Node.js performance statistics emitter
npm install --save stats-beat
Note: requires node v4 or higher.
const statsBeat = require('stats-beat')();
var app = express();
//...
var server = app.listen(PORT);
statsBeat.start({ server });
export STATS_BEAT=all
npm start
Then all performance metrics will be prtinted on the console each 5 seconds
{"sysload%":18,"freememMB":3661,"cpu%":112,"rssMB":152,"heapMB":64,"rps":3149,"resTime_ms":20.887753158529616,"reqBytes":116,"resBytes":114849,"rxKBs":365,"txKBs":361653,"numconn":80,"evloop_us":6646}
To report only CPU and memory ech 2s, use this command:
export STATS_BEAT='period=2&cpu&rss'
npm start
You can register a listener to process the performance metrics in a custom way, e.g. write them in a csv file or send them to a central service.
const statsBeat = require('stats-beat')();
var app = express();
//...
var server = app.listen(PORT);
statsBeat.start({ server });
statsBeat.on('stats', (stats) => {
// process stats
});
