SummaryWhen dealing with edge cache, it is not possible to look at a list of files in it, but there are still ways to analyze edge cache.
OverviewThe edge cache is a tool that will cache certain types of traffic on the Exinda appliance that will then be distributed to other clients that ask for the same data from the WAN. This saves on traffic going outside of the LAN and thus will reduce fetch and load times for pages for end users. Edge cache can be configured via the web UI or the CLI in terms of black/whitelists, the minimum/maximum size of objects that should be cached, whether HTTPS should be cached, etc.
Some users might wish to check the contents of the edge cache to see the items that are located in it at any given time, whether it's to see if it is working or troubleshooting a supposed issue. However, there is no way to check the contents of the cache directly, via either the web UI or the CLI. This means that it is not possible to look at exactly what the cache is holding.
CauseThis functionality is currently not programmed into the appliance.
WorkaroundIndividual objects themselves in the edge cache cannot be listed and analyzed, but Monitoring > Real Time > Conversations will give a real time view of traffic that is being caught by the edge cache (conversations that are highlighted by the blue stripe). It will not give details about exactly what the traffic is that is being cached on an item by item basis, but it will prove that edge cache is working and will allow for seeing the type of traffic being cached (HTTP, HTTPS, domains, etc).
Furthermore, an edge cache report will show how much data is in the edge cache over a given period of time, but again, will not show the items specifically. A 'show storage edge-cache' command on the CLI will also show the state of the edge cache with respect to the physical disk that it is located on, such as how much space it is taking up.
