Babak Behzad created KAFKA-3241:
-----------------------------------
Summary: JmxReporter produces invalid JSON when a value is Infinity
Key: KAFKA-3241
URL: https://issues.apache.org/jira/browse/KAFKA-3241
Project: Kafka
Issue Type: Bug
Reporter: Babak Behzad
We recently realized that the when JmxReporter$KafkaMbean has some metrics with
the value Infinity, the JSON created is invalid since the string value
"Infinity" or "-Infinity" are not in double-quotes! Here's an example:
{noformat}
{
"name" :
"kafka.producer:type=producer-node-metrics,client-id=producer-1,node-id=node-1",
"modelerType" : "org.apache.kafka.common.metrics.JmxReporter$KafkaMbean",
"request-rate" : 0.0,
"request-size-avg" : 0.0,
"incoming-byte-rate" : 0.0,
"request-size-max" : -Infinity,
"outgoing-byte-rate" : 0.0,
"request-latency-max" : -Infinity,
"request-latency-avg" : 0.0,
"response-rate" : 0.0
}
{noformat}
