Hello Nagios XI

Ability of checking for web transactions is very important to us. When following standard WebInject documentation and samples, provided for your plugin, we re can't make most of the things work.
What to do next? Is there other tools to use with Nagios? Other plugins to use with Nagios?

Thank you

Asking "what to do next" is like asking a car dealer what to do once you've purchased a car. You can do whatever you want that the tool is programmed to do.

This is not helping: we cannot get webinject to work for our portals. (this make the entire XI solution unnecessary)

Nagios is a framework with plugins that provide most of the check logic. There are literally thousands of plugins on the Nagios Exchange (https://exchange.nagios.org/). You will need to be more specific about what you want to do with Nagios before anyone will be able to help you with specific advice on how to accomplish it.

For instance, you have opened three tickets about trying to get information from an authenticated web page. Did you look through webinject documentation and are you saying that it will not do what you want? Unfortunately, if you need Nagios to enter data into a form field on your web page in order to get past security and/or enter data that needs to be validated, you will likely not be able to do it. Nagios is a monitoring tool, not a QA/testing tool. The only way you will be able to do this sort of thing is if you can create a URL with GET paramaters in it (or write a custom plugin using curl and POST data) that contains the form data that gets passed to the authentication page.

Another option is to provide a secret, perhaps HTTP Authenticated web page that bypasses your SSO so that your monitoring system can verify functionality without having to log in. Perhaps protect it so that only the IP address of your Nagios server can access the page.

There are options, we just need to know what you are trying to do to help you figure them out.

Thank you (wish I could talk to someone from you team)

We've got Dozens of internal portals (All different) I was told to create web-transaction monitoring for (1) before-login-check / (2) login-check (3) after-login-check (4) other-operations-after-login-check and so on
- SSO no going to work with XI (from your answer)
- functionality w/o authentication (an issue is that we have to monitor "real user experience" from different angles. So this would be "yes" for functionality, but "no" for realtime monitoring of the working portals we need.

Many tickets opened: because I do not entirely understand what could or could not be done (or how). 2 traning taken with Mike Weber did not not really concentrate on WebInject or similar solutions.

I recall seeing that you were using NTLM authentication on your pages that you're trying to check, is this the case for all of them? Can you post the output of a curl <page> -v? (replace <page> with the page you're looking to check)

This plugin might work for NTLM, but there really isn't much documentation provided with it.

You'll need to try and use that plugin, or write your own with NTLM support. The plugin doesn't mention that it doesn't work, just that there is a lack of documentation. The key to your redirected output is this line - Normal webinject isn't going to work with that in mind.

This worked with NTLM-enabled Webinject and we were able to reproduce or results

Please close this case
