While designing a new network architecture, and even when we already managing it, there are several things that we should ask ourselves:
- What is my network usage for each virtual network type – vMotion, Management, iSCI etc…
- How can I know if the network load-balancing is working as i thought that it’s working?
For this purpose – I’ve tought of writing the following series of posts, which in the end of it – will enable the VI admin a better view of the current network performances and will help in the decisions you will take in future plannings.
In this example – I’ll use a configuration which is very common at customers – a dvSwitch with one VMkernel and two VMnics sets to “Active” attached to.
Let’s say that this dvSwitch is running our Management network, but this is just an example as you can also do this for other traffic types.
Host VMnic2 Management Network Usage in MB
sum(This Resource: net|vmnic2|usage_average)/1000
usage_average = Resources -> Hosts Systems -> Network -> vmnic2> Usage Rate (KBps)
Host VMnic3 Magement Network Usage in MB
Host Network Management Usage in MB
usage_average = Resources -> Hosts Systems -> Network -> vmnic2 -> Usage Rate (KBps)
usage_average = Resources -> Hosts Systems -> Network -> vmnic3 ->Usage Rate (KBps)
That’s all for the first part of the series.
In the next parts for this series we’ll proceed to build our ‘Host Network Health Status’.
