Fighter availability by type and nation

A shocking 50% of the Indian Air Force’s (IAF’s) Sukhoi-30 MKI fighter fleet is on the ground due to unresolved servicing issues with the aircraft’s Russian manufacturers.

I found this in another thread and wonder if we can list availability by type and nation,
i’d like to get an idea of effectiveness, if IAF had a fleet of less than half of them, but with 100% availability,
it would still provide more combat value, not to mention savings which again in the end provide more combat capacity
