Get detailed error response from WebInject Nagios Plugin using XML POST

[Andrei Poltoratsky]

Hi,

I'm using WebInject as a Nagios plugin to check a web server using XML
POST. When the request fails, the plugin provides the information in
the way like 'WebInject test case x failed'. I've read the manual and
found that I can also use a custom error message, like 'It's hard to
say this, but there's an error.'

What do I need is to get a notification from Nagios which includes
server error message output. I've tried to play with postresponse and
{PARSEDRESULT}, but without success.

Here is my config file:


<case
id="1"
description1="My Description"
addheader='SOAPAction: "http://myurl/MyAction"'
logrequest="yes"
logresponse="yes"
method="post"
parseresponse='"string1"|"string2"|escape'
posttype="text/xml"
postbody="file=>myfile.xml"
url="http://myurl"
verifypositive="MYTESTMESSAGE"
errormessage = "got error: {PARSEDRESULT}"
/>

When I launch webinject.pl with this config, I receive the following
message:


-------------------------------------------------------
Use of uninitialized value in substitution (s///) at ./webinject.pl
line 1148.
Test: testcasestest.xml - 1
My Description
Verify : "MYTESTSTRING"
Passed XML Parser (content is well-formed)
Failed Positive Verification
Failed HTTP Response Code Verification (HTTP/1.1 405 Method Not
Allowed)
Use of uninitialized value $_ in substitution (s///) at ./webinject.pl
line 1161.
TEST CASE FAILED : got error:
Response Time = 0.134 sec
-------------------------------------------------------

Can someone help me with solving my problem? What I actually need is
to receive a notification from Nagios like:

CRITICAL: Error! Server returned XXX error code with a message
*messagetext*.

Thanks!

Dear Sven,

I'm using WebInject 1.41. It seems to be a latest version.

Development has moved to github and cpan. Get the latest version
from http://search.cpan.org/perldoc?Webinject or https://github.com/sni/Webinject
Latest version is the 1.72.

Oh!

Thanks a lot for the information. I'll try to get the latest version
from github and will inform about the results. Just in case if someone
will search Google for the same problem solution.

I think its better to have a seperate check for dns or http response
time and use webinject just
for end-to-end tests. Nagios offers much more possibilities than
webinject. You could even combine
these checks with the fabulous 'check_multi' plugin. So first do you
basic dns, ping, http check and
then webinject at the end.

I didn't know about check_multi. Will search Google.

Thanks, Sven!
