h1(#channels_statistic). Channel Statistics Configuration
h2(#push_stream_channels_statistics). push_stream_channels_statistics <a name="push_stream_channels_statistics" href="#">&nbsp;</a>
*syntax:* _push_stream_channels_statistics_
*context:* _location_
*release version:* _0.2.0_
Defines a location as a source of statistics. You can use this location to get statistics about a specific, group or all channels, in a resumed ou summarized way.
To get statistics about all channels in a summarized way you have to make a GET in this location without specify a name in the push_stream_channel_id variable.
To get statistics about all channels in a detailed way you have to specify "ALL" in the push_stream_channel_id.
To get statistics about prefixed channels in a detailed way you have to specify "_prefix_*" in the push_stream_channel_id.
To get statistics about a channel you have to specify the name in the push_stream_channel_id.
You can get statistics in the formats plain, xml, yaml and json. The default is json, to change this behavior you can use *Accept* header parameter passing values like "text/plain", "application/xml", "application/yaml" and "application/json" respectivelly.
<pre>
location /channels-stats {
push_stream_channels_statistics;
set $push_stream_channel_id $arg_id;
}
# /channels-stats -> get statistics about all channels in a summarized way
# /channels-stats?id=ALL -> get statistics about all channels in a detailed way
# /channels-stats?id=channel_* -> get statistics about all channels which starts with 'channel_'
# /channels-stats?id=channel_id -> get statistics about a channel

*syntax:* _push_stream_shared_memory_size size_
*default:* _32M_
*context:* _http_
The size of the memory chunk this module will use to store published messages, channels and other shared structures.

*default:* _30 seconds_
*context:* _http_
The length of time a message or a channel will stay on garbage collection area before it is completly discarded, freeing the shared memory. The minimum length is 30 seconds to ensure that no one is using these elements.
This operation is very important to help Nginx recycle memory consumed to create messages and channels, so do not use a large time.

*syntax:* _push_stream_publisher [normal | admin]_
*default:* _normal_
*context:* _location_
Defines a location as a message publisher. Requests to a publisher location are treated as messages to be sent to subscribers.
This location supports three http methods:
GET, make possible to get statistics about the channel
POST, publish a message to the channel
DELETE, remove any existent stored messages, disconnect any subscriber, and delete the channel. Available only if _admin_ value is used in this directive.
<pre>
# normal publisher location
location /pub {
push_stream_publisher;
set $push_stream_channel_id $arg_id;
}
# GET /pub?id=channel_id -> get statistics about a channel
# POST /pub?id=channel_id -> publish a message to the channel
# admin publisher location
location /pub_admin {
push_stream_publisher admin;
set $push_stream_channel_id $arg_id;
}
# GET /pub_admin?id=channel_id -> get statistics about a channel
# POST /pub_admin?id=channel_id -> publish a message to the channel

*This example uses the PushStream class present in _misc/js/pushstream.js_ file, copy it to your server htdocs.*
Configure your server like suggested bellow. You should complete this configuration with other directives according with target application.
Create a html page with the content on **Client** part, access it from browser and try with the command *curl http://localhost/pub?id=ch1 -d =="Some Text"==* .

** rake >= 0.8.7
* Required gems
** POpen4 >= 0.1.4
** em-http-request >= 0.2.14
** json >= 1.4.3
** ruby-debug >= 0.10.4
** jasmine >= 1.0.2.1
** nokogiri >= 1.5.0
** jshint >= 0.1.1
You can install these gems with bundler (bundler is required to be installed before, _gem install bundler_)
<pre>
cd test/
bundle install --without docs
</pre>
or individually
<pre>
gem install POpen4 -v 0.1.4
gem install em-http-request -v 0.2.14
gem install json -v 1.4.3
gem install ruby-debug -v 0.10.4
gem install jasmine -v 1.0.2.1
gem install nokogiri -v 1.5.0
gem install jshint -v 0.1.1
</pre>
Then issue @rake tests@.
This command run the tests using nginx *executable* located at _/usr/local/nginx/sbin/nginx_ with _1_ *worker* responding at *host* _localhost_ and *port* _9990_.
To change this behavior use the commands bellow
<pre>
rake tests executable="../build/nginx-1.1.15/objs/nginx" # to change default path for nginx executable
rake tests host=my_machine # to change default hostname
rake tests port=9889 # to change default port
rake tests workers=2 # to change dafault number of workers used
and can combine any of these parameters, like:
rake tests port=9889 executable="../build/nginx-1.1.15/objs/nginx"

*values:* _channel id_
*location:* _push_stream_publisher, push_stream_channels_statistics_
A string to uniquely identify a communication channel. Must be present on location of the push_stream_publisher and push_stream_channels_statistics.
<pre>
set $push_channel_id $arg_id;
#channel id is now the url query string parameter "id"
#(/pub?id=channel_id_string or /channels-stats?id=channel_id_string)
</pre>
h2(#push_stream_channels_path). push_stream_channels_path <a name="push_stream_channels_path" href="#">&nbsp;</a>
*values:* _set of channels id and backtrack desired messages_
*location:* _push_stream_subscriber_
A string representing a set of channels id and backtrack desired messages separated by slash, example _/channel1.b3/channel2.b5/channel3.b2_.
The backtrack means the amount of old messages from each of the channels that will be delivered to the subscriber. On the example will be 3 messages from channel1, 5 from channel2 and 2 from channel3.
Backtrack isn't needed, you can only sign channels without get old messages, or you can mix things.
More accepted examples: _/channel1_ , _/channel1/channel2_ , _/channel1.b5/channel2_ , _/channel1/channel2.b6_ , ...
Must be present on location of the push_stream_subscriber.
<pre>
location /sub/(.*) {
set $push_stream_channels_path $1;
}
#channels path is now part of url
#(/sub/channel_id_string or /sub/channel_id_string.b2/other_channel)
</pre>
