ESXTOP and Get-esxtop

[habs3]

Hi All

I am trying to use get-esxtop to gather numofdroppedsend and numofdroppedrecv stat and i am using

get-esxtop -countername netport | where {$_.clientname -eq "vm"} | select *

it returns the data but has a number of 1952 for numofdropedrecv

when i look at esxtop on the same server for the same vm it shows 0 for $drptx and %drprx

i was wondering why and if i am gathering the data from the wrong counter.

Any help would be great

Thanks

John

The values you get returned by Get-EsxTop are mostly cumulative, meaning you will have to calculate the delta between 2 consecutive measurements, to get the actual value for the past 5 second interval.

You find more info in my Hitchhiker’s Guide to Get-EsxTop – Part 1 post.

Thank you for the response. I was wondering. if I get a value back from Get-esxtop but none from esxtop on the host. Where is get-esxtop getting the data from and how long is that data there for?

We are having issues in our environment and I am looking to monitor dropped packets and log it so if the issues we are having pops up again I can see if there are dropped packets I will be able to send that data to our network team for analysis based on routes and what is see in the switch.

Thanks again.

In esxtop you see the deltas between 2 consecutive measurements, in Get-EsxTop you have to do delta calculation yourself.

Both use the same values to start with.

I created a function which will give you the deltas, see Hitchhiker’s Guide to Get-EsxTop – Part 2 – The wrapper
