How to rebalance the data
This topic contains instructions on how to rebalance the data across the Security Event Manager hosts. The data is balanced automatically by default. However, in the circumstances such as a host failure, reset, or replacement, data may get skewed. The Data balance Check in Cluster Manager > Monitor > Health periodically checks for data balance and fails if the data skews high. The built-in Data Rebalance (All) job can be used to rebalance the data.
Maintenance window By default, the data will be unavailable during the run to ensure data integrity. Choose a maintenance window when the log receiving rate is low. |
To rebalance the data:
- Go to Cluster Manager > Jobs and click Create Custom Job.
- Select Data Rebalance (All) and Schedule “Manual”, then click Create.
- In the Jobs table, locate the Data Rebalance (All) row, and click Run in Actions. Allow approximately 1 hour for the job to execute, depending on the data size.
- After the job is finished, go to Cluster Manager > Monitor > Health. If the Data balance Check status is Failed, click Run Test to rerun the test. Ensure the test status is Success.
