I have been running health checks for decades. BigCharts server is happy is the first. MarketWatch is also happy.

The health” of a process is a spectrum. What we’re really interested in is the quality-of-service — such as how long it takes for a process to return the result of a given unit of work and the accuracy of the result.

Getting more precise with checks, not simple up and down, is definitely a good improvement.
