It doesn't look healthy to me. The Post-RS errors (packet loss on the downstream) are a worry unless they are historic and not rising.

Also, the DS power levels are askew. Although the values are nowhere near out od correct range, the lower frequencies should require less power than the higher frequencies - and that's not what happens in your case. Either the cabinet amplifier is faulty or incorrectly sloped (you can Google that!).
