Trace Server
Trace server is a distributed tracing storage system. It's built for the micro ecosystem and to be used with go-platform/trace
Getting started
Install Consul
Consul is the default registry/discovery for go-micro apps. It's however pluggable. https://www.consul.io/intro/getting-started/install.html
Run Consul
$ consul agent -server -bootstrap-expect 1 -data-dir /tmp/consulDownload and start the service
go get github.com/micro/trace-srv trace-srv --database_url="root:root@tcp(192.168.99.100:3306)/trace"OR as a docker container
docker run microhq/trace-srv --database_url="root:root@tcp(192.168.99.100:3306)/user" --registry_address=YOUR_REGISTRY_ADDRESS
The Trace API

}Sending to Trace
The trace server consumes messages from the broker topic micro.trace.span. Traces can be generated and sent with the go-platform.
