check_http problem (very strange)

[sikainfo]

Hi there,

we do have a problem with a customized http check.

/usr/local/nagios/libexec/check_http -H XYZ.sika.com -S -u https://XYZ.sika.com/webconsole/app\?page=Login -p 443 -w 5 -c 10 -l

running this check with the test button in the CCM works fine

COMMAND: /usr/local/nagios/libexec/check_http -H XYZ.sika.com -S -u https://XYZ.sika.com/webconsole/app\?page=Login -p 443 -w 5 -c 10 -l
OUTPUT: HTTP OK HTTP/1.1 200 OK - 25519 bytes in 0.070 seconds |time=0.069714s;5.000000;10.000000;0.000000 size=25519B;0;0;0

running it on Unix commandline works fine
running it with NagiosXI brings following Error

(Return code of 127 is out of bounds - plugin may be missing)

Any clou ?

Hmm odd, what are the permissions on the plugin, and what is the path?

[sikainfo]

Below you find the path (standard) and the permissions which are set on this plugin:

-rwxr-xr-x 1 root root 468776 Apr 4 2012 /usr/local/nagios/libexec/check_http

this looks pretty standard and the same plugin runs fine against other windows Servers.

Try altering the permissions to nagios.nagios:

Code: Select all

chown nagios.nagios /usr/local/nagios/libexec/check_http

[sikainfo]

As you see running the command from the same machine, after i changed the user and group like you proposed, did not change anything.

Running on system prompt:

Code: Select all

[root@chsismon1 ~]# /usr/local/nagios/libexec/check_http -H blackberry.sika.com -S -u https://blackberry.sika.com/webconsole/app\?page=Login -p 443 -w 5 -c 10 -m 25000:25600 -l -t 30

Running through NagiosXI:

Have you tried wrapping the URL in single or double quotes? Can you post the service and command definition?

[sikainfo]

Hi,

below you find the service and command definitions: (before ai made the test with quoting the URL

Code: Select all

define command {
       command_name                             check_https_url
       command_line                             $USER1$/check_http -H $ARG8$ -S -u $ARG1$ -p $ARG2$ $ARG3$ $ARG4$ $ARG5$
 $ARG6$ $ARG7$

Code: Select all

then I made the test with Quoting and ..... it works in the normal UI!
but running the test under ccm and directly on the commandline it does not work.

Fine it works for me, but still why it is not constantly under all UI's ????

[abrist]

The "test check command" in the CCM web ui has only limited privileges. It can only run tests as user apache, not as user nagios. Additionally, it does not have access to user defined macros.

[sikainfo]

I still not understand fully why, especially that fact that it runs without quoting and doesn't with quoting under Test and OS prompt, has not any link to the permissions of a User for me.
Anyway the problem is solved for me and you my close this thread.

Thank you

Andy

This is because it is not running your web UI under nagios, it is running it under Apache, so Apache has to be the one in the end who executes the checks done through the Test Check Command.
