Cacti Varnish Template

======================

Uses advanced template from:

Combines script to pull data via Varnish admin port from

How to install

--------------

 1. Import `cacti_host_template_varnish.xml` to Cacti

 2. Copy `get_varnish_stats.py` to `scripts`

 3. Make the varnishstat available to your Cacti machine (read below)

**IMPORTANT**: You need to recompile `spine` with `./configure --with-results-buffer=2048`.

For Varnish 2, you can use Varnish management service, configure it to be accessible. For 2.0 make sure you lock down appropriately with `iptables` or similar, because there is no authentication for this interface, for 2.1 the authentication is (currently) not implemented by this template poller.

Varnish 3 does not have `stats` command anymore in management interface. You can setup [inetd][1] daemon like [xinetd][2] to serve the `varnishstat` command remotely (again be sure to restrict access to prevent any unauthorized access):

```

service varnishstat

{

    socket_type         = stream

    wait                = no

    user                = nobody

    server              = /usr/bin/varnishstat

    server_args         = -1

    only_from          = 10.10.0.7

    log_on_success      = HOST

}

```
