Fw: ===NRPE: Unable to read output

[Pavleck, Jeremy D.]

We'll also forward this to the list. Sorry for top posting, Blackberry and all.

And what do you get for check_nrpe --version?
I'm not positive right now, but I believe if you use an older check_nrpe with a newer nrpe (or vice versa) it won't work, something about the ssl-enabled nrpe and the older check not expecting it.
Also try turning on debug in your nrpe.cfg and running a few checks, then looking at the output in the log. Also, I'm not absolutely positive, but I believe there's a check_nrpe --verbose, which may show more of what is returned.

Oh, and search the docs for that error, should be more info there.

Usually with (No Output) errors it tends to be permissions, paths, or commands.

Hi Jeremy,

From the client:

[nagios at 83556-dev etc]$ /usr/local/nagios/libexec/check_procs -w 150 -c 200
PROCS OK: 125 processes
[nagios at 83556-dev etc]$ pwd
/usr/local/nagios/etc
[nagios at 83556-dev etc]$ ls
backup  nrpe.cfg  nrpe.cfg.orig

from the nagios host:

	Hi Folks,
	
	I am setting up Nagios with my first client. This is the output
	I get when I execute the
	command from the command line from the Nagios host is
	
	"NRPE: Unable to read output "
	
	It also shows up in the nagios.log.
	
	The command line exec is:
	
	./check_nrpe -H 83556-dev.slc.com -c check_total_procs
	
	I have nrpe running on the client:
	
	nagios 25998 1 0 Apr10 ? 00:00:05
	/usr/local/nagios/libexec/nrpe -c /usr/local/nagios/nrpe.cfg -d
	
	I am running xinetd and the service definitions on the client
	are in /usr/local/nagios/etc/nrpe.cfg:
	
	command[check_users]=/usr/local/nagios/libexec/check_users -w 5
	-c 10
	command[check_load]=/usr/local/nagios/libexec/check_load -w
	15,10,5 -c 30,25,20
	command[check_disk1]=/usr/local/nagios/libexec/check_disk -w 20
	-c 10 -p /dev/hda3
	command[check_disk2]=/usr/local/nagios/libexec/check_disk -w 20
	-c 10 -p /dev/hda2
	
	command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5
	-c 10 -s Z
	command[check_total_procs]=/usr/local/nagios/libexec/check_procs
	-w 150 -c 200
	
	Why am I getting this error?
	
	Thanks, --Joe McCaughan
	
	
	
	Joe, 
	This might be a dumb question, but does the directory
	/usr/local/nagios/libexec/ exist on the client (83556-dev.slc.com)? 
	Can you run /usr/local/nagios/libexec/check_procs -w 150 -c 200 as the
	NAGIOS user and see a return?
	What version nrpe & check_nrpe? 
	
	Using Tomcat but need to do more? Need to support web services, security?
