xml or webpage monitor

Posted: Tue Feb 08, 2022 7:31 pm

I'm trying to set up a monitor to check if a data point is incrementing and am not sure what would be the best option or how to achieve it. I can check a webpage, which gives me an ID or timestamp that I could check, or I could check the latest timestamp in an xml file. I only need to check it a few times a day.
I tried looking at setting up an xml monitor, but couldn't figure out how to even use it. The help icon after "Key" said something about working like PHP, but it's been a very long time since I've used php and I don't understand what it's telling me. Where do I get the variables from?
Maybe I could use the website monitor and do a regex to find the returned time but how do I compare it to the current time and alert if it's too old?

The XML output will determine what is required for the key, please send us the sanitized XML output from the web page so that we can see what is being returned and that will help us guide you further.

Thank you!

Here's the xml and the html. Not sure which would be easier to work with.

Thank you, I'm analyzing it and will post an update shortly.

I was hoping we could do something like this:

Code: Select all

/usr/local/nagios/libexec/check_xml.php -u 'https://127.0.0.1/nagiosxi/index2.php' -k 'channel[item[0]][pubDate]' -s "`date +"%a, %d %b %Y %T %Z"`"
Or like this:

Code: Select all

/usr/local/nagios/libexec/check_xml.php -u 'https://127.0.0.1/nagiosxi/index2.php' -k 'channel[item[0]][pubDate]' -s "`date +"%a, %d %b %Y %H:"`*""
But that won't meet the need because you're only really checking part of a string and that doesn't seem to support wildcards.

The issue is that your looking for a string in the output but you would need to convert it to a date/time in order to compare it with the current date/time.

I found this 3rd party one that might do it but I haven't personally tested it:
