When looking at Virtual Machine Health ( Environment Overview -> Getting Started TAB ) how does Foglight determine what VMs have low performance?
This data is taken from Change Analyzer VM performance dashboard (VMware Environment/Change Analyzer/VM Performance).
The Change Analyzer creates a derived metric using the following constraints:
CPU_READY, CPU_UTILIZATION, SWAPPED_MEMORY, ACTIVE_MEMORY, BALLOON_MEMORY, ALLOCATED_MEMORY, RESERVATION_MEMORY
You should be able to identify if few of them are problematic.
To further investigate, please find the doc attached with screenshots.
