I'm new to Zabbix and I have some troubles with setting up login monitoring on our site. The issue is that our login form contains some hidden input field called 'lt' with randomly generated string that needs to be submitted along with user data to login successfully. Question is how can I parse page to get the generated value from page and use it to submit form along with traditional login/password.
You have to use variable, which will be defined by regexp. For example:
{lt}=regex:"lt":"(.+)"
Then you can use lt variable in next step of your web scenario.
