Description

getting attribute Mean of org.apache.cassandra.metrics:type=ColumnFamily,name=ColUpdateTimeDeltaHistogram threw an exceptionjavax.management.RuntimeMBeanException: java.lang.IllegalStateException: Unable to compute ceiling for max when histogram overflowed

Although the fact that this histogram has 164 buckets already, I wonder if there is something weird with the computation thats causing this to be so large? It appears to be coming from updates to system.local
