Is there any way to verify the content of pdf file in the step of Zabbix web scenario?
I need to compare text in pdf with variable from the previous step.
No, you can use the Required string parameter with HTML content only and with some limitations, from the documentation:
Required regular expression pattern. Unless retrieved content (HTML) matches the required pattern the step will fail. If empty, no check on required string is performed. For example: Homepage of Zabbix Welcome.*admin Note: Referencing regular expressions created in the Zabbix frontend is not supported in this field.
The behavior, based on libcurl, is almost the same with the native http agent, I think that you have to use an external script to download, parse/render and extract text from the pdf.
