Setup Log Collection

AxonOps dashboards provides a comprehensive set of charts with an embedded view for logs and events. The goal is to correlate metrics with logs/events as you can zoom in the logs histogram or metrics charts to drill down both results.

Log and event view is located in the bottom part of that page that you can expand/collapse with the horizontal splitter.

Note: Currently this configuration is shared accross all the clusters but we will provide a dedicated configuration (per cluster) soon.

The default setup will collect Cassandra system.log, axon-agent.log and axon-java-agent.log. You can update the path of your cassandra system.log if it's located in a different folder by updating the filename field. The newlineregex is used by the log collector to handle multilines logs. Default newlineregex should be ok unless you've customized cassandra logs.

Once all is setup and submit is pressed, you should see events from the agents and logs from the log files you've specified.
