This page provides documentation access for Cassandra app

The Cassandra app is a unified logs and metrics app that helps you monitor the availability, performance, health, and resource utilization of your Cassandra clusters. Preconfigured dashboards provide insight into cluster health, resource utilization, cache/Gossip/Memtable statistics, compaction, garbage collection, thread pools, and write paths.

Log Types

The app supports Logs and Metrics from the open-source version of Cassandra. The App is tested on the 3.11.10 version of Cassandra.

Cassandra has three main logs, system.logdebug.log, and gc.log which hold general logging messages, debugging logging messages, and java garbage collection logs respectively.

These logs by default live in ${CASSANDRA_HOME}/logs, but most Linux distributions relocate logs to /var/log/cassandra. Operators can tune this location as well as what levels are logged using the provided logback.xml file. For more details on Cassandra logs, see this link.

The Sumo Logic App for Cassandra supports metrics generated by the Jolokia2 plugin for Telegraf. The app assumes prometheus format Metrics.
