Work Description: GitHub user jrushford opened a pull request:
https://github.com/apache/trafficserver/pull/1258
TS-5089: Add money_trace plugin.
This is an experimental remap plugin that is now open sourced that allows
traffic server caches to participate in a distributed tracing system that
utilizes the Comcast Money library. The Comcast Money library,
https://github.com/Comcast/money/wiki, has its roots in Google Dapper and
Twitter's zipkin.
Hopefully this plugin may prove useful for others in the community.

> This is an experimental remap plugin that allows ATS to participate in a
> distrbuted tracing system based upon the Comcast "Money" distributed tracing
> and monitoring library. The Comcast "Money" library has its roots in
> Google's Dapper and Twitters Zipkin systems. A money trace header or session
> id, is attached to transaction and allows an operator with the appropriate
> logging systems in place, to determine where errors and/or latency may exit.
> Use of the library enables the tracing of a transaction through all systems
> that participate in handling the request. See the documentation on this open
> source library at https://github.com/Comcast/money/wiki.
> This plugin checks incoming requests for the "X-MoneyTrace" header. If the
> header is not present no further processing takes place. However if the
> header is present, the plugin will check to to see if the request has been
> cached. If so, the plugin will add the "X-Moneytrace" header from the
> incoming request to the cached response returned to the client as required by
> the money_trace protocol. If the request has not been cached, the plugin
> will extends the trace context by creating a new "X-MoneyTrace" header for
> inclusion in the outgoing request to a parent cache or origin server. The
> extended header includes the 'trace-id' from the incoming request, the
> incoming span-id becomes the outgoing parent-id and the plugin generates a
> new random long span id for the outgoing request. See the documentation at
> the link above for a complete description on the "X-MoneyTrace" header and
> how to use and extend it in a distributed tracing system.
> To configure and use this plugin, simply add it in the remap.config file
> where needed. EXAMPLE:
> map http://vod.foobar.com http://origin.vod.foobar.com
> @plugin=money_trace.so
