Varnish Administration Console
It is a requirement that Varnish agent has to be installed on the same server as Varnish Cache itself. This is mandatory for establishing the communication between VAC and Varnish Cache through the RESTful interface provided by Varnish-agent.
Varnish-agent utilizes both Varnish CLI and Varnish API directly as the key mechanism for accessing the internals of Varnish Cache. Therefore it is recommended that the following parameters are set on Varnish to mitigate large amounts of redundant CLI traffic being written to syslog. See below
syslog_cli_traffic=off
The previously mentioned parameters can be changed through VAC or via Varnish startup script.
The pre-made packages for the Varnish-agent are available in the Varnish Plus Software repository.
