Tracing with Jaeger

There is a tracing filter, by which we can add tracing function for pixiu

http_filters:
- name: dgp.filters.tracing
 config:
 url: http://127.0.0.1:14268/api/traces
 type: jaeger

you can quick start the demo in samples/dubbogo/simple/jaeger for experience

Prometheus

Mon, 01 Jan 0001 00:00:00 +0000

Metric Filter Quick Start

Start PrometheusPushGateway [Docker environment]:

Use Docker to install and start：

Directly obtain the latest version of the official image prom/pushgateway:latest The startup command is as follows:

$ docker pull prom/pushgateway

$ docker run -d -p 9091:9091 prom/pushgateway

Use the command ./pushgateway command to start the service. At this time, the browser can access the UI page by accessing http://<ip>:9091, but there is no data display on the default Metrics, that is because we have not yet sent to PushGateway Push any data.
