Re: [Nagios-users] CheckEventLog Info
That is a great resource. Thanks. One question I have is on defining the $ARG1$ etc. For example: Check for errors by eventid in the last 2 hours. $ARG1$ = file to check ie. Application, Security, System $ARG2$ = Max Warn amount $ARG3$ = Max Critical amount $ARG4$ = eventID Number Than: ./check_nrpe -H $HOSTNAME$ -c CheckEventLog -a filter=new file=$ARG1$ MaxWarn=$ARG2$ MaxCrit=$ARG3$ filter-generated=\2h filter-eventID==$ARG4$ filter-eventType==error filter=in filter=all My question is where are these ARG's defined. Where does NRPE know to lok to determince that ARG4= EventID. Is there a config for that? I looked through the different cfg. Files and didn't see that.

Re: [Nagios-users] Help - I am unable to send notifications
Sure, the issues encountered were pretty well documented in the thread. Basically it was an error with a return code of 136 when trying to send the notification. The app I was using was a Perl script send_mail.pl that was using #!/usr/bin/perl -w. To be honest we never fixed that specific issue. We ended up installing net-qmail and using it as an MTA and sending mail out directly using printf. Basically default Nagios commands.cfg file. That solution worked very well.

[Nagios-users] Notification using notify-html-email.sh
Reposted with apologies:
After giving up on the send_mail.pl script I am going with the
notify-html-email.sh add-on. I seems pretty straight forward. One
question on a command. The command to run when notifying service alerts
reads:
define command {
command_namenotify-html-email
command_line/usr/local/nagios/libexec/notify-html-email.sh
service
}
I get this error in the nagios log:
[1217000677] Warning: Attempting to execute the command
/usr/local/nagios/libexec/notify-html-email.sh service resulted in a
return code of 127. Make sure the script or binary you are trying to
execute actually exists...
Sounds familiar. Nagios is the owner and I also ran chmod
0755 /usr/local/nagios/libexec/notify-html-email.sh. That is
definately where the file is and permissions are good.
I am wondering about the fact that service is after it. There is no -
or / or anything before that. The error looks like it's trying to find
a file called notify-html-email.sh service rather than the file
notify-html-email.sh with a parameter of service.
I have attached the script it is running.
notify-html-email.sh
Description: notify-html-email.sh

Re: [Nagios-users] Help - I am unable to send notifications
I have decided on another course of action. I have spent way too much time with no success on this issue. I just can't get this script to work. Are there any other recommended plug-ins that anyone can recommend. The native e-mailer did not work either and when on the Nagios Wiki I found this about it: by default, nagios uses 'mail' or 'mailx' to send it's email. The actual mail command is found in the default commands.cfg file /usr/local/nagios/etc/objects/command.cfg there are two definitions by default 'notify-host-by-email' and 'notify-service-by-email' in each of these definitions, there is a command_line; this is what nagios executes in order to send mail using the mail or mailx system (varies from system to system) and it *may* need to be changed in order to work - although I must admit to not having much success so far with it myself :( (see forum thread -- Perhaps I'll go back to the native mailx mailer and try that again and reset my commands.cgf back to how it was. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jay R.

Thanks Andreas,
I that fixed the code 126. The nagios.log has no errors now. I am
still not getting any notifications, but I can troubleshoot further. I
am curious about one thing. The send_mail.pl script specifies a mailto
address in the SMTP setting my $mailto = [EMAIL PROTECTED]
The contacts.cfg also specifies an email address in the define_contacts{
section. I guess I am wondering which one it uses to determine where to
send the notification.

amiss or the perl is not working or something? I am not sure.

Due to some weird and slightly bent way of passing errors between
processes, return code 126 means Operation not permitted. In
english, that means the script is not executable, or one of the
directories leading up to it isn't readable by the Nagios user.
Run this command (as root):
chmod 0755 /usr/local/nagios/libexec/send_mail.pl
(correct the path if necessary)
and things just might start working a little better.

