DMS Dashboard Templates

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. This dashboard visualizes key metrics extracted from DMS rebalancing logs, including the total rebalancing consumer groups, total rebalances, number of rebalances per consumer group, rebalancing reasons, and group details.
