Changing logging locations
Logging locations are set at installation.
Generally, the default logs location is /var/log.
For example, /var/log/cassandra and /var/log/tomcat.
For details, see Default file locations for package and Installer-Services installations and Default file locations for tarball and Installer-No Services installations.
You can also change logging locations with OpsCenter Configuration Profiles.
