Update by zabbix support:
**********************
after comment from cyclone below conclusion is that in frontend, in web check settings, field name "required string" is misleading, as it's actually regexp.
Suggested to rename it in a way that it will be clean that it's a regexp, for example "required pattern"
Issue summary updated accordingly.
*********************
Steps to reproduce:
- Create a web scenario step (for the Jenkins login page)
- add the "required string" of "<title>Sign in [Jenkins]</title>"
Result:
See log excerpt:

Expected:
I expect that required string to be found as visible in the log and therefor the check to be successful.
I checked with a diff (just to make sure) but the required string is definitely in there.
In the log excerpt above are line feeds because I copied it from the console. The original source of the page looks as follows:
