Since the beginning our core business is focused in IT optimization, while we were growing in experience and gaining more and more knowledge about systems behavior and their main bottlenecks, Crossjoin realized there was no tool in the market which could help us on our monitoring and measurement needs. Using our internal resources and expertise, we built our own tool – X-Viewer.

X-Viewer is used today in several projects for KPI calculation and monitoring as well as on customer site implementations for their own operational support teams being able to take advantage of powerful monitoring and analytic dashboards of their systems. 

Each new project is a new challenge and We Like Good Challenges.
