Write IO size for datastore using derived metrics

petrisor_grigore

I need help to calculate Total latency for datastores with below formula.

latency/ceil(IO size/32KB))

Is there a way to calculate write IO size for datastore using derived metrics? I see this metric is not available at the moment in vFoglight.

Thanks.

    Hi Gaston,


    In my case first option should be better because we are not managing OS layer ( Once high latency has been detected for the datastore, the rule will have to check if the Virtual Machines in that datastore are issuing large block sizes.)


    Thank you.
