We are a web-based business with hundreds of clients and dozens of servers. To provide quality service, we need 99.99% uptime and the option to anticipate equipment chargeability. Using Semonix as our support provider, we are instantly informed of equipment failures (e.g. when a mirror disk malfunctions), peak loads, shortage of hard disk space, or even equipment overheating, regardless of what operating system or server software is used. The risk of serious problems that may cause equipment downtime is minimized, and that's exactly what we need. To a large extent, we have chosen Semonix to monitor our servers because they are partners with Nagios Enterpises, which says a lot about their professional level in IT and monitoring. It also helps that they use open-source solutions that are safe and free of charge.
