[Nagios-users] Notification not sending email.

[Neil Marjoram]

I'm having a little trouble with notifications. 




I can't workout why Nagios is not sending alert emails. I have read
the documentation, FAQ's and mailing lists and have concluded it
is only me that can't get it to work. Can someone have a look at
my configs below to see if I have done anything wrong. I loaded
up Nagios QL to check I am configuring the files correctly but
it has made no difference. Running the command for email on the
command line works (although it errors because of the variables)



Many thanks,



Neil.

Re: [Nagios-users] Notification not sending email.

[Neil Marjoram]

Deborah,

I have tried the mail command on the command line, and it works fine, I 
have even copied the definition in, changed the variables and tried 
that, which also works. Here are the 2 definitions for email that are in 
misccommands.cfg :


define command{
   command_namehost-notify-by-email
   command_line/usr/bin/printf "%b" "* Nagios  
*\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: 
$HOSTSTATE$\nAddress:
$HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | 
/bin/mail -s "Host $HOSTSTATE$ alert for $HOSTNAME$!" $CONTACTEMAIL$

   }
define command{
   command_namenotify-by-email
   command_line/usr/bin/printf "%b" "* Nagios  
*\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: 
$SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: 
$SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional 
Info:\n\n$SERVICEOUTPUT$" | /bin/mail -s "** $NOTIFICATIONTYPE$ alert - 
$HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$

   }

Many thanks,

Neil.

[Nagios-users] Re: [Nagios-devel] (Feat-req) Making hostgroups member of hostgroups

[moshe sharon]

Hello
 
it can be done by making a room1-template, room2-template etc.. and apply all your needs(active, passve, normal_check_interval...)
of course dont forget to register 0 after that make another template called windows-servers-room1 unix-servers-room1 and then add "use room1-template" in the template and at last at the service entry put use windows-servers-room1 and hostgroup_name "groupname". 

 
hope i understand correctly

Re: [Nagios-users] Notification not sending email.

[Neil Marjoram]

OK I have just removed the nagios rpm from Dag and recomplied from 
source using Dags' options, notifications are now working, using my old 
config files. I am still using the RPM's from Dag for everything else.


Many thanks,

Neil.

RE: [Nagios-users] Setting threshold value for services to get alert

[Mrutyunjaya Dash]

Hi All,

I have a very specific requirement to send out alert in the case when
the disk space exceeds particular threshold value for the particular
filesystem. Can anyone help me out to share the information, how this
can be done.

http://nagios.sourceforge.net/docs/2_0/notifications.html

The basic process is that when a plugin is executed and returns a non-OK
state up to max_check_attempts, the host or
service_notification_commands are executed for each contact in that host
or service's contact_group (after passing the filters mentioned in the
notification documentation). The sample config files provide example
host and service notification commands.

There is a documentation error. You have to use real regex. A naked * by
itself is not a valid regex.

Try .*

So we've installed the latest version of "nrpe" on a server (normal configuration). Then we installed "nrpe_nt" on a windows 2003 server machine and it works fine. We're also trying to run "nrpe" (for hosts) as a standalone deamon on a linux machine but we've compiled it without SSL (mainly because it wouldn't allow use to compile it, even with openssl (missing libraries)... so we're running the standalone deamon with the -n option). 
When we installed the 2.3 version, I was kinda surprised that the "allowed_hosts" command in the config file didn't work anymore and we also got that error : "CHECK_NRPE: Socket timeout after 10 seconds.", so we thought it had something to do with the "allowed_hosts" command in the config file. We were also getting an error in the "/var/log/messages" file saying : "(date) slxids nrpe[9493]: Could not read request from client, bailing out...".
So we deleted the newest version and installed the 2.0 version of NRPE (without SSL again). So the "allowed_hosts" command is back, but the -n option when we lauch nrpe as a standalone deamon isn't there anymore... and we're still getting the same errors.
Anybody has an idea of what's going on? Is it because of SSL?

Look at 'check_disk --help'. That, combined with the notification and
host/service configuration documentation should get you going.

