Any vSphere infrastructure, once deployed, needs to be monitored for performance during its life cycle. Continuous monitoring helps configure the infrastructure in a manner that maintains optimum performance to meet the business needs, which can bring cost savings.

Unlike other monitoring tools, vROPS does what VMware calls predictive analysis, which learns what is normal in an environment over time and provides recommendations, facilitates capacity planning, and allows policy-based automation. It can also monitor/manage environments. It is the tool that most infrastructures want to use to be efficient in IT operations.
