Network
Let's recap what we need to produce in order to monitor network capacity:
- A line chart showing the maximum network dropped packets at the physical data center level. We use a physical data center and not vSphere cluster, as they eventually share the same core switches.
- A line chart showing the maximum and average ESXi vmnic at the same level as per the previous point. This will tell you whether any of your vmnics are saturated.
In the first line chart, notice it only has the maximum line. We're not tracking the average dropped packets. The reason is that we're not expecting any packet loss, so the average is irrelevant.
We covered the first line chart in the performance chapter. So we just need to add the utilization line chart.
Dropped packets are much easier to track, as you expect 0 everywhere. Utilization is harder. If your ESXi has mixed 10 GE and 1 GE vmnics, you would expect the 10 GE vmnic to dominate the data. This is where consistent design and standards matter...
