[Nagios-users] nrpe errors when too many hosts
hi, We have nagios server that is working for long time. We note recently when we add new hosts, all NRPE checks fail with: Return code of 127 is out of bounds - plugin may be missing However, the plugin is there and we know it run fine from command line. Only when some new hosts added this happens. When you take new hosts out, errors go away. We don't have too many hosts in our file, only about 250. This problem is identical to the one find here: http://readlist.com/lists/lists.sourceforge.net/nagios-users/5/29272.html Alex -- This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
Re: [Nagios-users] nrpe errors when too many hosts
The error itself just means that Nagios can't find the plugin that you've told it to use. Every time I've ever encountered this error it boils down to something very simple; normally a typo or a mis-pasted file path. When you added the hosts did you also add the service, or were you using a service that has already been defined and used previously? Too, did you make any changes to your check definitions at all?

Re: [Nagios-users] nrpe errors when too many hosts
Do you have servicegroups defined? How many services does it show in the largest service group?

Re: [Nagios-users] NRPE: Unable to read output; but works when run under strace ...
I would try to run a basic script which logs the nrpe environment into a
file.
it will make sure what is available to you and what not.
test if:
there are environment vars..
there is a STDOUT\IN\ERR available etc..
#!/usr/bin/env ruby
f = File.open(/tmp/nrpetest.log,a)
f.sync = true
f.puts ENVIROMENTAR VARS\n===
ENV.each {|k,p| f.puts #{k} = #{p}}
f.puts STD DATA\n==
f.puts stdout exists?: #{$stdout}
if $stdout
f.puts stdout is tty?: #{$stdout.isatty}
begin
$stdout.write_nonblock 0
f.puts Wrote 0 to stdout
rescue = e
f.puts didnt wrote to stdout
f.puts e.message
f.puts e.backtrace.inspect
end
end
modify the above to make sure what is the cause of this problem.
you can also try to access stdout\err
Regards,
Eliezer

really a solution, but it'll do.

[Nagios-users] NRPE: Unable to read output; but works when run under strace ...
Hello all, given a fairly well-running monitoring setup with about 18k services I thought I had understood the basics. However, the following leaves me clueless, and I hope I'm merely missing something obvious here: On an up-to-date Debian Squeeze (i386) OpenVZ guest I have established that my monitoring user can execute a given command: root@vserv08:/# sudo -u monitor -i /usr/lib/nagios/plugins/check_dummy 0 success; echo Exitcode: $? OK: success Exitcode: 0 So far, so good.

Re: [Nagios-users] nrpe on ssl
Vishesh, The current default for NRPE is to use SSL. Additionally, you can specify allowed_hosts and the NRPE will only accept connection from the allowed hosts.

[Nagios-users] NRPE allowed_hosts directive
Hello, I am using NRPE version 2.7 and want to configured the allowed_hosts directive so that it can take a network address in the form network_address/netmask. However, it doesn't seem to support this, so I tried putting the IP addresses of all the hosts in the network. However, when I assign this variable to all the IP addresses (which is very long), I get this error: Feb 29 10:49:30 cn004 nrpe[22540]: No variable value specified in config file '/etc/nagios/nrpe.cfg' - Line 65 Feb 29 10:49:30 cn004 nrpe[22540]: Config file '/etc/nagios/nrpe.cfg' contained errors, aborting... When I truncate a number of IP addresses, it works fine. Do you know if the newer version of NRPE resolves this issue? Namely, can it accept network addresses (network_address/netmask) and/or take a long list of IP addresses? The former will be more convenient.

Re: [Nagios-users] NRPE/NSClient++ CheckCPU Error?
In the NSClient++ documentation, CheckCPU works with normal integers as thresholds (so no %-sign required). As an alternative, you can also check the CPU Utilization with the NSClientListener/check_nt plugin: http://nsclient.org/nscp/wiki/NSClientListener I use this way of checking the cpu loads/percentages for several hundreds of Windows servers and it works just fine.