If this is a double post I apologize, I just did not ever see it go
through and do not see it in my sent items or drafts. The error code
126 is gone and see what appears to be a successfull notification in
the nagios log:

Thanks. And yes there was a #! In front as you said. I did say similar just because the OP who was helping me said I would get something similar to #!/usr/bin/perl args-to-perl. My output was similar to that, but not exact. Thanks for the response. I ran the following: sed -i '1s,.*,#!/usr/bin/perl -w,' check_sendmail.pl return: sed: can't read check_sendmail.pl: No such file or directory I been following your Emails on this issue and it looks like this must be some simple mistake somewhere, for example runtime Libexec is not the directory your using, FIlemames mispellings, things missing from the path or some other unkown issue. Try running some normal shell script that just gives a date or pwd to validate the Libexec directory you are copying files to is the one nagios is run from. In the above command was it suppose to be sendmail.pl instead of check_sendmail.pl ? (I am not sure I did not think hard about what the command does) but most of the prior emails mentioned only sendmail.pl while check_ is common prefix of most common nagios plugins. Last in prior posts I noticed the -n in the command has a space between the - and the n is it really there or is it just my email reader? if it is there should it be there? Tony (Author of NC_net) (I actually prefer reading Top posted msg - but I understand Andreas point on Bottom posting or inline posting) Good question Tony. There is no such file called check_sendmail on my system. Other scripts are running fine out of /usr/local/nagios/libexec. I am not sure if perhaps the send_mail.pl script is perhaps looking for the pearl binary in the wrong folder /usr/bin/perl as opposed to /usr/local/bin/perl? I am not at work now but will dig in later tonight. I am a victim of my own lack of Linux experience here I admit, but I'm learning. I have a feeling if any of you were looking at everything I have here it would jump out at you. I'm going to team up with a colleague of mine here who is a good Linux guy and get his input as well. As usual thanks again for your time and expertise. Jon

I am guessing (with all my vast linux experience...that's sarcasm) that
perhaps the send_mail.pl wrapper does not know how to find the actual
senmail file which is located in /usr/lib. I don't see anything in the

PERL is not what tries to load the file initially, the shell tries to load the file as a compiled program(like /bin/ls is the compiled program that lists the files in a directory: I ran this on my nagios server as an example): [EMAIL PROTECTED] nagios]$ file /bin/ls /bin/ls: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), stripped [EMAIL PROTECTED] nagios]$ But since a PERL script is interpretted and not compiled (technically that isn't true either but it might as well be), the loader normally doesn't know what to do with it, so the gods of UNIX decided that the characters #! Would have special signifigance to the loader at the beginning of the file. They indicate the program that will interpret the script. So when the loader sees it it then looks for the /usr/bin/perl program and execs it with the -w command and the script path so that it will interpret the script. If /usr/bin/perl does not exist you will have problems. To verify the existence of it just ls /usr/bin/perl. Most systems have it there, but a few do not, instead they keep it in /usr/local/bin/ so you might need to change that line to #!/usr/local/bin/perl -w instead. But only if it is in that location, if it isn't you will need to find it. Which may not be so hard since nagios probably found it when you installed it and if you do a file * in the plugin directory and then type head and the name of a perl script you should see where it really is. Hope this helps. That helped a great deal in helping

I have yet to see you confirm that send_mail.pl actually exists. None
of my default installs have this script, so I'm assuming that's your
problem.
Download it from NagiosExchange
(http://www.nagiosexchange.org/cgi-bin/page.cgi?g=2217.html;d=1) and
put
it wherever $USER1$ is (this is the default location of check_x

It does exist and I pasted the text from it in a previous e-mail earlier
today. I downloaded it from nagiosexchange as an add-on so no default
Nagios install would have this. It is located
in /usr/local/nagios/libexec. See below:
[EMAIL PROTECTED]:/usr/local/nagios/libexec# locate send_mail.pl
/home/zlocaladmin/Documents/send_mail.pl
/usr/local/nagios/libexec/send_mail.pl
[EMAIL PROTECTED]:/usr/local/nagios/libexec#
The /home/zlocaladmin/Documents/send_mail.pl reference is where the file
was downloaded and I copied rather than moved it into
the /usr/local/nagios/libexec folder so that one is not being used. I
have looked this over and over and can't figure out why it says it does
not exist. It's there.

I verified that sendmail as well as printf and they are both there and located at the specified paths mentioned. I was looking through the send_mail.pl script and could not find where these two apps are called as well as uuencode and the date command. I had assumed that send_mail.pl was a replacement for sendmail and printf by reading the documentation. By reading the script I don't see anything to edit. Thanks again for all your input.

Re: [Nagios-users] Help - I am unable to get the NSClient++ torestart services
Lets try this again... I figured everyone had given of their time and knowledge to me that I'll try to repay the favor. I made a translation from Portuguese to English of the opmonagent.ini and the service-control.cmd files and have attached them if anyone is interested. It really helped me to understand what these files do and hopefully I can get these services restarted now. Is there any manipulation of these files that is necessary to get services restarted besides the general opmonagent.ini file editing for port #, allowed from IP, etc? They are attached as txt files as I couldn't send them the first attempt as a cmd file. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jay R.

