply ignored, because there is no time to retransmit. If UDP is used and a reliable delivery is required, packet sequence checking and error notification must be written into the applications. For more information go to our home page.

UPS Monitoring- (Uninterruptible Power Supply) Backup power used when the electrical power fails or drops to an unacceptable voltage level. Small UPS systems provide battery power for a few minutes; enough to power down the computer in an orderly manner. Sophisticated systems are tied to electrical generators that can provide power for days. A UPS system can be connected to a file server so that, in the event of a problem, all network users can be alerted to save files and shut down immediately. An "online UPS" provides a constant source of electrical power from the battery, while the batteries are being recharged from AC power. A "standby UPS," also called an "offline UPS," normally draws current from the AC outlet and switches to battery within a few milliseconds after detecting a power failure.

Uptime Monitor- Uptime Monitor is an easy to use network monitoring and event-based scripting utility. Among the many checks it can do: it can monitor any Winsock service, ping a host, check if an NT service/process is running, check the available disk space on a server, retrieve an URL, check your database engine, and more. When it detects a down condition it can alert you in a variety of ways, including sending you an email saying what's down or paging you with a numeric or alphanumeric warning. When used in conjunction with a SensorArray, you can automate event based actions using it's easy scripting feature. Uptime Monitor also supports host dependency and can be easily queried using a telnet client and/or a web browser. For more information go to our Administrative Tools page.
