CONTRIB: opentracing: add the OpenTracing filter This commit adds the OpenTracing filter (hereinafter we will use the abbreviated name 'the OT filter') to the contrib tree. The OT filter adds native support for using distributed tracing in HAProxy. This is enabled by sending an OpenTracing compliant request to one of the supported tracers; such as Datadog, Jaeger, Lightstep and Zipkin tracers. Please note: tracers are not listed by any preference, but alphabetically. The OT filter is a standard HAProxy filter, so what applies to others also applies to this one (of course, by that I mean what is described in the documentation, more precisely in the doc/internals/filters.txt file). The OT filter activation is done explicitly by specifying it in the HAProxy configuration. If this is not done, the OT filter in no way participates in the work of HAProxy. As for the impact on HAProxy speed, this is documented with several tests located in the test directory, and the result is found in the README-speed-* files. In short, the speed of operation depends on the way it is used and the complexity of the configuration, from an almost immeasurable impact to a significant deceleration (5x and more). I think that in some normal use the speed of HAProxy with the filter on will be quite satisfactory with a slowdown of less than 4%. The OT filter allows intensive use of ACLs, which can be defined anywhere in the configuration. Thus, it is possible to use the filter only for those connections that are of interest to us. More detailed documentation related to the operation, configuration and use of the filter can be found in the contrib/opentracing directory. To make the OpenTracing filter easier to configure and compile, several entries have been added to the Makefile. When running the make utility, it is possible to use several new arguments: USE_OT=1 : enable the OpenTracing filter OT_DEBUG=1 : compile the OpenTracing filter in debug mode OT_INC=path : force the include path to libopentracing-c-wrapper OT_LIB=path : force the lib path to libopentracing-c-wrapper OT_RUNPATH=1 : add libopentracing-c-wrapper RUNPATH to haproxy executable If USE_OT is set, then an additional Makefile from the contrib/opentracing directory is included in the compilation process.
