By the time VCS decides to fail over, OME has already emailed you the root cause analysis and a screenshot of the memory leak that caused it. One of the coolest features hiding in the VCS OME stack is the Heat Map and Cross-Stack Correlation .

OME’s secret weapon is the engine. Have you ever had a junior admin edit llttab incorrectly and split the cluster brain? OME scans every node every 15 minutes. If one server has a different kernel parameter than the other three, OME flags it.

OME acts like a detective with a warrant. It pulls logs from VCS, the application agent, and the OS simultaneously. It visualizes exactly where the latency enters the stack. Did the VCS agent time out? Or did the underlying LUN actually freeze for two seconds?
