Technical Note : Using the diagnose wad webcache list command in FortiOS 4.3
Description
This article provides a description of how to display web caching stats by using the diagnose wad webcache list command.
Scope
FortiOS v4.3
Solution
This following command displays the web caching stats for the last 10 minutes of activity. The information displayed is divided into 20 slots and each slot contains stats for 30 seconds.
20 * 30 seconds = 600 seconds = 10 minutes.
The first 20 slots are for HTTP requests in the last 10 minutes. Each slot of stats has four numbers, which is the total number of HTTP requests, the number of cacheable HTTP requests, the number of HTTP requests that are processed by the web cache (hits), and the number of HTTP requests that are processed without checking the web cache (bypass). There are many reasons that a HTTP request may bypass web cache.
The next 20 slots are for video requests in the last 10 minutes. Each slot has two numbers for each 30 seconds: total number of video requests, and the number of video requests that are processing using cached data.
These 20 slots are for traffic details in last 10 minutes. Each slot has four numbers for 30 seconds each.
20 * 30 seconds = 600 seconds = 10 minutes.