OK. OpMon is running on the test server and my define_command for spooler
restart reads exactly as you posted, still no service restart. I am still
missing something. I am not sure if I need to edit anything in the
OpMonagent.ini or service_control.cmd.

Jonathan,
The client installed on the host doesn't matter if both of them have support to
nrpe. They will have a configuration file where you'll define the commands to
run over check_nrpe.
NSClient++ uses NSC.ini
OpMonAgent uses opmonagent.ini
But to make it easy, the OpMonAgent has a command to restart services built-in
his configuration file.
So, if you have the OpMonAgent running on host, you just need run the following
command from your nagios server:
/usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c
service_control -a spooler start
But, if you are using NSClient++ you need define a command into the
configuration file first, then you'll use this command in the check_nrpe.

to restart a service. I have NRPE now running on the server under xinedt, and
switched the client back to NSClient++ from OpMon Agent. Both support NRPE. I
am not sure if I am supposed to get a service restarted with a NRPE_Check
command like:
/usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c
service_control -a spooler start
Or am is supposed to create scripts on the host that will restart a service
like a .bat file with a net start spooler command and than get an
event_handler set up to call that script. It seems there are different ways to
do it and I am being pulled both directions. I am new to Nagios as well as
Linux and have been able to scrap my way thus far while learning a lot about
both, but am about ready to call it quits. I was pointed to the NakedNuns
website to the section on CheckExternalScripts, but honestly could not make
much sense of it.

Jonathan,
make sure that you have the xinetd installed and check if there is the
following directory:
[EMAIL PROTECTED] ~]# ls /etc/xinetd.d/
chargen-dgram daytime-dgram discard-dgram echo-dgram eklogin
gssftp krb5-telnet ktalk rsync time-dgram
chargen-stream daytime-stream discard-stream echo-stream ekrb5-telnet
klogin kshell nrpe tcpmux-server time-stream
if you don't have that, try to install by apt-get!
and then, run the command again
Make install-xinetd
or you can install just writing a file like this:
[EMAIL PROTECTED] ~]# cat /etc/xinetd.d/nrpe
service nrpe
{
flags = REUSE
socket_type = stream
wait = no
only_from = 127.0.0.1 (PUT YOURS NARIOS SERVER'S IPS HERE)
user = nagios (PUT THE NAGIOS USER HERE)
server = /usr/local/nagios/libexec/nrpe (THE NRPE SERVER)
server_args = -c /usr/local/nagios/libexec/nrpe.cfg --inetd (THE NRPE
CONFIG FILE)
log_on_failure += USERID
disable = no
}
and then restart xinetd!

I was able to compile that without ssl and was able to install the pugin's

Make install-plugin
Make install-daemon

Those worked finer however the next step says:
Install the NRPE daemon as a service under xinetd

Re: [Nagios-users] Help - I am unable to get the NSClient++ to restart services
OK.. I am getting somewhere now. I manually ran this command from the Nagios
server terminal:
/usr/local/nagios/libexec/check_nrpe -H 10.10.113.51 -p 5666 -n -c
service_control -a spooler start
And it worked!! Meaning the OpMonagent works! Now I jst need to find out why
it will not work as an event_handler like so:
Define service{
Use generic service
Host_name jwilliamspc
Service_description PrintSpooler
Check_command check_nt!SERVICESTATE!-d SHOWALL -l Spooler
Event_handler restart_Spooler
}
define command{
command_name restart-Spooler
command_line PATH/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c
service_control -a Spooler start

OK. OpMon is running on the test server and my define_command for spooler
restart reads exactly as you posted, still no service restart. I am still
missing something. I am not sure if I need to edit anything in the
OpMonagent.ini or service_control.cmd.

Jonathan,
The client installed on the host doesn't matter if both of them have support to
nrpe. They will have a configuration file where you'll define the commands to
run over check_nrpe.
NSClient++ uses NSC.ini
OpMonAgent uses opmonagent.ini
But to make it easy, the OpMonAgent has a command to restart services built-in
his configuration file.
So, if you have the OpMonAgent running on host, you just need run the following
command from your nagios server:
/usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c
service_control -a spooler start
But, if you are using NSClient++ you need define a command into the
configuration file first, then you'll use this command in the check_nrpe.

