Circular path...

[Rafael F Suguiura]

Mike,

Thanks the explanation. I got it...
But at least I want to remove those serials from map, because they appear
directly connected to the nagios process, what is not the true...
I´m attaching a screenshot of my map, with some annotations.
It is possible?

Thanks again,
Rafael.
