DMS Dashboard Template

DMS for Kafka is a message queuing service using open-source Apache Kafka. It provides Kafka instances with isolated computing, storage, and bandwidth resources. Rebalancing logs record rebalancing details, including the time, reason, and triggering client of rebalancing.

LTS provides a one-stop wizard to collect DMS rebalancing logs. It also supports multi-dimensional analysis and structuring, and offers a dashboard for DMS rebalancing logs. The dashboard displays the number of rebalancing consumer groups, number of rebalances, number of rebalances for consumer groups, rebalancing reasons, and group details of DMS rebalancing logs.
