What about license restrictions?
I heard Brent speak about this and my understanding was that you are not allowed to store the result of sp_Blitz or save the script on any server that you are comercially working on. I.e. on clients machines.
If I am correct you may only use this on servers that your employer own.
I hope I am wrong because I love the script. But today I would not put it on any of my clients servers because of this.
You'll have to ask Brent Ozar Unlimited about this. We own this server, so I think we're OK. If we're out of compliance, I'm happy to remove results.
We aren't really storing results, however. We're storing a count of issues. Then we compare that count and if it changes, we can run the script and look for something that stands out. Ideally I'd like to get this list down to 0, but that's not easy to do.
