Monitor Webpage without checking keyword

[scheema31]

thanks for quick update jdalrymple.
i updated my files to match your settings however i still get an error for authorization
HTTP WARNING: HTTP/1.1 401 Authorization Required - 681 bytes in 0.034 second response time
is there a way we can try this without having to use authentication, i used have this working just fine but then we upgraded our svn to a newer version and since nagios has been failing.
here is how i had it setup before the upgrade when nagios checks were working fine:

define command{
command_name check_https
command_line /usr/local/nagios/libexec/check_http -S -H $ARG1$ -p 443 -u $ARG3$ --regex=$ARG2$ -w 3 -c 5 -t 10
}
define service{
use pager_generic-service
host_name sv-baysvn-01.baynet.local
service_description - https://svn.bayleaf.com -
check_command check_https!svn.bayleaf.com!VisualSVN!
}

thanks,

[jdalrymple]

In order to check without authorization you'd have to *NOT* require auth on the SVN server, this is unlikely.

This does appear to use basic web auth though, and in my lab the -a argument is working great.

Code: Select all

[root@localhost libexec]# ./check_http -S -H www.somesite.com -p 443 -u /index.html -t 10 -a jdalrymple:password
HTTP OK: HTTP/1.1 200 OK - 15657 bytes in 0.208 second response time |time=0.207982s;;;0.000000 size=15657B;;;0
[root@jrd-cent65-5 libexec]# ./check_http -S -H www.somesite.com -p 443 -u /index.html -t 10
HTTP WARNING: HTTP/1.1 401 Unauthorized - 390 bytes in 0.286 second response time |time=0.285763s;;;0.000000 size=390B;;;0

Same thing for you - from the command line it's working. Just so I can double check your syntax, can you repost your updated command and service definitions?

here are my configs, i had set it up exactly like the example.

define command{
command_name check_https_plain
command_line /usr/local/nagios/libexec/check_http -S -H $ARG1$ -a $ARG2$
}


define service{
use pager_generic-service
host_name sv-baysvn-01.baynet.local
service_description https://svn.bayleaf.com -
check_command check_https_plain!svn.bayleaf.com!scheema:*****! (the "!" is part of the password, would that be throwing anything off?)
}

checks are definiatly made as nagios shows the service in "warning" state
any thoughts?
thanks

[jdalrymple]

(the "!" is part of the password, would that be throwing anything off?)

YES!

Code: Select all

define service {
        host_name                       localhost
        service_description             nobang
        use                             local-service
        check_command                   check_dummy!0!!!!!!!!
        register                        1
        }

define service {
        host_name                       localhost
        service_description             bang
        use                             local-service
        check_command                   check_dummy!0!\!!!!!!!
        register                        1
        }

Hi,

so i have updated my file:
define service{
use pager_generic-service
host_name sv-baysvn-01.baynet.local
service_description https://svn.bayleaf.com -
check_command check_https_plain!svn.bayleaf.com!scheema:*****!\!
}
however im still getting authorization errors:
HTTP WARNING: HTTP/1.1 401 Authorization Required - 681 bytes in 0.042 second response time

thanks,

[jdalrymple]

A couple of things to look at ... mine's definitely working so we should be able to get yours working...

Code: Select all

[jdalrymple@localhost libexec]$ ./check_http -V
check_http v2.0.3 (nagios-plugins 2.0.3)

Make sure we're using the same version

Code: Select all

[root@localhost libexec]# ./check_http -S -H www.somesite.com -p 443 -u /index.html -t 10 -a jdalrymple:password

Note that I specify a -u and argument to go with it. I'm not sure that it should be strictly necessary, but maybe. I suppose that would depend on what the server's expectation is.

Hi,

so i have updated my nagios to Version 4.0.8. however when using your command (./check_http -V) to check version it shows as what it did before. is there another process to update the nagios-plugin?

[jdalrymple]

Nagios Core and Nagios Plugins are not the same pieces of software:

http://www.nagios.org/download/plugins

[tgriep]

Exclamation points are used to separate command arguments, so they need to be treated somewhat differently.

One way to get around using ! in passwords is to do the following

You will need to edit /usr/local/nagios/etc/resource.cfg and enter in a new line with the following:

$USER10$=xyzabc!

and save the file. You will need to type in your password in place of 'xyzabc!'.

Then you will need to edit your command definition like so:

check_command check_https_plain!svn.bayleaf.com!scheema:$USER10$

and save that file. Then run:

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
service nagios reload

and your check should work for you.

thanks tgriep.
i will try your solution after i update the nagios plugins to version 2.0.3
is this the correct procedure to update:
1. mv to old libexec folder ( /usr/local/nagios/libexec )
2. tar xzf nagios-plugins-1.4.16.tar.gz
3. cd nagios-plugins-1.4.16
4. ./configure --with-nagios-user=nagios --with-nagios-group=nagios
5. make
6. make install

are there any additional steps after this?
do i need to restart nagios?
do i need to update the nagios agents?
