ESX host to vCenter network traffic

I'm somewhat new to VMWARE. I see a fair amount of network traffic from a remote ESX host to the vCenter server. Wondering what that might be. Important because the remote site with the host has a small network pipe and we're having performance issues.

How much bandwidth are we talking about exactly here?

There shouldn't be too much traffic between vCenter and ESXi hosts, it's mostly management traffic and ESXi sending periodic performance data of host and VM objects to vCenter. Depending on how many VMs run on that host and what your vCenter statistics collection level is, the amount of performance data being sent data can vary a lot:

Especially statistics level 3 and 4 will generate a lot of data and also bloat your vCenter database: Data Collection Levels

If you have VUM on vCenter as well then pushing patches can take up a lot of bandwidth, but I don't think you're doing that.

I know this is an old question, but did you ever get an answer?

Thanks,
