Edge CPU usage high alarm

Issue/Introduction

Title: Edge CPU usage high
Event ID: edge_health.edge_cpu_usage_high

Alarm Description:

• Purpose: On an Edge half the CPU cores are assigned to datapath processes, and the other half are assigned to non-datapath service processes such as Load Balancing, GW FW etc ... For example a large Edge has 8 * vCPU's assigned to the VM, with cores 0 - 3 being assigned to the datapath and cores 4 - 7 to the services. This alarm is there to inform the user that the Edge CPU usage for non-datapath CPU cores has reached very high levels. 
• Impact: This alarm is a warning that the Edge may start to see performance related issues due to the high CPU load for services that run on non-datapath CPU cores.

Environment

VMware NSX-T Datacenter
VMware NSX

Recommendation Action:

• The user should review the configuration, running services and sizing of the Edge node. Consider adjusting the Edge appliance form factor size or rebalancing services to other Edge nodes for the applicable workload.
