Change the replication strategy for the OpsCenter keyspace
Using the NetworkTopologyStrategy replication is recommended for the OpsCenter keyspace when running OpsCenter in a multi-datacenter environment.
If the keyspace isn’t already using this strategy, a message appears in OpsCenter prompting you to change the keyspace to use NetworkTopologyStrategy.
-
If the OpsCenter keyspace warning is visible in OpsCenter, expand the warning, and then click Edit the keyspace here.

-
Change the strategy from SimpleStrategy to NetworkTopologyStrategy.

-
Enter the datacenters and replication factor for each datacenter. Click Add Datacenter to add more datacenters.
-
Set the durable_writes option to
True(recommended) orFalse(default).Be careful when setting the durable writes option. When set to
False, data written to the keyspace bypasses the commit log, which could cause data loss. -
Click Save Keyspace.
