Network Monitoring Enhancements in vSAN 7 Update 2

Network Monitoring Enhancements in vSAN 7 Update 2

Administrators need to be able to quickly understand the health and performance of a network. Visibility into the network is key to a reliable and consistent hyperconverged platform. VMware vSAN 7 Update 2 introduces several new metrics and health checks to provide better visibility into the switch fabric that connects the vSAN hosts.

Several new metrics are included to monitor the physical networking layer, including CRC and carrier errors, transmit and receive errors, and pauses.  Visibility is added at the TCP/IP layers including ARP drops and TCP zero frames. Information on what these metrics mean can be found at VMWare KB2144493.

Not only do these metrics show up in time-based performance graphs, but new health alarms have been added to ensure an administrator knows they are approaching or surpassing critical thresholds. All of these new network metrics and alarms will augment the existing collection of networking metrics already found in vSAN to give administers better insight into the health and well-being of their network. 

Alarm dashboards can be exported for further review.