That is exactly the syntax I am using and it did not work with OpMon agent.
Perhaps I had a bad opmonagent.ini file. Here is all it has:
[OPMONAGENT]

allow_from=192.168.1.94

Than there is a a [NRPECOMMAND]section but everything else is in Spanish so I
can make use of it. Is there a link to another opmonagent.ini file. The one I
have has no commands but does have this:
service_control=c:\opmon\service-control.cmd $ARG1$ $ARG2$
However there is no services-control.cmd file in the opmon folder. This looks

service_control -a spooler start
Or am is supposed to create scripts on the host that will restart a service
like a .bat file with a net start spooler command and than get an
event_handler set up to call that script. It seems there are different ways to
do it and I am being pulled both directions. I am new to Nagios as well as
Linux and have been able to scrap my way thus far while learning a lot about
both, but am about ready to call it quits. I was pointed to the NakedNuns
website to the section on CheckExternalScripts, but honestly could not make
much sense of it.

Jonathan,
make sure that you have the xinetd installed and check if there is the
following directory:
[EMAIL PROTECTED] ~]# ls /etc/xinetd.d/
chargen-dgram daytime-dgram discard-dgram echo-dgram eklogin
gssftp krb5-telnet ktalk rsync time-dgram
chargen-stream daytime-stream discard-stream echo-stream ekrb5-telnet
klogin kshell nrpe tcpmux-server time-stream
if you don't have that, try to install by apt-get!
and then, run the command again
Make install-xinetd
or you can install just writing a file like this:
[EMAIL PROTECTED] ~]# cat /etc/xinetd.d/nrpe
service nrpe
{
flags = REUSE
socket_type = stream
wait = no
only_from = 127.0.0.1 (PUT YOURS NARIOS SERVER'S IPS HERE)
user = nagios (PUT THE NAGIOS USER HERE)
server = /usr/local/nagios/libexec/nrpe (THE NRPE SERVER)
server_args = -c /usr/local
Re: [Nagios-users] Help - I am unable to get the NSClient++ to restart services
I am having a little trouble installing the NRPE 2.8 plug in Ubuntu. I
am able to extract the source code tarball and than I am having issues
after that. Per the instructions I am trying to compile the NRPE add-on
by running
./configure
make all
After I type ./configure I get a message at the end of the compile job
saying configuration error: Cannot find ssl libraries. Than if I try
to go further by installing the plugins by typing make all or the
individual make install-pluggin I get an error saying ** No rule to make
target 'all'. Stop.

I found the NRPE add-on (not plug-in) so I will download and install
that. I'll let you know if I run into anything. You have been more
than helpful.
Thanks,

check_nrpe is part of the package nrpe, if you use ubuntu, I believe
that only an apt-get install nrpe solve your problem.

The commando must be:
define command{
command_name restart-Spooler
command_line PATH/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c
service_control -a Spooler start
}
ex:
define command{
command_name restart-Spooler
command_line /usr/local/nagios/libexec/check_nrpe -H
$HOSTADDRESS$ -p 5666 -n -c service_control -a Spooler start
}
risk being sent to /dev/null

[Nagios-users] Help - I am unable to get the NSClient++ to restart services
Hello everyone, I am new to Nagios and am looking for some help. I
already posted this in the forum as well. I can successful get Nagios
to monitor any service I need, but I can't get it to restart. Here is
my situation up to date: (from the forums)
I did make sure event handler was enabled, but the documentation refers
to scripting the start up of linux services, not Windows. I figured I
can create a .bat file to do a simple net start, but how does Nagios run
it? Is it something like this? (example of the server service)
define service{
host_name somehost
service_description Server Service
max_check_attempts 4
event_handler restart_server
}
Than for the handler command:
define command{
command_name restart-httpd
(This is where I am unsure. Do I give it a path to the .bat file?)
Is nagios able to run this file from the host PC. In these linux script
examples I am unsure if the script is on the Nagios server of the host
server. Any help would be awesome. Hopefully I'm close to accurate here.
I got a reply:
You can use NRPE/NSClient++ and instead of using it to run remote
scripts to check something, use it to restart your services. See
http://nagios.sourceforge.net/docs/3_0/monitoring-windows.html
http://trac.nakednuns.org/nscp/
However still cant get NSClient to start the service. The links
provided detail how to set up monitor host services. This works great.
However I cannot get the NSCLient++ to actually restart the service. I
edited the NSC.INI file to comment out the check_all_services section
and have the values set to started however it still shows the service
as stopped and it will not restart it. I am assuming there is a step I
am missing in this in some config file somewhere. Any help would be
greatly appreciated as I am under a deadline to have this up by this
weekend. Management thought this would be easier than it is and gave me
two days.
Any help on what I am missing would be greatly appreciated.
