Viewing the TLB Service Details

 

Monitoring TLB is to view all the TLB-related health and status. For example, assume that operator is seeing the SDG is marked red and upon further investigation by using the SDG Monitoring page, it is detected that greater than 30% of the real servers are down, based on this criteria, the TLB is marked as red. The operator selects the particular SDG and drills down to view the service details.

When you select an SDG pair on the left pane of the Monitoring page, you can drill down to select a specific service instance or template of a particular type. You can expand the TLB tree to view the configured TLB instances.
