Ethereal-users: Re: [Ethereal-users] IO Graphs - Advanced Y axis unit option - load(*)
No LOAD will not do that.
LOAD takes as parameter a relative time field and will calculate the
queue-depth for those commands.
LOAD is intended to take a relative time field, such as the response
time fields present in many of the protocols that can match requests
with responses (NFS/ iSCSI/ SMB/ ...)
Then LOAD will calculate the average queue depth for that protocol and
plot it over time.
You can then monitor the relationship between a client and a server by
studying how the queue-depth changes over time.
A command spanning the entire tick interval is displayed as 1000 (to
be able to use integer arithmetics and still have reasonalbe accuracy)
If a command spanned on average 50% of the tick itnerval it will be
displayed as 500
If there were three commands in parrallell that spanned the entire
interval it will be displayed as 3000.
