“Computer monitoring software enables systems and
applications of all kinds to be watched autonomously, so that the
state of a system is continuously known. If the hardware, software,
or the operating system is not functioning properly, the system
administrator needs to be alerted at the earliest opportunity to
ensure fast problem resolution. Using monitoring software,
technical staff can often take remedial action at the first sign of
a problem, before business processes, end-users, or customers are
even aware that there is an issue.“There are a number of different elements that need to be
monitored in an organisation’s mission-critical IT infrastructure.
These include network protocols, applications, services including
remote services, daemons, servers, and the network infrastructure
itself. A monitoring tool needs to have a large feature set if it
is to be a one stop solution.“It is common for monitoring solutions to be released in open
source and proprietary versions, with the open source version
typically offering basic IT monitoring capabilities, and the
paid-for software adding additional functionality.”
