Usage

npm install pm2-describe --save

Before use pm2-describe, you must be conntected with pm2.

basic usage:

const pm2Desc = require('pm2-describe');                    
const pm2 = require('pm2');                            
                                                       
pm2Desc(pm2, {                                         
    interval: 2000                                     
});                                                    
                                                       
pm2.connect(err => {                                   
    if (err) {                                         
        console.log(err);                              
    }                                                  
                                                       
    pm2                                                
    .onDescribe(function(list) {                       
        console.log(list); 
    })                                                 
    .descError(function(err) {                         
        console.log('Error: ', err);       
    })                                       
    .descStart();                                
});

more example:

const pm2Desc = require('pm2-describe');
const pm2 = require('pm2');

let log = function () {
    console.log(new Date().getMinutes() + ":" + new Date().getSeconds(), arguments[0]);
};

pm2Desc(pm2, {
    interval: 2000
});

pm2.connect(err => {
    if (err) {
        log(err);
    }

    pm2
    .onDescribe(function(list) {
        log('Count Processes: '+ list.length);
    })
    .descError(function(err) {
        log('Error: '+ err);
    })
    .descStart();

    setTimeout(function() {
        log('Clear describe !');
        pm2.descClear();
    }, 4000);

    setTimeout(function() {
        log('Start it again !');
        pm2.descStart();
    }, 7000);

    setTimeout(function() {
        log('Change onDescribe callback !');
        pm2.onDescribe(function(list) {
            log('One pm id: '+ list[0].pm_id);
        });
    }, 11000);

    setTimeout(function() {
        log('Reset my interval !');
        pm2.resetDescInterval(500);
    }, 14000);

    setTimeout(function() {
        log('Clear describe !');
        pm2.descClear();
        log('The End');
    }, 17000);
});

output:

4:33 Count Processes: 5
4:35 Clear describe !
4:38 Start it again !
4:40 Count Processes: 5
4:42 Change onDescribe callback !
4:42 One pm id: 0
4:44 One pm id: 0
4:45 Reset my interval !
4:45 One pm id: 0
4:46 One pm id: 0
4:46 One pm id: 0
4:47 One pm id: 0
4:47 One pm id: 0
4:48 Clear describe !
4:48 The End

Init

const pm2Desc = require('pm2-describe');
const pm2 = require('pm2');

pm2Desc(pm2, {     
    interval: 2000 
});                
  • pm2: pm2 module, required
  • options
  • interval: Number, unit ms, default 2000, optional

API

Extend API of PM2 :

  • onDescribe(callback) describe callback
  • descStart(interval) interval: Number, optional. start describe task
  • descClear() clear describe task
  • resetDescInterval(interval) interval: Number, required. change interval and restart task
  • descError(callback) errors

Outputs

onDescribe callback list should like this:
