Real user monitoring

Real user monitoring (RUM) is a passive monitoring technology that records all user interaction with a website or client interacting with a server or cloud based application. Monitoring actual user interaction with a website or an application is important to operators to determine if users are being served quickly, error free and if not which part of a business process is failing. Software as a service (SaaS) and application service providers (ASP) use RUM to monitor and manage service quality delivered to their clients. Real user monitoring data is used to determine the actual service-level quality delivered to end-users and to detect errors or slowdowns on web sites. The data may also be used to determine if changes that are promulgated to sites has the desired effect or causes errors.
Organizations also use RUM to test website or application changes prior to deployment by monitoring for errors or slowdowns in the pre-deployment phase, they may also use it to test changes within the production environment, or to anticipate behavioural changes in a website or application. For example a website may add an area where users would be likely to congregate before moving forward in a group (test takers logging into a website over twenty minutes and then simultaneously beginning a test for example), this is called rendezvous in test environments. Changes to websites such as these can be tested with RUM. As technology shifts more and more to hybrid environments like cloud, fat clients, widgets and apps it becomes more and more important to monitor from within the client itself.
Passive monitoring can be very helpful in troubleshooting performance problems once they have occurred. Passive monitoring differs from synthetic monitoring with automated web browsers in that it relies on actual inbound and outbound web traffic to take measurements.
