A collection of HTML pages to display stats and trace data and allow library configuration control
OpenCensus Zpages Exporter implements a collection of HTML pages that display stats and trace data sent from OpenCensus Node.js.
The library is in alpha stage and the API is subject to change.
npm install @opencensus/nodejs
npm install @opencensus/exporter-zpages
Zpages always runs on localhost, but you can change the port in the options. If the option startServer is set to true, Zpages server will start when a new Zpages instance is created. It's also possible to predefined some span names. These empty spans will be listed on Zpages.
To use Zpages, instance the exporter on your application and pass the options. For javascript:
const tracing = require('@opencensus/nodejs');
const zpages = require('@opencensus/exporter-zipkin');
// Add your zipkin url and application name to the Zipkin options
const options = {
port: 8080, // default
startServer: true, // default
spanNames: ['predefined/span1', 'predefined/span2']
}
const exporter = new zpages.ZpagesExporter(options);
Similarly for Typescript:
import * as tracing from '@opencensus/nodejs';
import {ZpagesExporter, ZpagesExporterOptions} from '@opencensus/zpages-exporter';
// Add your zipkin url and application name to the Zipkin options
const options: ZpagesExporterOptions = {
port: 8080, // default
startServer: true, // default
spanNames: ['predefined/span1', 'predefined/span2']
};
const exporter = new ZpagesExporter(options);
Now, register the exporter and start tracing.
tracing.start({'exporter': exporter});
or
tracing.registerExporter(exporter).start();
If options.startServer is set to false, the server can be started by calling startServer method:
zpages.startServer();
The server will run at http:\\localhost:port.
There are four pages you can browse.
/tracez: Trace list.
/traceconfigz: Trace settings.
/rpcz: RPC stats (not yet implemented).
/stats: Stats page (not yet implemented).
If it is necessary to stop the server programmatically, use the following command:
zpages.stopServer();
