I know all of that. And I never said it was easy
But I SUPPOSE it could be accomplished for at least some parts. So I suppose it would be possible to display resource usage for each running script.
Yesterday night I tried to debug a fairly complex script, and the CPU on the system went to 90% quite often. I thought it was the script, but it turned out to be something else after a few hours.
If I could have seen the script isn't actually using much CPU, I could have saved some hours ripping out my hair (because there are _no_ debugging possibilities for scripts in RouterOS) and find the problem earlier...
But, after all, I suppose we just won't get such a feature, I fear.
