Unfortunately OpsCenter doesn't currently support running behind a proxy,

Thanks everyone. We always appreciate constructive criticism.
Regarding what OpsCenter collects, we completely agree it should be
documented more clearly. You can expect to see an update to the
documentation later today. I will update this thread once that goes live.
Regarding notifying the user
OpsCenter collects anonymous usage data and reports it back to DataStax.
For example, number of nodes, keyspaces, column families, etc. Stat
reporting isn't required to run OpsCenter however. To turn this feature
off, see the docs here (stat_reporter):

The overhead for column families was greatly reduced in 0.8 and 1.0.
It should now be possible to have hundreds or thousands of column
families. The setting 'memtable_total_space_in_mb' was introduced that
allows for a global memtable threshold, and cassandra will handle
flushing on its own.

The OpsCenter agents report metric data to the main OpsCenter process
which processes it and writes data into the cluster. So yes, the main

I believe you are mis-understanding what cleanup does. Cleanup is used
to remove data from a node that the node no longer owns. For example
when you move a node in the ring, it changes responsibility and gets
new data, but does not automatically delete the data it used to be
