VIP and POOL status using RestAPi

I don't know what technology or language you're using to make the calls, but getting all VIP status would use the following URL, using GETs: (use your own values for the $ variables obviously)

https://$ltmname/mgmt/tm/ltm/virtual?ver=12.1.1&expandSubcollections=true

For an individual VIP it it would look something like this:

https://$ltmname/mgmt/tm/ltm/virtual/~$ltmpartitionname~$ltmvipname?ver=12.1.1&expandSubcollections=true

Pool status would be similar but with "pool" instead of "virtual" in the URI.
