VMware NSX 4.1.x
On NSX Manager nodes sized MEDIUM, the maximum supported number of services objects is 2,500. This alarm is triggered when the number of service objects exceeds this limit.
To accommodate a higher number of services, consider resizing the NSX Manager nodes to a LARGE size, which supports up to 8,000 services instead of 2,500. This is referenced in the NSX Configuration Maximums documentation.
Follow the resizing steps and options outlined here: Resize an NSX Manager Node.
This alarm will automatically clear once the number of objects of the specified type decreases below the defined threshold.