[Nagios-users] nrpe, xinetd and LDAP problem
Hi: I have been trying to track down the fix for this for a while. We have a Nagios server monitoring a few dozen servers. Most of these servers authenticate users against a separate (CentOS Directory Server). We ONLY use LDAP for user/group authentication. It was configured via authconfig and even has a backup LDAP server. Whenever there is a problem with the primary LDAP server, all of the NRPE clients timeout on their services. Note that the nagios user and group exists in the local auth files on all these servers...there is no need for NRPE or xinetd to use LDAP: Aug 2 12:03:18 client1 xinetd[32012]: nss_ldap: failed to bind to LDAP server ldap://ldap1.domain.com/: Can't contact LDAP server Aug 2 12:03:18 client1 xinetd[32012]: nss_ldap: reconnected to LDAP server ldap://ldap2.domain.com/ Aug 2 12:03:18 client1 nrpe[32012]: Error: Could not complete SSL handshake. 5 The message then repeats in the log several times and we all get paged (texted) hundreds of times :-( I looked around and found that others have had this issue, but I don't see a fix. Is it an xinetd problem? Should we run nrpe standalone?

Has any one run into this issue and how to resolve? I come across this sort of thing more so with Unix test servers than Windows. I expect the easiest way to resolve this would be to configure NSClient++ to run the checks and send the results to Nagios using nsca. That way the agent will run them in its own sweet time and if they are rather slow it shouldn't matter too much. Alternatively you might be able to reduce the number of notifications you get by setting up a servicedependency so all of the checks are dependent on just one of them. If the alerts are Unknown rather than Warning or Critical then you can probably filter out the notifications using the notification_options directive either on the service definition or even on the contact definition. As ever, there are lots of different ways to approach the same problem! I hope that helps a little. -- 10 Tips for Better Web Security Learn 10 ways to better secure your business today.

[Nagios-users] NRPE and include_dir
Apologies if this list isn't appropriate for this question, but I thought I'd try here first. We're trying to use the include_dir directive in NRPE with an /etc/nagios/nrpe.d/ directory. My assumption was that files in this directory would be loaded in alphanumeric order, but it seems to only load in alphabetical order, ignoring numerals. For instance, if I have these files: /etc/nagios/nrpe.d/000-fileone.cfg /etc/nagios/nrpe.d/100-filetwo.cfg and they both define the same command, I would expect the one in 100-filetwo.cfg to take precedence, as it should be loaded second. However, this is not the case. (I've verified the order they are loaded with debug=1). If I have these files, though: /etc/nagios/nrpe.d/aaa-fileone.cfg /etc/nagios/nrpe.d/bbb-filetwo.cfg then things work in the order I expect (checks defined in bbb-filetwo.cfg will override checks defined in aaa-fileone.cfg). I'm using NRPE 2.5.2, which I realize is slightly old (2.12 seems to be the most recent version). I can't find a bug report for this issue, though, so I'm not sure if it's been recognized as such, nor if it's been corrected in newer versions. In fact, I see no documentation anywhere that specifies the order in which files will be loaded from within a directory that's been included with include_dir. Has anybody seen this behavior? Am I correct in believing it to be a bug?

Hi guys,
I hope someone can help me.
I'm trying to set up Nagios to return a warning for all red error logs in
both the system and application logs on a windows 2003 server.
So far no matter what I try I always get 'Eventlog Check ok' even when I know
that there are some red error's showing in the log.
I've just been running this from the libexec folder so far as I what to get
the syntax right before defining the service and alike.
./check_nrpe -H IP -p 5667 -c checkEventLog file=application file=system
filter-eventType==error filter-generated=\1d
Any ideas anyone?
NSclient 3.3.20 installed on windows machine.
If it's any help to you, the entry I have in my nsc.ini file in the
[External Alias] section is:
alias_CheckEventLog=CheckEventLog file=application file=system
MaxWarn=1 MaxCrit=1 filter=generated gt -1h AND severity NOT IN
('success', 'informational') truncate=800 unique descriptions
syntax=%severity%: %source%: %message% (%count%)
(that's all one line in case your email file wraps it)
As you can see it uses the new syntax. Note that to use external
aliases like this, you need to uncomment the line which reads:
CheckExternalScripts.dll
And you can query it from the Nagios server simply with
./check_nrpe -H IP -p 5667 -c alias_CheckEventLog
This method where all the command line options are in the agent config
can be useful for troubleshooting, as you're less likely to hit
problems with escaping non-alphanumeric characters. Once you have it
working nicely you can try moving to the the method you were trying
where the command line options are specified in the Nagios config.
I hope that helps rather than confuses!
Cheers,
Jim

