public class SimpleMeterHealthCheck
extends com.codahale.metrics.health.HealthCheck
```
Very simple health check that checks if a Meter has any errors in the last 15 minutes, calculated using the 15-minute rate from the meter. The returned results are built using HealthCheckResults so they contain a "severity" detail.

HealthCheckResults

Implementation Note:

If the Meter from Metrics library uses exponentially-weighted moving averages, it is actually not trivial to compute an exact number of errors in the last N time units. Here, this is using the 15-minute rate from the supplied meter and using that to estimate the number of errors. See specifically MovingAverages and Meter(MovingAverages).
