In OpsCenter - Cluster -List view - the data size is not showing up correctly. The OS Disk Usage for the Cassandra Data File system shows 901GB but on the List view it shows up as only 548GB. Why is the Opscenter List View not showing the correct file size?

Opscenter - Cluster -List view not showing the correct size(3 posts) (3 voices)
We are also seeing the same symptomp in Ops Center.
After restarting the opscenter agent in one node, the disk usage of that one node shown in OpsCenter is correct again.
It appears that the agent is not picking up any growth in disk usage since it was started.
The agent.log does not have any obvious error messages. There are normal messages like this:
INFO [qtp1925049412-39] 2012-12-31 09:08:44,710 HTTP: :get /os-metric/disk-space - 200
We are using DSE 2.1.1, OpsCenter 2.1.2
This is most likely caused by a known issue with errors in data collection causing new data from being pushed. Unfortunately, that also causes errors to not be displayed properly, making it harder to diagnose. This should be fixed in the next patch version of OpsCenter (2.1.3), which will be out in the near future. Keep an eye on our dev blog for that announcement.