Re: [Nagios-users] nrpe CheckEventLog
Thanks for the reply.
I fear the main problem here is the lack of knowledge that's sat in-between
my chair and my pc :)
I've edited the ini file on the server to allow both arguments and nasty
chars and restarted the service.
If I use the -a switch after -c checkEventLog all I get back is 'CHECK_NRPE:
Received 0 bytes from daemon... blah, blah blah...'
To me, that's suggests something isn't right on my windows server end, but
what?
As far as NSC config file on windows server 2003 is concerned I have :
;# COMMAND ARGUMENT PROCESSING
; This option determines whether or not the NRPE daemon will allow
clients to specify arguments to commands that are executed.
allow_arguments=1
;
;# COMMAND ALLOW NASTY META CHARS
; This option determines whether or not the NRPE daemon will allow
clients to specify nasty (as in |`'\[]{}) characters in arguments.
allow_nasty_meta_chars=1
For the rest this, probably, only, means that there is a syntax
conflict pending. Trial and error should lead to pinpointing the
problem
Als remember the versioning issue.

[Nagios-users] NRPE- Log files in syslog
Hi All: I use the NPRE plugin for Nagios and i know that setting the value of the variable debug to 1 in the nrpe.cfg file would make the debug messages to be logged into the syslog facility. Is there a way for me to make it log into some other folder of my choice instead of it even getting stored in syslog? I couldn't find the exact script/file where it actually writes stuff into syslog. It would be great if someone could tell me where to find this file or how to change the option to make it log into a folder of my choice. Also, i tried to find if i could find some plugin to log into some other folder. I could find many plugins for NSCA log but i couldn't find anything for NRPE. It would be great if anybody could help me with this. Thanks. Regards, Archana -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!

[Nagios-users] NRPE- Log files in syslog
Thank you Jeffrey. I'm actually new to both Nagios and the world of Unix. I shall however read up on syslog. I was very particular about this because i wanted to know the exact point where nrpe writes to syslog so that i re-route it and make it write to a place of my choice. The main reason I would want to do this is because i will not have access to the syslog of many servers in my company. On Wed, Jan 26, 2011 at 6:14 PM, Jeffrey Watts jeffrey.w.wa...@gmail.comwrote: You really ought to read up on syslog and how it works. It can do everything you're asking. The whole point of the syslog service is to abstract logging from the application - so that it can be centralized, filtered, separated, etc. :) Try (depends on which syslog you have running, ps can help you figure that out): man 5 syslog.conf man 5 syslog-ng.conf That will help you with the format of the configuration file. If you're not familiar with the concepts of syslog in general, I'd recommend googling. Good luck! Jeffrey.

Re: [Nagios-users] NRPE and ip range in allowed hosts
Hi So there is no way to specify a range of servers , one must put all IP's individually ? just as an idea: Can inetd handle the range of IPs?

