I found some problem in my system

I think this is just something that Apple is doing internally to track the prevalence of some internal bug. Then, when they collect all of the analytics from users who have opted-in to sharing analytics, they can decide whether this is something they want to bother looking at and/or what other factors are common to all other people experiencing it.

Probably the only significant aspect of this is the "226". That means there are at least 226 of these issues. At any given time, there are thousands of documented bugs in the operating system. Apple only ever fixes a tiny fraction of them. Unless you are experiencing some specific problem, there is nothing to worry about. Even if you are experiencing a specific problem, I can guarantee, with absolutely 100% certainty, that reviewing logs will be a waste of your time.

What problem did you find? Those screenshots don't indicate any particular problem.

There is no problem. That is the operating system's normal collection of statistics about system performance.

What makes you think you should think that just because you see a random string in a log you don't understand?

If you keep looking around, you will find much scarier sounding messages. Then you'll keep searching, finding more and more until you go crazy.

Unless your Mac is behaving poorly, you don't have a problem. Even if your Mac was working poorly, the logs would not provide you with any information from which you could determine a cause or a fix.
