getLogs

// getLogs(conditions [,stack])

let tab = syslog.getLogs({

loadStack

Load stack (json string or array) in syslog engine if doEvent is true the engine fire all events filters , before condition is a hook who can call before events fire

 // loadStack(stack [,doEvent = false, beforeConditions = null])

const syslog = new nodefony.syslog(settingsSyslog);
for (let i = 0; i < 10; i++) {
  if (i % 2) {
    syslog.log(new Error("my Error"), "ERROR");
  } else {
    syslog.log(new Error("my Critic Error"), "CRITIC");
  }
}
const json = syslog.logToJson({
  severity: {
    data: "CRITIC"
  }
});

// load syslog stack in syslog2
const syslog2 = new nodefony.syslog(settingsSyslog);

syslog2.loadStack(json, true, (pdu, ele) => {
  // you can change pdu before fire events
});

Use Syslog in nodefony services :

const nodefony = require("nodefony");

class myService extends nodefony.Service {

  constructor(name) {
    super(name);
    this.initSyslog();
    this.myMethod();
  }
  async myMethod() {
    let ret = await this.myMethod2();
    

this.log(ret);

return ret; } myMethod2() { return new Promise((resolve, reject) => { try { setTimeout(() => {

this.log("setTimeout", "WARNING");

resolve("Hello World"); }, 1000); } catch (e) { this.log(e, "ERROR"); return reject(e); } }); } } const service = new myService("hello"); /* Tue Apr 02 2019 14:58:28 WARNING SERVICE hello : setTimeout Tue Apr 02 2019 14:58:28 INFO SERVICE hello : Hello World */
