Check on Wooden Porch Roof Post

There is a 10 inch by 10 inch solid wood post that supports a porch roof. There is a 0.5 to 3/4 inch check or Crack running the entire length up the post. There is no rot but it is a fairly recent build. Should I recommend filling the split (check) with caulking or epoxy just to prevent Rot? Or should I just tell them to monitor it? There are no worries about the integrity of the post.

There are no worries about the integrity of the post.

w/o pix
narrative depends on wood species
if the wood is rot resistant maybe ok for now
if not requires fill & paint/stain
i include a maintenance link for rot resistant so i don’t get the year or less call “why didn’t you tell me my pretty wood would turn gray”

no graycism here

Wood in the check should be treated with the same finish coating as the exterior of the post. Basically, the wood inside the check is just an extension of the wood on the outside of the post. I wouldn’t even recommend monitoring it.
If it were in a beam (oriented horizontally) and the check could hold water, I recommend filling of checks wider than ¼" with an appropriate material.
