What type of information can be monitored using "web scenarios" in Zabbix?

Web scenarios in Zabbix are specifically designed to monitor the performance and availability of websites. By creating web scenarios, users can define sequences of steps that replicate a user's interaction with a web page, allowing for thorough testing of the site's functionality and response times. This includes monitoring whether a website is reachable, how quickly it responds, and whether it loads correctly under various conditions.

Monitoring the overall health of a website using web scenarios enables administrators to ensure that critical web applications are available and performing optimally. This proactive approach helps identify potential issues before they impact end users. Functions captured in web scenarios include checking specific URLs, examining response codes, measuring load times, and confirming the presence of particular content on the page.

While user login activity, server load and CPU utilization, and network bandwidth and latency are all critical aspects of IT monitoring, they are not the primary focus of web scenarios within Zabbix. Instead, these functionalities are tracked using other items and methods in Zabbix, making option A the definitive choice for what web scenarios encompass.
