How to get the value of multiple pv quantities over a period of time at the same time

slacmshankar commented 5 years ago

You can use something like so curl -s "http://archapp/retrieval/data/getDataForPVs.json?pv=pv1&pv=pv2".

Not all mime types are supported but you should be able to get .json, .raw etc
