1.We would like to confirm how to calculate the size of KeySpace OpsCenter that is created on each Cassandra node.
FYI, in the customer’s test environment, KeySpace size have been increasing day by day.
2.According to the document of opscenter, it is said that old data is deleted by aging process. the aging is configurable by the setting in opscenterd.conf.
# Expire 1 minute data points after 7 days
#1min_ttl = 604800
# Expire 5 minute data points after 4 weeks (28 days)
#5min_ttl = 2419200
# Expire 2 hour data points after 365 days
#2hr_ttl = 31536000
What is the relation between “Column Family” that is included OpsCenter Keyspace and the above keys?
