There are many tools available in market for monitoring
application software and hardware resources in pre production and production
environment. Some have the diagnostics capabilities where we can deep dive
straight into the bottleneck and figure out the root cause while some are used
passively just to monitor resources. Some are agent based i.e. they will
communicate with the server where agents specifically designed to understand
server platform are installed and correlate those readings and present them to
the user, while some are agent less which do not require any installation on
the server side.
HP Sitescope is agent less resource metrics monitoring tool
which is one of the most easily deployable monitoring tool around. The main
purpose this tool is to check application availability and performance of
application and infrastructure in distributive application environment.
