Format
In the methods you will neet to discribe the Accept Header. The API request header can be any the following:
text/plain
,text/html
,*/*
request logs in text format, ending with\n
.application/json
request logs in JSON format.text/event-stream
request logs in Server-Sent-Events format.
Stream
You can get a readble Stream object from any end point in the Logging API
dcosLogging.range.get(null, 'text/event-stream', true)
.then((stream) => {
// Forces the stream to receive a String instead of a Buffer object
stream.setEncoding('utf-8');
// Event that receives data from DCOS
stream.on('data', (chunk) => {
// Printing the chunk received from the stream
console.log(chunk);
});
// Last chunk, it runs when the connection is closed
stream.on('end', () => {
// Here you do what you need when it ends...
});
// If for some reason we receive an error while connected, we can handle it here
stream.on('errror', (err) => {
// Error handling...
})
}).catch((err) => console.log(err));
