Another web page-related agent item is web.page.perf. It returns the loading time of the page in seconds. While still in the item list, click on Create item, and fill in the following:

• Name: Zabbix main page load time
• Key: web.page.perf[127.0.0.1,/zabbix/index.php]
• Type of information: Numeric (float)
• Units: s
• Applications: ZABBIX

When you've done that click on the Add button at the bottom. We changed Type of information, as this item key returns the time it took to load the page in seconds, and that value will usually consist of a decimal part.
