Well that depends on what vision you have for the "aliens"...
If there is a civilization that is superior to us and capable of monitoring things like you propose (think about the distances and time of relaying
the intel) it would be an extremely wasteful proposition.
We can even extrapolate looking to our own future Not the one in the path we are now, but the one that would be logical that we would be pursuing.
Life expands it colonizes, we should already be out of this rock and spreading (like a virus
) for at least half a century (the strange thing is
that we aren't and have only half-baked plans to do so, most if not all being only pipe dreams that have no stand in reality, even China's proposal
of a moon colony seems now to be dim). In any way if we extrapolated from what would "normally" occur is expansion from a planet based civilization
to a solar civilization and so forth. (There are alternatives and shortcuts but as I said it depends on what type of alien we are talking about).
If we establish this a the normal path of evolution for a civilization that has universal ambitions, that includes the need you mention to monitor
other contenders, the best path is to create or pollinate life itself and take control of the process, this reduces the need to monitor for it in the
first place, to play a game of chance, if you create and manage life spread and evolution you can save yourself a lot of trouble.
In any case the dumbest thing to do is to announce other contenders of your own presence, like we did with voyager or with radio signals, there is a
multitude of possibilities that would make our presence known a vary bad idea, even if the aliens would be well intentioned. The creation of
monitoring stations would fit right in that category, not to mention that the work it would take and the technology that would permit it could do the
seeding of life itself in every crack that would hold it.
