Hello,
How to monitor "Average Bytes/Transfer" counter on Datastore or Disk?
ESXi 6 U2
Hi,
you need to change the collection level of your performance counters to 3.

Note that by doing that you will increase the size of the db and it can impact performances.
Level 3 is supposed to be for troubleshooting purpose.
It is in "vcenter server" > "manage" > "settings" > "General" > "Statistics"
Alternatively you can spin a VM and install VEEAM ONE. You will have 1 week of historical data which is pretty neat.
Cheers,
Currently i have Statistics Level=4 for 1 Days and Statistics Level=3 for 1 Week, but i do not see "Average Bytes/Transfer" counter
I'm not sure that what you are looking for is doable in the web client, here is a list of the performance counters.
By the way, when you say "Average Bytes/Transfer", are you looking for an average usage metric in kbps or an average IO size?
i need monitor counter like
"Avg. Disk Bytes/Transfer is the average number of bytes transferred to or from the disk during write or read operations."
You are looking for the average size of IO then.
The only ways I can think of to find that are:
- Per VM, Use vscsistats on each VMs on a datastore then do an average of that (never tried that)
Using vscsiStats for Storage Performance Analysis
- Use the monitoring of your storage array if it can give this metric
