Nagios Support Forum

Hi,
We have this configuration:
Red Hat Enterprise Linux Server release 5.3; 32 bit; VMWare Image of NagiosXI; No special configurations.Using Mozilla Firefox3.6.8.

We are trying to use WebTransaction Plugin following the testcases from the manual How to monitor web sites with XI, but after creating a new valid account and replacing the values for USER and PASS; none test past succesfully. Below I pasted both files used: config.xml and testdata.xml.

1. Are you sure your XI server can access O'Reilly's web site?
2. Do you have all of the necessary Perl libraries installed?
3. That example is known not to work if you have an ampersand (&) in your password.

(I just confirmed that it works for me here still.)

Ok Thanks tony.
So I will dismiss the internet test.
Basically I am using that example as template for monitoring our Intranet sites that requires user login checks. We have several services already monitored, but I tried adjusting the example for my needs:

Is necessary to install more modules in XI? Where is the list of modules to install in XI.

What I do not realize is the message: Use of uninitialized value in substitution (s///) at ./webinject.pl line 1161.

To be honest, I need HELP

Has anybody tested webinject with WRONG password?

it keeps me displaying TEST CASE PASSED and this is really annoying.....

Hello,
I will check a few things here and see what we can do to help resolve this for you.

Thank you.

I'm really not sure. I'm afraid my experience with WebInject is limited to putting together those example testcases just for the documentation. It appears though that this sort of error is a result of failing to find the string for verification, and then of course failing when it tries to use that in a substitution later. A good place to start would be changing the output format from 'nagios' to I think 'standard', which will let you look through the raw HTTP responses and documents to manually look at the pages and headers coming back to see if they are what you think they should be. We can keep mulling this over, but there is also a WebInject user forum that will probably be able to give you a better answer if you'd be willing to give that a shot - http://www.webinject.org/cgi-bin/forums ... oard=Users.

What we did at our company is we started using Mechanize instead of WebInject. It is easier to understand and modify.
http://search.cpan.org/~petdance/WWW-Me ... chanize.pm

We started trying to use WebInject and realized there was very little documentation to help us through issues.

Thank you for the tip nebias
