The VMware Aria Operations for Logs virtual appliance uses a minimum of 100 GB of storage for incoming logs.
When the volume of logs imported into VMware Aria Operations for Logs reaches the storage limit, old log messages are automatically and periodically retired on a first-come-first-retired basis. You can increase the storage limit by adding more storage to the VMware Aria Operations for Logs virtual appliance. See Increase the Storage Capacity of the VMware Aria Operations for Logs Virtual Appliance.
To preserve old messages, you can enable the archiving feature of VMware Aria Operations for Logs. See Data Archiving.
Data stored by VMware Aria Operations for Logs is immutable. After a log has been imported, it cannot be removed until it is automatically retired.
