Actually I did ran commands under root, until you've advised to su to
Nagios user (completely forgot about it!).
 
Now I did all the checks logged as Nagios users, and I have same results
- where it's working - it's working, others still don't.
 
Could it be somehow related to ssh or probably NIS configuration (since
I do have Nagios user created in NIS)?
 
How does check_disk plugin work? Does it use "df" cmd or somewhat else?

Yours faithfully,

I have read your original post again. It says:
>>>
When I'm trying to check some of the plugins locally (i.e.
/usr/local/nagios/libexec/check_disk -w 10% -c 5% -p /) it's working
fine, without errors.

<solaris9_box>> /usr/local/nagios/libexec/check_disk -w 10% -c 5% -p / 
DISK OK - free space: / 851 MB (21% inode=86%);|
/=3138MB;3627;3829;0;4031 

<<<

But now you say it doesn't work locally:

>>>

On nagios-non-working box:
su - nagios
/usr/local/nagios/libexec/check_disk  -w  20%  -c  10%  -p  /
DISK CRITICAL: / not found
 
<<<
 
This indicated a problem in the nrpe communications. 
Now you say the problem is seen executing the plugin locally.
 
Also, when you use the -v option on check_disk, you had better be
specifying the -w -c and -p options too!

	OK, you do have a point in your words :)
	 
	Now, what results I've got:
	On nagios-working Sol9 box:
	su - nagios
	/usr/local/nagios/libexec/check_disk  -w  20%  -c  10%  -p  /
	DISK OK - free space: / 7560 MB (75% inode=95%);|
/=2419MB;8064;9072;0;10080
	 
	On nagios-non-working box:
	su - nagios
	
	/usr/local/nagios/libexec/check_disk  -w  20%  -c  10%  -p  /
	DISK CRITICAL: / not found
	 
	Now, what exactly is the point here?
	If I'm trying to invoke [/usr/local/nagios/libexec/check_disk
-v] it goes with: DISK UNKNOWN - free space:|

	OK, so this may be still an error in the nrpe.cfg.
	What is the configuration line in your nrpe.cfg on the
<Solaris9_box>?
	For example:
	command[check_disk]=/usr/local/nagios/libexec/check_disk  -w
20%  -c  10%  -p  /
	 
	Try to cut and paste everything after the equals sign and
execute it on the <solaris9_box> as user nagios. This verifies that all
the parameters to the plugin are being supplied correctly.
	Remember that any changes to nrpe.cfg requires a restart of the
nrpe daemon.

		Hi!
		 
		Thanks for reply.
		I did all the checks from Nagios server and when I'm
invoking this command:
		 
		/usr/local/nagios/libexec/check_nrpe -H <solaris9_box>
-c check_disk (check_disk in this example is the check of the root
slice)
		 
		I'm receiving this:
		DISK CRITICAL: / not found
		 
		I already got 2 Solaris9 boxes with such an error, while
others are ok.

		Yours faithfully,

		If it works correctly on the monitored system
(solaris9_box), then the next thing to verify is from the command line
on the Nagios server (I assume you are not passing any parameters via
check_nrpe) viz:
		 
		<nagios-svr> /usr/local/nagios/libexec/check_nrpe -H
<solaris9_box> -c check_disk
		 
		This will verify that:
		1) the communications are okay (probably in your case
since other checks work), and
		2) the nrpe.cfg is correct on the monitored system
(solaris9_box).

			Hi 2 All! 

			I got one question regarding check_disk plugin,
it's work actually. 

			I have Solaris 9 box (SPARC) with compiled
plugins (1.4.13) and NRPE daemon (2.12), done with SSL support.
Monitoring host is RHEL4, working fine.

			When I'm trying to check some of the plugins
locally (i.e. /usr/local/nagios/libexec/check_disk -w 10% -c 5% -p /)
it's working fine, without errors.

			<solaris9_box>>
/usr/local/nagios/libexec/check_disk -w 10% -c 5% -p / 
			DISK OK - free space: / 851 MB (21% inode=86%);|
/=3138MB;3627;3829;0;4031 

			But when I'm doing it through monitoring host
(via Nagios configuration) - it goes with "DISK CRITICAL: / not found". 
			While all others plugins - such as "CPU Load",
"Current Users", "HTTP check" - are working OK. 
			It's not SSL shaking error, because I did all
the checks, and other plugins working OK. But when I'm trying to check
disk space - all faulty.

			PS. I have a few other Solaris boxes (v9), with
the same versions of plugins and NRPE, compiled the same way. And all
working OK on them regardin disk space usage.

			Yours faithfully,
