Try this: chronyc -m sources sourcestats This will print the sources and then the source stats. I suspect that the other sources you have are not actually being polled or are not reachable. Check the “Reach” column in sources. Denny > On Jun 3, 2023, at 14:31, Torsten Wolf <[email protected]> wrote: > > Bryan, many thanks for the explanation and the suggestion regarding SHM0.