[Nagios-users] nrpe check times out on one host, works perfectly on another.
Hello,
I have got a peculiar issue with nagios that I have been trying to
track down. I have an nrpe check configured to run a perl script on a
pair of firewalls (fwiw, it monitors the state table utilization for
pf). Nagios has no problems checking this script on the first
firewall, but it always times out on the check for the second
firewall. The firewalls are configured [nearly] identically, and if I
run the check_nrpe2 command manually on the nagios host (both as root
and as the nagios user), both hosts respond as expected.
nag...@calvin:~- /usr/local/libexec/nagios/check_nrpe2 -H
foobar-1-dev.claimlynx.com -c check_pf_states
2187 (%1.0935)
nag...@calvin:~- /usr/local/libexec/nagios/check_nrpe2 -H
foobar-2-dev.claimlynx.com -c check_pf_states
2383 (%1.1915)
I have restarted nagios and nrpe2 numerous times, with no effect.
Running nrpe with debugging enabled on foobar-2 (the problem host)
never shows any connections from the nagios host for the
check_pf_states check. However, other nrpe checks on this host are
working without any issue. I have also confirmed with tcpdump that
there are no uncompleted connection attempts, or any that request this
check.
The relevant parts of my nagios config are as follows:
define service{
host_name foobar-1, foobar-2
service_description Check pf State tables
use generic-service
check_command rcheck_pf_states
contact_groups clx-admins-email-24x7
}
define command{
command_namercheck_pf_states
command_line$USER1$/check_nrpe2 -H
$HOSTNAME$ -c check_pf_states
}
define host {
host_name foobar-1
alias Firewall Primary (Dev Interface)
address foobar-1-dev.claimlynx.com
use new-generic-host
parents sw-dev
}
define host {
host_name foobar-2
alias Firewall Secondary (Dev Interface)
address foobar-2-dev.claimlynx.com
use new-generic-host
parents sw-dev
}
The nrpe2 command definition is as follows. It is worth noting that
both firewalls read a shared nrpe config file (to prevent fat fingers
from getting in the way).
command[check_pf_states]=sudo /usr/local/libexec/nagios/check_pf_states
Here is my check script (try not to laugh too hard):
#!/usr/local/bin/perl
# This script checks the number of firewall states currently in use by pf
# and triggers an alert if the number of values exceeds a certain percentage
# of the maximum allowed states.

[Nagios-users] NRPE check_procs cutting off arguments?
We are using Nagios 3.0.5 and one of our services monitors a
particular job on a particular server:
define service{
...
check_command check_nrpe!check_myown1_job
}
and in the nrpe.cfg file we define that command:
command[check_myown1_job]=/usr/lib/nagios/plugins/check_procs -c 1:1
-a /home/myuser01/src/server/scripts/sync_api/
make_async_xmlrequest_libraries.py
We just upgraded NRPE and this check started failing - it reported 0
processes. However, the process was running and the command works
fine when run locally on the target machine.
After some trial and error, I discovered that the arguments to the
target process seem to be cut off.
This works:
command[check_myown1_job]=/usr/lib/nagios/plugins/check_procs -c 1:1
-a /home/myuser01/src/server/scripts/sync_api/make_as
but this fails:
command[check_myown1_job]=/usr/lib/nagios/plugins/check_procs -c 1:1
-a /home/myuser01/src/server/scripts/sync_api/make_asy
The commands are identical except that the second one has one
additional character ('y'). Any command longer than the first one
fails.
This also works:
command[check_myown1_job]=/usr/lib/nagios/plugins/check_procs -c 1:1
-a make_as
but this also fails:
command[check_myown1_job]=/usr/lib/nagios/plugins/check_procs -c 1:1
-a make_asy
So, it does not seem to be a problem in the argument string passed
in, but rather in the arguments read from the remote machine.
Is there some setting that controls size of the argument on the
target machine that will allow me to specify the entire argument?

[Nagios-users] NRPE: No output returned from plugin error
Hi all, I have this weird trouble with getting nrpe agents work. My nagios server hosts on Debian box while agents on Debian and Centos (all installed from official binary packages) and the problem is check_nrpe always returns this NRPE: No output returned from plugin error when I check NRPE on any Centos host and this is true with all plugins - all of them does not return anything. I turned on debug at one Centos host but still it does not show me anything, when I run from nagios host: ./check_nrpe -H centos.host.com -c check_load I always get NRPE: Unable to read output and there is nothing in syslog at agent's host in spite of debug is on. My assumption was that command definitions on Centos host side use path to plugins that is different from Debian, for example: command[check_load]=/usr/lib/nagios/plugins/check_load -w 15,10,5 -c 30,25,20 [Debian host] command[check_load]=/usr/lib64/nagios/plugins/check_load -w 15,10,5 -c 30,25,20 [Centos host] but I made symbolic link so that plugins could be called by the same path - it didn't help. When I run command locally, all works just fine: su nrpe -c /usr/lib/nagios/plugins/check_load -w 15,10,5 -c 30,25,20 OK - load average: 1.28, 0.97, 0.97|load1=1.280;15.000;30.000;0; load5=0.970;10.000;25.000;0; load15=0.970;5.000;20.000;0; while from nagios server: ./check_nrpe -H centos.host.com -c check_load NRPE: Unable to read output The weird part of it is that all plugins work fine on debian hosts. Nagios uses the same host, service and command definitions for all monitored hosts (both debian and centos) and I really wonder what's wrong with centos nrpe agents :/ If anyone have any ideas, please try to help.

