Do metrics for detecting clients from old versions actually exist? Or is Gwen making features up? This and more useful advice is coming up on today's episode of Ask Confluent.

- The Java property that will refresh DNS cache frequently: java.security.Security.setProperty(“networkaddress.cache.ttl” , “60");
- Improvements to DNS lookups in Confluent Platform 5.1.2 (Apache Kafka 2.1.1):
- More reasons to upgrade to Confluent Platform 5.1.2
- Monitoring clients with old versions:
- KIP-188 has lots of important new metrics
- If you are worried about “down-conversion” as discussed in Ask Confluent #5, you want to monitor: MBean: kafka.server:type=BrokerTopicMetrics,name=FetchMessageConversionsPerSec,topic=([-.\w]+)
- KIP-188 also added a metric for temp memory usage (memory used for conversion and compression) that can be useful
- In KIP-272, we’ve added version tag to request metrics, so you can see how many requests per sec you get from each version
