Peculiarities

There are a couple of things that are different with Vinyl Cache, as opposed to other programs. One thing you’ve already seen - VCL. In this section we provide a very quick tour of other peculiarities you need to know about to get the most out of Vinyl Cache.

Configuration

The vinyld Configuration is written in VCL. When vinyld is run this configuration is transformed into C code and then fed into a C compiler, loaded and executed.

So, as opposed to switching various settings on or off, you write polices on how the incoming traffic should be handled.

vinyladm

Vinyl Cache has an admin console. You can connect it through the vinyladm command. In order to connect the user needs to be able to read /etc/vinyl-cache/secret in order to authenticate.

Once you’ve started the console you can do quite a few operations on vinyld, like stopping and starting the cache process, load VCL, adjust the built in load balancer and invalidate cached content.

It has a built in command “help” which will give you some hints on what it does.

vinyllog

Vinyld does not log to disk. Instead it logs to a chunk of memory. It is actually streaming the logs. At any time you'll be able to connect to the stream and see what is going on. ``Vinyld logs quite a bit of information. You can have a look at the logstream with the command vinyllog.