[Nagios-users] Internal Server Error on Nagios 2.0

[Pete Shelfo]

I recently tried to fire up a new Nagios server running on
RedHat 4 Enterprise (fully patched).  Everything works fine, pre-flight
passed, http is correct, web page displays; however, whenever I access a CGI
link on the left hand page I get the following error:

“Internal Server Error
The server encountered an internal error or misconfiguration and was unable to
complete your request.
Please contact the server administrator, [EMAIL PROTECTED] and inform them of the
time the error occurred, and anything you might have done that may have caused
the error.
More information about this error may be available in the server error log.

I have tried and tried to troubleshoot the problem but have
had no success. 

1.  I have searched the forums, google and apache.  It appears this is
a common problem across many Linux platforms

2.  I have chmod 777 /usr/local/nagios permissions fully with no success
and added every userID I could like of to the group.

3.  I have even tried a default configuration with one host, a check ping
and along with all the sample configs.  The problem still occurs.  

4.  I have verified my http conf and tried all types of suggestions I found
during my searches.

My http config error log displays the following:

Tue Feb 21 10:43:50 2006] [error] [client 10.1.7.200]
Premature end of script headers: status

.cgi, referer: http://servername/nagios//side.html

I am currently running Nagios version 1.1 with no
issues.  This really looks like an incompatibility with Apache or CGI or
something?  Anyone have any ideas – I am flat out?

I think if you made the font bigger we could help more.

It's a common problem, but it has many (simple) solutions.  This is an
apache-related problem, not Nagios, though.  You'll find it.

Your permissions or authentication via website is not correct
(REMOTE_USER isn't being set). For RHEL systems, using the rpms
provided by dag make things much easier, as the permissions etc are
done for you. All you're left doing is adding users to the web
authentication setup he provides and configuring services, or changing
his auth to whatever auth system you use in your env. They work very
well.

Look at check_website or webinject on nagiosexchange. Both plugins let
you get much more in-depth as far as website checks. For example, we
do an indepth (check_website) check once an hour, and more frequent
checks of "is the website responding"(check_http).

Title: Message



Pete, it sounds that you forgot to put in place the user that you're 
logging in. At CGI.cfg file there's a SYSTEM/PROCESS INFORMATION ACCESS 
parameter that you use to tell to Nagios who has the permission to view your CGI 
links.
 
# 
SYSTEM/PROCESS INFORMATION ACCESS# This option is a comma-delimited list of 
all usernames that # have access to viewing the Nagios process information 
as# provided by the Extended Information CGI (extinfo.cgi).  By# 
default, *no one* has access to this unless you choose to# not use 
authorization.  You may use an asterisk (*) to# authorize any user who 
has authenticated to the web server.

The URL you're checking is returning a 302 REDIRECT. There is no HTML to
look at. You'll probably want to add '--onredirect=follow' and either a
-s, -R or -e string check based on your needs.

I would expect Apache to be providing more useful information in the
error_logs. At any rate, do you have SELinux enabled? Have you verified
that you are not experiencing restrictions based on that. I would also
try running status.cgi from the command line as a non-root user to see
if you experience any errors that way. It's not a perfect test but it
may provide some insight. I doubt it's a compatibility issue. Probably
SELinux or some library that isn't where it's expected. Were the CGI's
compiled on this machine? You might try running 'ldd status.cgi' and
make sure that the libraries are where they're expected and readable by
your apache user.

[Nagios-users] statusmap questions

[Mike Linden]

I am monitoring a large number (650) of linux systems in a cluster environment.  I would liketo have the statusmap display these systems as they are physically setup in their racks.I have currently got the statusmap working but I have 2 issues with the display
First, I get a green circle with cross hairs for each host which I would like to not see.  I only need the words up/down to display.Second, I would like to actually have pictures of the racks with system icons.  Has anyone seen
this type of map?ThanksMike-- 

Re: [Nagios-users] statusmap questions

[Toto Capuccino]

On the stausmap page you got a scrolling list called Layout method, it looks like the one you want is circular. If you want icons to be displayed you need to create a hostextinfo.cfg file you'll find in nagios doc how the cookie crumbles. Check also nagiosexchange to find nice icons, there's some reprsenting racks with flags for OS.

