Definitely read-only on group perms on the master here - it would be useful if you can confirm that read-only on group works for you too.

If anything, it's why the httpd needs any permissions to the smokeping var data in the first place that puzzles me.

...it appears that the httpd is only acting as an intermediary between the slaves and master (with the master handling all file IO) and it shouldn't need to read or write any of smokeping's var data, so it's not that the httpd only needs read perms that I find a bit strange but that the httpd needs any perms to the smokeping var data at all for slaves to work.

Still an extremely useful bit of software though.
