Logs

In the VMware GemFire® Management Console™, the Logs tab allows users to view log files for locators and servers on connected clusters. Use the Logs tab to:

• Search logs

• Filter logs by log level and date range

• View multiple logs side-by-side for comparison purposes

Note: The Logs tab is intended for use in development processes, and may be insufficient for trailing production systems experiencing real-life traffic volume.
