Opscenter stores a lot of information regarding all aspects of your
cluster, such as OS, cluster, keyspace and individual table metrics, after
a set period of time these granular data point are rolled up into
aggregates. This is what you are seeing in the logs.

Is there a way to disable it


Yes, you could stop monitoring your cluster with OpsCenter or store less
granular data, see the docs for all the options to can tune:
http://www.datastax.com/documentation/opscenter/5.0/opsc/configure/opscConfigureDataCollectionExpiration_c.html

and whats the impact


The only impact is that you will either have less granular metric data to
work with or none at all (from OpsCenter)
