Things can be difficult when you don’t know where a network issue may be.
In today’s datacentre, the rapid need to deploy business applications in minutes is necessary to keep the business ahead of the game. It is even more crucial to keep security and rapid networking configuration in control. So, how can a network administrator get to the bottom of a network issue in a matter of seconds in this new cloud era?
Network Virtualization brings operational and management flexibility and simplicity, but adds a complexity to troubleshooting and pinpointing the root cause of a network issue.
The traditional way would be to check the network activity from vCenter on the ESX level on the physical nic card, and check the packet going on as you run the test. It is also necessary to check the physical network activities and compare with the virtual network traffic and deduce where the bottleneck is.
If now you need to cross check between VCs and multiple sites, how long will it take to figure out the configuration issue? The required information can be gathered on one search on vRealize Network Insight.
