About this task

View logs in the Recent Log Information pane within the Node details dialog. The Cassandra System Log, Cassandra Debug Log, and OpsCenter Agent Log are available for viewing within OpsCenter monitoring. The most recent 1000 lines of a log are displayed in the log window.

Prerequisites

Viewing logs from within the OpsCenter user interface node details is currently a Labs feature (that is, under ongoing development but available for use).

To enable the feature, locate the opscenterd.conf file. The location of this file depends on the type of installation:

  • Package installations: /etc/opscenter/opscenterd.conf

  • Tarball installations: install_location/conf/opscenterd.conf

Add the following to opscenterd.conf and restart opscenterd:

[labs]
log_enable = True
