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 all
Not 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/null`
And 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

Vernon
