Log


INTRODUCTION

This component allows you to record what happens in the system. The plugin has an operation similar to the plugin for sending emails but instead of sending a message, it is logged to a file that can be viewed later.

USE CASES

  • This kind of component allow you to control a specific behaviour of a specific component.
  • This component comes useful if a user need to take track of specific information that needs to be exported such as energy consumption and power production or just keeping track of the temperature coming from a probe or sensor.

Inside the content text field add this text “##IDOFTHECOMPONENTTOLOG##”, with this procedure you are allowed to add as much components as you need.

Remember to use the comma, at the end of every information, that will divide and format your text in the right way inside your .csv file.

Note: text field available for additional information on the component from the admin side.

CSV EXAMPLE

This is a simple example of a log that checks if a door was opened or not. As you can see it will record the change of a status of a component and the exact time when the changes happened. If you want the file to be exported in .CSV you should add the extension in the “File name” field in Eve Manager.

LOG TIME

Inside the “logs” folder inside your server, you will find that we store two logs, one daily log called “today_YOURFILENAME” and one folder with the date(YY/MM) with all the logs of the month, this will help to organize all your log files.

A reminder before continuing:

  • Download and Install EVE Logic plugin to enable plugins (link);
  • After loading .eve project to the server, wait a couple of minutes for logics activation.
