Using

const config = {
    logRoot: require('path').resolve(__dirname, './logs'), // 日志根目录(需根据实际情况设置)
    logLevel: 'info', // file
    logLevel4console: 'error', // console

elk logstash suport

在测试环境配置logstash, 启用logstash收集日志 enableLogstash4console: true; 查看日志的地址elk

const name = 'cw-api-gateway'; // 根据实际情况可定义为项目名称
const config = {
    logRoot: require('path').resolve(__dirname, './logs'), // 日志根目录(需根据实际情况设置)
    logLevel: 'info', // file
    logLevel4console: 'error', // console
    bunyan: {
        // 级别分别是: TRACE DEBUG INFO WARN ERROR FATAL
        categorys: [{
                name: 'console',
                type: 'console',
                logLevel4console: 'error',
                pretty: true, // 格式化console输出日志, 方便查看
                src: true
            },{
                name: 'app', // 模块/分类
                type: 'rotatingFile',
                pretty: true, // 格式化console输出日志, 方便查看
                src: false,
                // logLevel: 'info',
                // logLevel4console: 'error',
                rotateConfig: {
                    period: '1d', // The period at which to rotate.
                    threshold: '10m', // Rotate log files larger than 10 megabytes
                    totalFiles: 10 //The maximum number of rotated files to keep. 0 to keep files regardless of how many there are.
                }
            },{
                name: 'login', // 模块/分类
                type: 'rotatingFile',
                pretty: true, // 格式化console输出日志, 方便查看
                // logLevel: 'info',
                // logLevel4console: 'error',
                rotateConfig: {
                    period: '1d', // The period at which to rotate.
                    threshold: '10m', // Rotate log files larger than 10 megabytes
                    totalFiles: 0 //The maximum number of rotated files to keep. 0 to keep files regardless of how many there are.
                }
            }
        ]
    },
    enableLogstash4console: true, // 使用elk收集日志
    currentLogstashInput: 'tcp', // tcp数据包(相比udp, 大小默认无限制)
    logstash: {
        type: name + (process.env.SITE_DOMAIN ? `-${process.env.SITE_DOMAIN}` : ''),
        udp: {
            host: '192.168.2.155',
            port: 64100,
          type: name + (process.env.SITE_DOMAIN ? `-${process.env.SITE_DOMAIN}` : '')
        },
        tcp: {
            host: '192.168.2.155',
            port: 64756,
          type: name + (process.env.SITE_DOMAIN ? `-${process.env.SITE_DOMAIN}` : '')
        }
    },
}

stdout suport pretty format

// 不保证性能, 建议只在开发环境开启pretty, 在生产环境关闭(或者设置logLevel4console为error以上)
// 设置pretty
{
    pretty: true // 格式化console输出日志, 方便查看
}
