The cron job could craft the report and deliver it directly to the Xymon server using the xymon binary, if you're OK with root doing that.

Maybe a cron job running as root to do the stat and drop the results into a file in Xymon's tmp directory, where an ext script can read and report? The root script could read the list of files from the Xymon client's local.cfg.

As soon as I read this, I had my "D'oh!" moment. Of course, the "sudo find" only generates the list of files to check. So not a bug. A permissions error.
Anybody know of a way to give Xymon elevated access permissions when it stats files it's checking? I would prefer not to change the directory permissions if I can avoid it.
Thanks Vernon

OK, so you are using sudo to generate a list of filenames, so xymon can read the list of filenames you want to monitor (the same as if you just hardcoded /var/crash/bounds and /var/crash/vmdump.0 into the clientlocal.cfg file.
However, when xymon tries to look at the details for the file you have asked it to check, it can't determine *any* information about the file, not even whether it exists or not, because it doesn't have sufficient privileges. You would need xymon to have sudo power to check the file as well, (not sure if that would be feasible) or else to add at least rx permissions for xymon to be able to provide information:
ls -ld test drwx------ 2 root root 4096 May 23 09:10 test agoryachev at it-desktop:/tmp$ ls -l test ls: cannot open directory test: Permission denied agoryachev at it-desktop:/tmp$ sudo chmod +r test root at it-desktop:/tmp# exit agoryachev at it-desktop:/tmp$ ls -l test ls: cannot access test/two: Permission denied ls: cannot access test/one: Permission denied total 0 -????????? ? ? ? ? ? one -????????? ? ? ? ? ? two agoryachev at it-desktop:/tmp$ ls -l test/one ls: cannot access test/one: Permission denied agoryachev at it-desktop:/tmp$ sudo chmod +x test root at it-desktop:/tmp# exit agoryachev at it-desktop:/tmp$ ls -l test total 0 -rw-r--r-- 1 root root 0 May 23 09:10 one -rw-r--r-- 1 root root 0 May 23 09:10 two
So you can read the directory contents with +r, but you need +x to be able to stat those directory entries. At least, that applies on my Linux workstation, it may depend on your OS/etc.

Hi allNot sure if this really classifies as a bug or not. I am inclined to think it is.
In clientlocal.cfg, I have [sunos] file:
/usr/bin/sudo /usr/bin/find /var/crash/ -type f 2> /dev/nullAnd this finds 2 files. /var/crash/bounds /var/crash/vmdump.0 So far so good.
However, /var/crash/ is a symlink to /var/share/crash/ And /var/share/crash has permissions or 700 So Xymon can determine there is a file, but cannot collect any metadata on the file, since it cannot stat the files in /var/share/crash/
In analysis.cfg I have this line (with appropriate HOST= value, of course) FILE %^/var/cores/.* NOEXIST red When I go to the "files" page, I see the file names there. Clicking on the file names, I get this info. [file:/var/crash/vmdump.0] ERROR: Permission denied
But no red status appears on the test. Testing, using a similar directory structure, where Xymon can stat the files, does give a red status.
I can understand that Xymon can't give any info on the file because of permissions, but in this case, all I care about is that the file exists, which Xymon has determined. That should trigger a red status.
Using Xymon 4.3.10
