Gobench
A distributed benchmark tool with Golang
Why gobench
Targets: Supporting more than HTTP like MQTT, Websocket, graphQL. It can scale to support up to 1 million connection concurrently. It could support scriptable tool.
Workers
Supported workers: MQTT, NATs, HTTP
Please see the following section for creating a new type of worker.
Web API
Get histogram metric:
http://localhost:1234/api/metrics/55/histograms
Get histogram metric from a timestamp (ms)
http://localhost:1234/api/metrics/55/histograms?from=1586320159476&end=1586320169476

How to write a new worker
Creating a new type of worker for gobench is very simple. The worker has to have the following properties.
Expose the metrics
Exposes to gobench via gobench.Setup(groups) calling where groups is []metrics.Group{} structure.
For convience, one should call the metrics setup at the end of constructor like NewHttpClient on which calling gobench.Setup.
Gobench strickly force you to create the metrics hierarchy. Group name (Group.Name) must be unique globally. Also metric title (Metric.Title) must be unique globally.
Gobench is supporting 3 kinds of metric: counter, histogram, and gauge.
Notify the metric
Notify to gobench via gobench.Notify(metric name, value).
See workers/http for HTTP worker example.