   Have a look at Extended Host Information 
(http://nagios.sourceforge.net/docs/2_0/xodtemplate.html#hostextinfo). 
Another nice option for visual status maps is NagVis 
(http://www.nagvis.org/); have a look at version 0.9, it's really easy 
to configure and nice to see :)

[Nagios-users] seg fault exiting downtime

[David Schlecht]

Hi All,



After extensive testing, I've been able to isolate this seg fault.
 I'm still uncertain if this is related to a configuration setting,
 or if it's a bug in Nagios. If anyone has any input, I would certainly
 appreciate hearing from you.



I can reproduce this on the following platforms:

SuSE8 on I386, Nagios v1.2

SuSE9 on Z/VM, Nagios v2.0a1

SuSE9 on I64, Nagios v2.0b4



The log file shows:

Any ideas?

what happens when you run the status.cgi from the command line as the
apache user?

is this error happening with *all* cgis, or just this one?

'Premature end of script headers' *almost always* means the cgi is
throwing an error (before completing headers the browser can
understand).

The best place to start is pasting in the error, in quotes, into google:

RE: [Nagios-users] Internal Server Error on Nagios 2.0

[Pete Shelfo]

I found the answer!!!  Unfortunately installing Nagios via the RPM did
not help.  The problem lies within SELINUX.  If I disable SELinux the
CGI scripts work fine.

/etc/selinux/config 
SELinux=disable
Reboot the server

Now the question is why does the security enhanced Linux module cause
problems with the CGI scripts?  I value a secure Linux server so I am
off to research some more.

Your permissions or authentication via website is not correct
(REMOTE_USER isn't being set). For RHEL systems, using the rpms
provided by dag make things much easier, as the permissions etc are
done for you. All you're left doing is adding users to the web
authentication setup he provides and configuring services, or changing
his auth to whatever auth system you use in your env. They work very
well.

[Nagios-users] (U) Statsmap visual indicator

[Cook Robin K Civ CPSG/ZCI]

Classification: UNCLASSIFIED

Is there a way to get the status map (user defined) to display an indicator
for a host when a service associated with that host has a problem?  I would
rather not have icons for the services on the status map as it is busy
enough as it is.

[Nagios-users] hostgroupescalations not working

[Derek J. Balling]

I'm running the latest version of Nagios included with Debian sarge/ 
stable (it reports itself as 1.3-cvs.20050402-2.sarge.1).


I have defined, in /etc/nagios/escalations.cfg, a  
hostgroupescalation, like so:


define hostgroupescalation{
hostgroup_name  all-linux
first_notification  3
last_notification   0
contact_groups  oncall,sysadmins-pgr
notification_interval   5
}

... thinking that from escalation point 3 and up, the oncall person  
and the sysadmins will get notified every five minutes.


Except that it never seems to get processed. The "default"  
contact_groups, from the services declaration, all get their notices,  
but the escalation-people never get theirs.


I created a service escalation (for the service I've been using to  
test the escalation), and it worked just fine (it's now commented out  
though as I try to get the hostgroupescalation to work):


#define serviceescalation{
#   host_name   smtp03
#   service_description SMTP
#   first_notification  3
#   last_notification   0
#   contact_groups  oncall,sysadmins-pgr
#   notification_interval   5
#}

... so I know that the escalations.cfg is being processed, and it's  
*willing* to escalate, just not to escalate for a hostgroup.


I confirmed that smtp03 *is* in the "all-linux" hostgroup  
declaration, and it appears there in all the GUI locations, so it's  
not that the hostgroup simply doesn't match the server in question.


What am I missing? Is this some stupid typo that I'm not noticing?  
The members of the service's contact_groups field all get their  
notices, but the people it's supposed to escalate to don't. What am I  
missing?


Thanks much!

Cheers,
D
