        isOutputToFile?: boolean; //default: true
        logOutputFile?: string; //default: logs/[Date].log  placeholders: [Date] [Hour] [Minute]
    },
    checkSystemMSec ?: number; //check system status(cpu sec and memory usage) per ms, default: 25
    //save records to log default 200ms, 8 times of checkSystemMSec, if no warnings
    collection?: { //record requests and system status
        outputPath ?: string; //default: 'null'
    }
    ban?: { //[not realize currently]
        ip?: Array<string | RegExp>;
        cookie?: Array<string | RegExp>;
        token?: Array<string | RegExp>;
    },
    rules?: {
        //[not realize currently]
        ban?: {
            ip?: Array<number>;
            cookie?: Array<number>;
            token?: Array<number>;
        },
    },
    warnings?: {
        cpu?: string; // ex. 5%
        usingMemory?: string | number; // ex. 5% or 1048576 (Bytes)
        freeMemory?: string | number; // ex. 5% or 1048576 (Bytes)
        websiteQps?: number; //[not realize currently]
        endpointQps?: number; //[not realize currently]
        outputPath?: string; //default: warnings.log
    }
};

?: Means optional ?:表示可选

Methods: 方法：

• logger Logger system 日志系统

logger has an constructor
You can use const log = new logger('name'); to create a new logger
There are several different levels in logger, sorted by lower

• TRACE
• DEBUG
• INFO
• WARN
• ERROR
• FATAL

Default output level is INFO, you can set level to DEBUG by log.filter = logger.DEBUG
examples:

const monitor = require('endpoint-monitor');
const log = new monitor.logger('Test');
log.info('Endpoint Monitor');
//output: [2022-08-24T21:54:24.896Z] [INFO] Test - Endpoint Monitor

We hooked the HTTP Server, and added monitoring for requests and responses. 我们对HTTP服务器做了钩子，增加了对请求和响应的监控
You can use const http = monitor.http instead of const http = require('http'); 你可以使用const http = monitor.http; 来代替 const http = require('http');
API is all the same. 应用程序接口是全部一样的。

It only supports native http server so far. 目前仅支持的原生http服务器的支持
~~It will add supports for express in the near future. 将来会增加对express框架的支持~~
Support for express: Endpoint-Monitor-Express
