By far, the easiest way to monitor the clone copy duration is the CLI method already supplied. It's automated and will report on all devices in the DG with a single response / return code. Next easiest is to look at the Unisphere performance data at the device level. Check the "BE reads for copy" metric OR with STP, the "DA reads for copy per sec" metric. You will get historical data using this method.
Inlines does not provide the historical data you are after. Realtime monitoring is required to keep track track of the protected tracks count.

Use the "verify" parameter of the symclone command to check that devices are in a particular state. The command will generate a non-zero return code if some or all of the devices are not in the state being verified... Useful for scripting.
for example, to check that a clone with precopy has completed the first pass, use command:
symclone -g clone_dg verify -precopy -cycled
To check a clone copy has actually copied all the data use "verify -copied"
This type of check needs to be done in real time, so the best way to keep a record of clone copy duration is to incorporate the verify into the clone script.
You can see when symclone control commands were issued via symaudit, but cannot know how long the copy took historically via the CLI or inlines. You may be able to get an idea of historical clone duration by looking at the performance data on the devices.

I'm happy to discuss inlines with you, however the customer community forum is not the appropriate place. Send me an email and we can take it from there or open a post on inside emc.
