Re: [Nagios-users] Fwd: Apache Server configuration for Nagios 3.0

[Jimmyboy]

Hi James,

You are right. '/etc/httpd/conf.d/' does not exist. Unfortunately, I do not
know how to find out the directory, Apache on my system refers to
'/etc/httpd/conf.d/'.

However, I successfully keyed in the 'ScriptAlias' and 'Alias' directives
into my '/usr/local/apache2/httpd.conf' config file (I reinstalled Apache to
the default location). Still, I am getting the same error on doing a 'sudo
make install-webconf'.

=-=-=-=

I had raised a query on the Apache forum, on which of *apache2.conf* and *
httpd.con*f is the *config file* of Apache. I got an answer stating that it
depends on type of installation method followed. If the source files
(.tar.gz) are used, then it is *httpd.conf*, else, *apache2.conf*. So, it is
true in my case.

Based on this, I observed an already installed Nagios setup on a different
machine. It's *config file* is *apache2.conf* (again true, it was installed
using Synaptic Package Manager).

So, I was thinking to try installing using the 'Synaptic Package Manager' or
'apt-get'. However, both aren't working for me. Though I am able to proxy
the internet (sitting behind a proxy server), Synaptic & sudo apt-get say,
they cannot resolve 'archive.ubuntu.com', etc.

Any idea, how to go about?

Thanks,
Jim

[Nagios-users] Consolidating Log Files

[Christopher McAtackney]

Hi all,

I'm thinking of setting up my Nagios system in a "Redundant
Monitoring" configuration - two servers (a primary and secondary)
which both monitor all hosts / services, but only one of which has
notifications enabled (the primary).

Upon failure of the primary, the secondary will enable its own
notifications (and upon the primary returning to an OK state,
notifications will be disabled).

One aspect of this that I am wondering how to tackle is consolidating
my log files after a failure has occurred.

I want my primary Nagios server's log files to reflect the total
history of check results that have been made - and so would like the
results from the secondary server for the time period when the primary
was done, to be consolidated into the log files of the primary (for
browsing through the web UI).

Has anyone looked into this before, and how did you solve the problem
of duplicate result checks being created in the primary log?

Cheers,
Chris

[Nagios-users] Limit the alert notifications

[Martyn]

Hi all
I would like to change the email alerts per users if I may, is there a way
of setting up so only 3 mails get sent to users "A" but only two mails to
user "B" even if the fault is still there, if not per users then across the
board.

I have searched around but finding anything, not sure if I'm searching for

Marc answered me in similar vein recently, and I am now using it, but  
I made a rather odd discovery. This

host_name !host17, host*

works whereas this

host_name host*, !host17

produces this error at start:

Reading configuration data...

Error: Could not find any host matching '!host17' (config file '/etc/ 
nagios3/conf.d/MM-snmp-checks.cfg', starting on line 49)

It seems that you can't place a negative match after a wildcard.

[Nagios-users] nagios plugin configure:3377: error:

[Tobias Exner]

Dear list,

I've got a problem while compiling the nagios-plugins on a suse 10 box.

I already searched through the web, but I didn't any helpful information.
As I understood the compile needs the path 
/usr/lib/gcc/i586-suse-linux/4.0.2/include

I don't know if that's right and how to fix it.

The path does really not exists.

Thanks in advance...

Ping and those services that I consider critical on the specific

max_check_attempts 2, notification_interval 10. Looks like you just  
need to change check_interval. I use --

 check_interval   5
 retry_interval3
 max_check_attempts  3

What would you suggest? The names seem obvious to me but I may be  
jaded. The documentation is pretty clear on what they mean/do as well,  
at least to me.

