:Manual section: 3
SYNOPSIS
========
import statsd;
sub vcl_init {
# Optional, defaults to localhost:8125
statsd.server( "statsd.example.com", "8125" );
}
sub vcl_deliver {
statsd.incr( "incr" );
statsd.gauge( "gauge", 42 );
statsd.timing( "timing", 42 );
statsd.counter( "counter", 42 );
}
DESCRIPTION
===========
Varnish Module (vmod) for sending statistics to Statsd.
See https://github.com/etsy/statsd for documentation on Statsd.
FUNCTIONS
=========
server
------
Prototype::
server(STRING S, STRING S)
Return value
NONE
Description
Set the address of your Statsd server.
Best used in vcl_init. Defaults to "localhost", "8125"
Example::
statsd.server( "statsd.example.com", "8125" );
prefix
------
Prototype::
prefix(STRING S)
Return value
NONE
Description
Set a string to prefix to all the stats you will be sending.
Best used in vcl_init. Defaults to an empty string.
Example::
# statsd.incr( "foo" ) will now send "dev.foo" to Statsd
statsd.prefix( "dev." );
suffix
------
Prototype::
suffix(STRING S)
Return value
NONE
Description
Set a string to suffix to all the stats you will be sending.
Best used in vcl_init. Defaults to an empty string.
Example::
# statsd.incr( "foo" ) will now send "foo.dev" to Statsd
statsd.suffix( ".dev" );
incr
----
Prototype::
incr(STRING S)
Return value
NONE
Description
Send a stat counter with value '1' to Statsd. Will be prefixed & suffixed
with whatever you set statsd.prefix & statsd.suffix to.
Example::
statsd.incr( "foo" );
counter
-------
Prototype::
counter(STRING S, INT I)
Return value
NONE
Description
Send a stat counter with value I to Statsd. Will be prefixed & suffixed
with whatever you set statsd.prefix & statsd.suffix to.
Example::
statsd.counter( "foo", 42 );
timing
-------
Prototype::
timing(STRING S, INT I)
Return value
NONE
Description
Send a stat timer with value I to Statsd. Will be prefixed & suffixed
with whatever you set statsd.prefix & statsd.suffix to.
Example::
statsd.timing( "foo", 42 );
gauge
-----
Prototype::
gauge(STRING S, INT I)
Return value
NONE
Description
Send a stat gauge with value I to Statsd. Will be prefixed & suffixed
with whatever you set statsd.prefix & statsd.suffix to.
Example::
statsd.gauge( "foo", 42 );
INSTALLATION
============
To install this module, you'll need to install some prerequisites. On Ubuntu,
you can get these by running::
$ apt-get install automake libtool python-docutils libvarnishapi-dev make
You will also need a compiled version of the varnish source code, which you
can get from here:
https://www.varnish-cache.org
The compilation of varnish is similar to this package. Please refer to the
varnish documentation for all the options, but briefly, it is::
$ ./autogen.sh
$ ./configure
$ make
If you received this packge without a pre-generated configure script, you will
have to generate it using 'autogen.sh'. Otherwise, you can move straight on to
the 'configure' section under Usage.
Usage::
# Generate configure script
./autogen.sh
# Execute configure script
./configure VARNISHSRC=DIR [VMODDIR=DIR]
`VARNISHSRC` is the directory of the Varnish source tree for which to
compile your vmod. Both the `VARNISHSRC` and `VARNISHSRC/include`
will be added to the include search paths for your module.
Optionally you can also set the vmod install directory by adding
`VMODDIR=DIR` (defaults to the pkg-config discovered directory from your
Varnish installation).
Make targets:
* make - builds the vmod
* make install - installs your vmod in `VMODDIR`
* make check - runs the unit tests in ``src/tests/*.vtc``