Re: [Nagios-users] NRPE: No output returned from plugin error
Yuris,
You could try compiling nrpe without ssl and then in your commands.cfg file
have something like this;
*# 'check_nrpe' command definition
define command{
command_namecheck_nrpe_no_ssl
command_line$USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -n
}
*
Then in your specific service definitions have the check_command line read;
*check_command check_nrpe_no_ssl!put-whatever-plugin*
Hope this helps.

Re: [Nagios-users] NRPE: No output returned from plugin error
This is what I did. Some of my servers have nrpe compiled with SSL and some
without so I just created two commands in commands.cfg for it -- one to check
with NRPE with SSL and one without.

Re: [Nagios-users] NRPE: No output returned from plugin error
I had a very similar problem with checks coming from Ubuntu 8.04 and
10.04 destined for RHEL. I had to disable SSL on both ends and set
the encryption method to 0.
I would also check the NRPE config to make sure the passphrases match
if you are using them.

Re: [Nagios-users] NRPE: No output returned from plugin error
I strongly doubt it has any relation to ssl:
NRPE - Nagios Remote Plugin Executor
Copyright (c) 1999-2008 Ethan Galstad (nag...@nagios.org)
Version: 2.12
Last Modified: 03-10-2008
License: GPL v2 with exemptions (-l for more info)
SSL/TLS Available: Anonymous DH Mode, OpenSSL 0.9.6 or higher required
TCP Wrappers Available
this is output from nrpe (Centos binary package) that shows it's
compiled with ssl/tls support. Openssl library is installed as well.
Anyway. I tried suggested workaround, defining check_nrpe_no_ssl as
$USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -n and defining service
as check_nrpe_no_ssl!check_load and running nrpe deamon no centos host
with -n option - result is just the same, NRPE: Unable to read output
However, when I do ./check_nrpe -H centos.host.com it does return me
nrpe version correctly (NRPE v2.12).
From all this steps I figured that it is not about ssl at all - nrpe
version is returned correctly with ssl and without it.
Interesting, that in nagios server debug log I see that remote NRPE
returns output that nagios check_nrpe cannot parse, it returns similar
output, that I would get if call /usr/sbin/nrpe without arguments:
[1277983505.131702] [016.2] [pid=17495] Parsing check output...

host = The address of the host running the NRPE daemon\n
[port] = The port on which the daemon is running (default=5666)\n
[timeout] = Number of seconds before connection times out
(default=10)\n [command] = The name of the command that the remote
daemon should run\n [arglist] = Optional arguments that should be
passed to the command. Multiple\n arguments should be
separated by a space. If provided, this must be\n the last
option supplied on the command line.\n -h,--helpPrint this short
help.\n -l,--license Print licensing information.\n -n,--no-ssl Do not
initial an ssl handshake with the server, talk in
plaintext.\n\nNote:\nThis plugin requires that you have the NRPE daemon
running on the remote host.\nYou must also have configured the daemon to
associate a specific plugin command\nwith the [command] option you are
specifying here. Upon receipt of the\n[command] argument, the NRPE
daemon will run the appropriate plugin command and\nsend the plugin
output and return code back to *this* plugin. This allows you\nto
execute plugins on remote hosts and 'fake' the results to make Nagios
think\nthe plugin is being run locally.\n\n
so that seems to me as if NRPE does not understand arguments from
check_nrpe or something...
any ideas?