Real life examples are provided in the sample config files (or used to  
be). The documentation links that may help you are (some redundancy  
between them) --

http://nagios.sourceforge.net/docs/3_0/statetypes.html
http://nagios.sourceforge.net/docs/3_0/activechecks.html
http://nagios.sourceforge.net/docs/3_0/servicechecks.html
http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#service

And this one from the -2.0 docs that nicely explains much of the  
scheduling... It's a little dated wrt host checks but for the most  
part is a good read--

No. Nagios expects the files to be 'local'. That being said, I expect  
that the previously mentioned lufs, nfs (for certain, I use it) or  
other network filesystems you can mount should work for the config  
files...

Hi

./check_by_ssh -l myuser -H myhost -t 120 -C myscript my_script_argument


The script gives an output as if the my_script_argument is empty

[Nagios-users] monitoring critical servers - best practices

[alfonso baldaserra]

Greetings,

We are using Nagios version 3.0.6 on Fedora core 9.

I was just looking for some ideas how do you guys monitor critical servers
and services, what are the best practices etc.?

On a related note I just figured we have been missing a lot of alerts
lately.  Today we had to reboot couple of AIX servers which usually takes 5+
minutes.  Interesting thing is we did not receive any notification for these
servers.  Below is the host configuration entry

define host{
name aix-server  ; The name of this host
template
use  generic-host; This template inherits
other values from the generic-host template
check_period 24x7; By default, Linux hosts
are checked round the clock
check_interval   2   ; Actively check the host
every 5 minutes
retry_interval   1   ; Schedule host check
retries at 1 minute interval
max_check_attempts   2   ; Check each Linux host 10
times (max)
check_commandcheck-host-alive ; Default command to check
aix hosts
notification_interval10  ; Resend notifications
every 2 hours
notification_options d,u,r   ; Only send notifications
for specific host states
contact_groups   aix-team; Notifications get sent to
the admins by default
register 0   ; DONT REGISTER THIS
DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!
}

I was just wondering what do I need to change if:

a server goes down
nagios check after 1 minute, as usual, and finds the server is down
nagios checks again after a minute and finds the server is still down
nagios sends notification and keep on sending notification after every 10
minutes until the server comes up again

I have checked nagios archives for check_interval, retry_interval and
max_check_attempts and as a result I got totally confused.

Any help is much appreciated.

P.S.  I request nagios developers to either change these options to
something more meaningful or provide some real life examples.  Apparently
there are many users which have been confused by these options as seen in
archives.

Thanks

I looked for the before, and there's definitely only one nagios instance 
running.   The problem persists across nagios restarts and reboots.

Thanks

Re: [Nagios-users] Customize "service detail" page

[borkmann]

thanks for your answers!

i'm just wondering how nagiosgrapher got their grapher icon into the 
service
page ... i mean ... at first view they doesn't seem to have any patched 
c file or
command.

in their configuration (ngraph.ncfg) they have sth like this:

icon_image_tag  ' dot.png' alt="___ALT___" border="0"> I've heard of people achieving something similar by running the

You don't have more than one instance of the Nagios daemon running do
you?  Try stopping the Nagios daemon, make sure all instances of
nagios are stopped (using ps -ef | grep nagios), and kill any which
remain then start the Nagios daemon using /etc/init.d/nagios start .

hth,

Jim

You can indeed do that.  I do something similar myself to check all
Wintel servers, but not those in a group called 'BRONZE'.

Cheers,

Jim

I've recently been seeing many of the following kind of errors appearing

The only two references I can find for this error are:

which is inconclusive, and my own Debian bug report at:

(you can see nagios package and version details here, too).

Any insights as to what might be causing these errors?

[Nagios-users] Can you not check a certain hostgroup?

[Andrew Bruce]

Is it possible, in a service definition to tell the service to not check a
group of hosts? 

For example, I have a hostgroup that contains some basic checks for every
Windows server. 

But some of the servers are still on NT, so don't support a particular
check, and I want to disable it for just these servers. Can I have a
hostgroup called WinNT_old with the servers I don't want to run this
particular check against and then do a service check with the hostgroup
like (or similar): 

hostgroup_name Win_All, !WinNT_old 

Thanks, 

Andrew--
