The web-scenario-based monitoring we just set up is quite powerful, but there might be cases where a more simple approach would be enough. On the agent level, there are some interesting item keys that allow us to retrieve web pages and perform simple verification. An additional benefit is the ability to do that from any agent, so it is very easy to check web page availability from multiple geographically-distributed locations. There are three web page-related item keys:
- web.page.get
- web.page.perf
- web.page.regexp
Also keep in mind the simpler item keys, such as net.tcp.service, which was discussed in Chapter 3, Monitoring with Zabbix Agents and Basic Protocols.
