---------------------------------------
Summary: Possible ArithmeticException in Processor Status
Descriptor Value Reducers
Key: NIFI-15076
URL: https://issues.apache.org/jira/browse/NIFI-15076
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: David Handermann
Assignee: David Handermann
The ProcessorStatusDescriptor enumeration has ValueReducer implementations for
percentage calculation of several metrics, include CPU usage and Garbage
Collection. The ValueReducer implementations calculate a percent based on time
spent in nanoseconds after converting nanoseconds to milliseconds. For
nanosecond values less than 1000, the TimeUnit.MILLISECOND.convert() method can
return 0, resulting in an ArithmeticException due to attempted divide by zero.
