IMPORTANT: elasticsearch.js has been replaced by the new Elasticsearch JavaScript client. We strongly advise you to migrate to the new client. To learn more, see the migration guide.

editIn the future we may add loggers for some of the more common libraries, but for now this is an exercise for the user. Here is a hint to get you started implementing a Bunyan log class. Be sure to check out the Bunyan repo for more info about setting things up.
in log_to_bunyan.js.
module.exports = LogToBunyan;
var bunyan = require('bunyan');
function LogToBunyan(config) {
// config is the object passed to the client constructor.
var bun = bunyan.createLogger({name: 'mylogger'});
this.error = bun.error.bind(bun);
this.warning = bun.warn.bind(bun);
this.info = bun.info.bind(bun);
this.debug = bun.debug.bind(bun);
this.trace = function (method, requestUrl, body, responseBody, responseStatus) {
bun.trace({
method: method,
requestUrl: requestUrl,
body: body,
responseBody: responseBody,
responseStatus: responseStatus
});
};
this.close = function () { /* bunyan's loggers do not need to be closed */ };
}
in model.js.
var elasticsearch = require('elasticsearch');
var LogClass = require('./log_to_bunyan');
// now just pass the log class to the client constructor using the "log" config option.
var client = new elasticsearch.Client({ log: LogClass });
