Tools enabling Real User Monitoring, or RUM (also known as End User Experience, or EUE, and some similar things) have proliferated hugely over the last 10 years, to the point there are now countless hopeful vendors jostling for contention.
RUM certainly adds a powerful additional perspective to external monitoring, and whilst it does not replace “traditional” active (synthetic) testing – they are complimentary – it can dramatically improve some aspects of end-user performance visibility, particularly for companies with a broad international reach.
As always, a crowded marketplace can contain sheep as well as goats. I thought that it may be useful to share some musings on RUM product distinctions. The relative importance of each will depend on particular circumstances, and there is a degree of functional convergence occurring, at least among the players who are carving out significant market share (and who clearly wish to be around for the long-term). Hopefully these will be helpful to the uninitiated who are considering a purchase decision.
