If you want to save request logging to mongodb, this is the fields description, which you will used to create a mongoose schema:

hostnameStringThe domain of current server.
original_urlStringThe original url contains query string.
pathStringThe request path doesn't contain query string.
user_agentStringThe user agent.
custom_headersObjectThe specific you wanna save.
methodStringThe http request method.
ipStringThe client's ip.
hostStringThe server's ip.
durationNumberThe millisecond the request costed.
pidNumberThe server's process id.
req_idNumberThe inner request number, auto increased when new request come.
content_length_reqNumberThe content-length of the request headers.
content_lengthNumberThe content-length of the response headers.
status_codeNumberThe status code of current HTTP response.
res_codeNumberThe inner response code, which will be got from the response header of res-code.
res_dataObjectThe reponse data.
req_timeNumberThe timestamp of begin time of current request occured.
req_time_stringStringThe time of begin time, formated in ISO 8601 Extended Format.
req_dataObjectThe request data, which would form query string or form data.
refererStringThe HTTP referer header.
sessionObjectThe session of current request.
abortedBooleanWhether the request has aborted.

We suggest you use such mongoose schema, which is compatible when the fields is changed:

const {Schema} = require('mongoose');

const requestLogSchema =  new Schema({
    req_time: Date
    timestamps: {
        createdAt: 'created_at',
        updatedAt : 'updated_at'
    strict: false
module.exports = requestLogSchema;
