so, this works as expected:
`dimensions= { 'Name':'InstanceId', 'Value':instance.id }`

when adding more values, only the last one gets applied:
`dimensions= { 'Name':'InstanceId', 'Value':instance.id,`
                      `'Name':'Filesystem', 'Value':'/dev/root',`
                      `'Name':'MountPath', 'Value':'/',`

Got this fixed...  The python dict format should be `{ 'InstanceId' : instance.id }` without the name/value tags.  Not sure why it worked with them.  If anyone else comes across this issue:
        `dimensions= { 'InstanceId' : instance.id,`
                                  `'Filesystem' : '/dev/root',`
                                  `'MountPath' : '/',`
        `}`
