Microservices observability and logging, heavily inspired by Google's Dapper paper and Twitter's Zipkin implementation.

Client links:

[{ name: "log message", spanId: "string", severity: "string ('debug'|'info'|'warning'|'error')", message: "string", stackTrace: "string (for error/exceptions)" }, { name: "client start" url: "/client/start", actions: ["POST"], body: { traceId: "string", spanId: "string", parentSpanId: "string", ipAddress: "string", requestUrl: "string", requestParameters: [{key: string, value: string}] }, }, { name: "client end" url: "/client/end", actions: ["POST"], body: { traceId: "string", spanId: "string", parentSpanId: "string", }, }, { name: "remote call start" url: "/remote-call/start", actions: ["POST"], body: { traceId: "string", spanId: "string", parentSpanId: "string", }, }, { name: "remote call end" url: "/remote-call/end", actions: ["POST"], body: { traceId: "string", spanId: "string", parentSpanId: "string", responseCode: "http status code" }, }]

Server Urls: [{ name: "most recent", actions: ["GET"], template: "/recent/{count}", }, { name: "most recent by ip", actions: ["GET"], template: "/recent-by-ip/{ip-address}/{count}", }]

Note: most recent should return: { traces: [{ url: "/trace/1", ip: "127.0.0.1", start: "2016-02-06T20:37:47Z", end: "2016-02-06T20:37:58Z" }, { url: "/trace/2", ip: "127.0.0.1", start: "2016-02-06T20:35:02Z", end: "2016-02-06T20:35:28Z" }], links: [{ name: "next", url: "/recent/10/offset/20", }(optional: , { name: "previous", url: "/recent/10/offset/0", })] }]

Trace returns: { traceId: "string", start: "2016-02-06T20:35:02Z", end: "2016-02-06T20:35:28Z", spans: [{ }]

}

Queries - use original call for info

• 10 most recent
• 10 most recent filtered by ip/name
• Index listingget traceid, ip/name, function called

Access by TraceId

• Retreive trace data and all span data
