web monitoring with regex

[millerlu]

I am trying to setup web monitoring where I need to capture the value of the output in step 1 to use in step 2. It looks like I can do that with regex and have it set a variable but I am having problems making it work.
When I test this via curl my part of my output looks like this:
ms":[{"accessId":"d8b9b11e-bc8c-4a81-b7c0-5ca345c9fe0b","exp
That access ID is what I want to capture to a variable.
I tried doing something like this:
{accessId} = regex:name="accessId" content="(accessId":"(.*)",))"

But Zabbix says it can't extract the value of accessId from the output. What do I need to do in order to get this to match?
Thanks,
Luke

The web monitoring documentation could definitely use additional examples for how to capture page contents in various formats. The real-world example is a great start, but leaves unanswered questions for many, I think.

Do either of these regexes work to capture the part you want?

regex:"accessId":"([^"]+)"

regex:name="accessId" content="([^"]+)"

I got it working with this:

regex:accessId":"([0-9a-z-]+)

I agree that more examples would be helpful. I was thinking I needed the name and content parts when I really don't.

Thanks,
