Key Metrics Every Cassandra User Should Monitor

Sysdig emphasizes the importance of monitoring key metrics for effective management of Cassandra clusters, drawing from their own experience using Cassandra in Sysdig Cloud infrastructure. Key metrics include read/write requests and latency, disk usage, CPU percentage, network bytes activity, file bytes, heap usage, garbage collection times, hinted handoff pending, and compactions. Sysdig Cloud offers a comprehensive monitoring solution by integrating these metrics into a single dashboard for easy analysis, enabling users to quickly identify performance issues by segmenting data by cluster or node. An example is given where Sysdig Cloud's dashboard helped resolve a compaction backlog issue by identifying a single node's configuration problem, leading to a quick resolution and the setup of an alert to prevent recurrence. This illustrates Sysdig Cloud's ability to provide granular visibility and streamline troubleshooting through automatic correlation with application and infrastructure metrics, even in containerized environments.
