What's new in Streams Messaging Manager
Learn about the new features of Streams Messaging Manager in Cloudera Runtime 7.2.9.
- Added timestamp to SMM UI logs
SMM UI logs have timestamps.
- Kafka supports producer metric whitelisting
The feature allows producerMetrics to be whitelisted based on a whitelist property that should contain a regex with the allowed
client.ids.In order to enable the feature, set the following properties within
Kafka Broker Advanced Configuration Snippet (Safety Valve)for
- producer.metrics.whitelist=regex containing the whitelist for the desired producer's client.ids
This regex uses the simple java
java.util.regex.Patternclass to compile the regex, and uses the
match()method on the
client.idto determine whether it fits the regex or not.
This feature deletes all the producer timeSeries entities from Service Monitor (CM metricsStore) that do not match the regex.Also this feature filters the metrics within Kafka itself, so producerMetrics that do not match the regex, would not be reported by the
/api/metricsendpoint in the Kafka brokers. Both CM and Kafka use the same Java class and method to filter the metrics.
