Need Help - Can Nagios follow a "Meta refresh" redirect?

We have a new app that is hadling our web pages in HTML5. I have always monitored the site using check_http. With the latest release of the app that we use, there is a "meta refresh" that is causing check_http to fail. I have tried using the "-f follow" to no success. Anyone tell me how to do this? I cannot monitor these sites, and it is a pretty critical issue for us.

Here is the command we use - masking out sensitive data.

./check_http -H 172.xx.xxx.xxx -v -u /ws/oturl/get?apiKey=-xxxxxxxxxxx -s "/oturl.html?key="

Here is the verbose output following the above command:

http://172.xxx.xxx.xxx:80/ws/oturl/get? ... xxxxxxxxxx is 507 characters

Any help, especially quick help, would be incredibly appreciated.

Thanks

What version of check_http are you using?

Check with this command -

Code: Select all

./check_http -V

I don't believe this will be possible. check_http doesn't have an HTML or a JavaScript engine built in, so it has no concept of what either of those do. Since the refresh is within an HTML element as opposed to an HTTP header, check_http has no way of knowing what the element does, or even is.

You might have more luck with WebInject: https://github.com/sni/Webinject

But it is not our project so any support we could offer would be based solely on our own experiences with it.
