Issue Time Tracking ------------------- Worklog Id: (was: 33784) Time Spent: 1h 40m (was: 1.5h) > Add money_trace plugin > ---------------------- > > Key: TS-5089 > URL: https://issues.apache.org/jira/browse/TS-5089 > Project: Traffic Server > Issue Type: New Feature > Components: Plugins > Reporter: John Rushford > Priority: Minor > Fix For: sometime > > Time Spent: 1h 40m > Remaining Estimate: 0h > > 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.
