odoo11 log generation when i change data in a field using CSV Import

In Odoo11, When a field is changed by any user, It generates a log. for that I use track_visibility in field.

`audit_user = fields.Many2one('res.users', string='Audit User', track_visibility='onchange')
 audit_date = fields.Datetime(string="Audit Date", track_visibility='onchange')
 is_audited = fields.Boolean(string='Is Audited', track_visibility='onchange')`

That's The log is generated after any user change the data in these fields.

I can also update data of these fields using CSV Import of Odoo.

No log is generating when i changed field using CSV Import.

I want to generate a log when I change field data using CSV Import Option of Odoo.

It can be done by Method Overriding of Import function, providing you an example of custom log note generation code snippets

    self.env['mail.message'].create({
        'body': <your message>,
        'message_type': 'comment',
        'subtype_id': self.env.ref('mail.mt_note').id,
        'model': <your model name>,
        'res_id': <model's object id where you want to post>
    })
