I agree with @_Val_ . I always just run cpstat without any flags and it will show you all available options, for sure.
Here is what I see on R81.10 gateway:

Then I ran cpstat blades -f ips and got below:
cpstat blades -f ips
Invalid flavour 'ips' for product 'blades'. Use 'cpstat' without any arguments to see supported products and flavours.
Also tried what Val suggested cpstat -f ips blades, but same issue.
Its possible that certain flags dont work right, not sure.
