vs on "Extracting performance metrics from OpsCenter tables"

Hi,

I would like to query the OpsCenter tables and download the data [for E.g: System utilization such as CPU/Memory/Disk] during insert heavy workloads. Is there some documentation that talks about what the column names/data mean. From schema it is evident that the comparator used is 'IntegerType' but what data does the column name hold? Similarly, the default_validation_class is 'BytesType'. How can this data be deserialized to view human understandable information?

As an example to better understand my question:

The 'rollups60' column family has the key 'getDiskUsagePercent-D:'
and the column - value have the following data:

column value
---------- --------
776517487 @\xe9Y\xb5
776517547 @\xe9Y\xb5

I would like to know what '776517487' means and how do I decode '@\xe9Y\xb5'

I am using the Community version of DataStax Cassandra. Also, is there some free tools available that already do this? I believe the enterprise edition provides a mechanism to achieve this but there is no option for community edition.

Thanks,
VS
