CodeIgniter Error Log Info + Errors

Question

IS there a way to save in the log, Info + Errors without debug?
Howcome debug level apears with info?
If i want to log info "Account id 4345 was deleted by Admin", why do i need to see all of these:

Answer 1

You will not face the issue in codeigniter 2

$config['log_threshold'] = array(1, 3);

in config/config.php

and

log_message('info', 'The purpose of some variable is to provide some value.');

where you want to log something will only print that message to the log file, no excess debug code.

BUT

In codeIgniter 3, Many system core files have

log_message('info', ******************);

Like

log_message('info', 'Config Class Initialized');
log_message('info', 'Controller Class Initialized');
log_message('info', 'Hooks Class Initialized');
............

That's why when

$config['log_threshold'] = array(1, 3);

or

$config['log_threshold'] = array(3);

or

$config['log_threshold'] = 3;

then all the undesired log messages are appearing in log file.

So, the one way is to resolve this is to extend all core files and change

log_message('info'

to

log_message('debug' 

or creating a new thresold, like

in config/config.php

$config['log_threshold'] = array(1, 5);

in core/MY_Log.php

protected $_levels = array('ERROR' => '1', 'DEBUG' => '2', 'INFO' => '3', 'ALL' => '4', 'USER_INFO' => '5');

Full core/MY_Log.php file

class MY_Log extends CI_Log
{

    protected $_log_path;
    protected $_threshold = 1;
    protected $_date_fmt = 'Y-m-d H:i:s';
    protected $_enabled = TRUE;
    protected $_levels = array('ERROR' => '1', 'DEBUG' => '2', 'INFO' => '3', 'ALL' => '4', 'USER_INFO' => '5');
