If you set it up as script, then your script should only output the data for one of the instances (app/service/process). In that case, the output should look like this according to the support documentation:
datapoint_name: value
So, in your case, it would look like this:
cpu: 87
However, if you chose batchscript (which you likely should change if you didn't), then our output should look like this:
instance1.key1: value1
instance1.key2: value2
instance1.key3: value3
instance2.key1: value1
instance2.key2: value2
instance2.key3: value3
So, in your case it would look like this:
sihost.cpu: 23
ssonsvr.cpu: 8
ShellExperienceHost.cpu: 20
SelfService.cpu: 9
SelfServicePlugin.cpu: 15
