Answer 1

I'm using node bunyan, this is an option to debug and track queries(may help someone else)

function serializer(data) {
    let query = JSON.stringify(data.query);
    let options = JSON.stringify(data.options || {});

    return `db.${data.coll}.${data.method}(${query}, ${options});`;
}

let log = bunyan.createLogger({
    name: 'AppName',
    src: false,
    serializers: {
        // ...
        dbQuery: querySerializer
        // ...
    },
    // ...
});

mongoose.set('debug', function(coll, method, query, doc, options) {
    let set = {
        coll: coll,
        method: method,
        query: query,
        doc: doc,
        options: options
    };

    log.info({
        dbQuery: set
    });
});
