Micro Flow Cache hit rate on Edge node vmwNsxTDataCenterEntityId has decreased below the specified threshold of vmwNsxTDataCenterFlowCacheThreshold% for core vmwNsxTDataCenterCoreId, and the Datapath CPU usage has increased for the last 30 minutes. Action required: The Cache Flow hit rate has decreased for the last 30 minutes which is an indication that there may be degradation on Edge performance. The traffic will continue to be forwarded and you may not experience any issues. Check the datapath CPU utilization for Edge vmwNsxTDataCenterEntityId core vmwNsxTDataCenterCoreId if it is high for the last 30 minutes. The Edge will have low flow-cache hit rate when there are continuously new flows getting created because the first packet of any new flow will be used to setup to flow-cache for fast path processing. You may want to increase your Edge appliance size or increase the number of Edge nodes used for Active/Active Gateways.
