A look at our Google Analytics data for the online demo show that users rarely click the ‘Root Cause Analysis’ 
icon. That could mean that this is a relatively hidden feature. We have iterated on showing different icons many times for this particular feature. Looks like users donot find it intutive still.
The Root Cause Analysis (RCA) window helps to drill down from a high level view to a details view. For example, assume you have a business application that is grouped under a monitor group named ‘banking application’. This group may have 2 linux servers, a jboss server and an Oracle database. What an RCA can tell you is that the ‘banking application’ is critical because the disk space on server 1 crossed 95% usage, the jdbc free connections is zero etc…..
The RCA view also gives you the details of individual thresholds that were crossed (and hence making the monitor group critical). You have these at various levels :
1) A metric level inside a monitor
2) A monitor level
3) A monitor group level
4) A monitor category level : this can be seen in the Home tab > Monitors bashboard view. Here you will know which all application servers are critical.
The below are some of the clickable icons in the web client wrt RCA .. .
Hope more people read this and get enlightened . Any suggestions 💡 to improve this are welcome.
