I like that a lot. I'll try to spin-up a PR (MR on gitlab?) today.

Yes, this is a good idea. Simple extension of current code.
The command line would then be
-snes_converged_reason ::failed
add in petscviewer.h
a new PetscViewerFormat PETSC_VIEWER_FAILED,
add in viewera.c PetscViewerFormats FAILED.
add in SNESReasonView

The only slight annoyance with doing this through a PostSolve hook as
opposed to a pluggable ReasonView system is that if a user passed
`-snes_converged_reason` on the command line, we would get redundant
printout from SNESSolve and our PostSolve. Although I suppose we could
solve this by
KPSSetPostSolve(), There is no SNESSetPostSolve() but there could/should be.

Note inside the SNESSolve there are a bunch of pre and post hooks, don't get
the confused with an outside SNESSetPostSolve()

One alternative is to support a plugable KSP/SNESReasonView system. We then
could hook up KSP/SNESReasonView_MOOSE.
We could call our views from SNES/KSP"done"Solve as well if such a
system is not affordable. What are the final functions we should call,
where we guarantee SNES/KSP is already
Alex,
The actual printing is done with SNESReasonView() and KSPReasonView() I
would suggest copying those files to Moose with a name change and removing all
the code you don't want. Then you can call your versions immediately after
SNESSolve() and KSPSolve().

You can also do this with a monitor and get the converged reason to do what
you want:

To help debug the many emails we get about solves that fail to converge, in
MOOSE we recently appended `-snes_converged_reason -ksp_converged_reason`
for every call to `SNESSolve`. Of course, now we have users complaining
about the new text printed to their screens that they didn't have before.
