I would like to explaned my solution to problem in viewer logs in pm2 monit and pm2 logs.

My logger.js

import log4js from 'log4js'

log4js.configure( {
    appenders : {
        viewerLogsInPM2 : { type : 'stdout' },
        everything : {
            type : 'dateFile',
            filename : 'logs/orchestrator.log',
            // pattern : 'yyyy-MM-dd',
            pattern : 'yyyy-MM-dd-hh-mm',
            maxLogSize : '1G',
            numBackups : 30,
            compress : false,
            keepFileExt : true,
            fileNameSep : '-',
            layout : {
                type : 'pattern',
                pattern : '%d{yyyy-MM-dd hh:mm:ss.SSS}|orchestrator|%m'
            }
        },
        errorFile : {
            type : 'dateFile',
            filename : 'logs/orchestrator-errors.log',
            // pattern : '-yyyy-MM-dd',
            pattern : 'yyyy-MM-dd-hh-mm',
            maxLogSize : '1G',
            numBackups : 60,
            compress : false,
            keepFileExt : true,
            fileNameSep : '-',
            layout : {
                type : 'pattern',
                pattern : '%d{yyyy-MM-dd hh:mm:ss.SSS}|orchestrator|%m'
            }
        },
        errors : {
            type : 'logLevelFilter',
            level : 'ERROR',
            appender : 'errorFile'
        }
    },
    categories : {
        default : { appenders : ['viewerLogsInPM2', 'everything', 'errors'], level : 'debug' },
    },
    pm2 : true,
    pm2InstanceVar : '0'
} )

const logger = log4js.getLogger()
export default logger

My ecosystem.config.js

module.exports = {
    apps : [
        {
            name : 'orchestrator',
            script : './build/src/app.js',
            watch : false,
            instance_var: 0,
            env : {
                PORT : 3000,
                NODE_ENV : 'production'
            }
        }
    ]
}

---

My logger file is generated the following files:

logs/orchestrator-errors-2022-08-24-16-05-1.log

logs/orchestrator-2022-08-24-16-05-1.log

logs/orchestrator.log (now)

logs/orchestrator-errors.log (now)

ps.: enabled pattern with 'yyyy-MM-dd-hh-mm' to test rotate, after test, enable the pattern yyyy-MM-dd for daily rotate

Friends, i would like to apologize for polluting the issue queue, but, i struggled to get this to work and maybe it will be useful for someone else =D
