I don't know about this particular case, but direct and clear can be read more like "accusing" depending on your culture. I think this reads more like "hey is everything okay?" than "why are your numbers dipping?"
Definitely - personally I feel the opposite. The more indirect, the more offensive it reads. “Is everything ok?” tells me there is a problem I need to expose myself (am I underperforming? Do I look unwell? Did I say something wrong?). Feels like a trap.
I’d rather hear what the problem is and how they think it can be fixed. (EU based)
