Measures reported by CassStrgeTest
This test reports the current size of the target Cassandra Database node and the rate at which data is growing. This test also reveals the rate of unhandled exceptions on the database node. Using this test, administrators can figure out how well the database node is growing as well as capture and rectify the unhandled exceptions before the data becomes stale!
Ouputs of the test: One set of results for the target Cassandra Database node that is being monitored.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Node_size |
Indicates the current data size of the target node. |
MB |
|
| Growth_rate |
Indicates the rate at which data is growing on the target node. |
MB/sec |
|
| Exceptions |
Indicates the rate at which unhandled exceptions occurred on the node during the last measurement period. |
Exceptions/sec |
Ideally the value of this measure should be 0. A sudden/gradual increase of this measure indicates that too many unhandled exceptions have occurred. Administrators may need to troubleshoot the unhandled exceptions by checking the Errors and Fatal measures reported by the CassLogTest test. |
