Contrail Analytics Performance Tuning
=====================================
For large installations, the following changes are required to achieve better performance of contrail database.
By default, the analytics_ttl values are set to -1. We recommend changing the default number to ensure the best performance in highly scaled out environments. An example configuration is as follows:
#. /etc/cassandra/cassandra-env.sh
::
-JVM_OPTS="$JVM_OPTS -XX:MaxTenuringThreshold=1"
+JVM_OPTS="$JVM_OPTS -XX:MaxTenuringThreshold=30"
#. /etc/contrail/contrail-collector.conf
::
analytics_config_audit_ttl=2160
analytics_statistics_ttl=24
analytics_flow_ttl=2
Note: Please restart the supervisor services ( supervisor-­database, supervisor­-analytics) after making these changes.
