Description

rate metrics for example jvm.JvmMetrics.GcTimeMillis._rate some times give value as Infinity. This is incorrect.

For example invoking below URL returned Infinity along with other values

http://HOST_PORT/ws/v1/timeline/metrics?metricNames=jvm.JvmMetrics.GcTimeMillis._rate&precision=seconds&grouped=true&startTime=1686815115333&appId=hbase&endTime=1686815945333
 
Output:

1686796983505:679
1686797040051: 0.8214285714285714
1686797040144:"Infinity"
1686797042427:55
