Overwrite old log or audit entries when log storage is full

By default, Log Servers stop receiving log entries when the log storage is full, and Management Servers shut down when the audit storage is full. You can optionally overwrite old log entries when the log storage is full.

When you configure Log Servers or Management Servers to overwrite old log entries or audit entries when the log or audit storage is full, the Log Server or Management Server writes new log entries or audit entries over the existing entries, starting with the oldest entries, until more disk space is available.

For more details about the product and how to configure features, click Help or press F1.

Steps

Select Configuration, then browse to Network Elements.
Browse to Servers, right-click a Log Server or Management Server element, then select Properties.
Configure the option to overwrite old log or audit entries depending on the type of server.
- Log Server — From the Log Storage Full drop-down list, select Overwrite Oldest.
- Management Server — From the Audit Storage Full drop-down list, select Overwrite Oldest Audit Entries.
Click OK.
