Title: Alarm for very high Enhanced Datapath flow table usage.
Event ID: esx_health.enhanced_dp_flow_table_usage_very_high
Fixed in the release: 4.2.0
Alarm Description
Cause
If the number of active flows exceeds the flow-table size, or if there are many short-lived connections coming in, the flow tables can fill up. Increasing the flow table size is beneficial when the number of active flows is stable over time. However, this might not improve performance in cases where short-lived connections continuously come in. In such scenarios, the flow table might always be full, regardless of its size.
Note: This article is for very-high-usage (above 95% occupancy). For high-usage (90-95% occupancy), please refer to KB Article 345796
