Use monolog to log activity in an Info log (see RFC 5424) to the database, and display this content in the staff UI.

This would require:

• PHP 5.3+ (i.e. Blesta 4+)
• A custom monolog process to acquire data necessary for logging, based on, or extended from, the bundled 'WebProcessor'
• A custom monolog handler to properly log that data to a MySQL database
• Model for display the log records
• UI for displaying under Logs as well as under the client's profile

log_info

• id (Auto increment ID for the entry)
• company_id (The ID of the company the action was triggered under)
• channel (The channel the action occurred under,. e.g. 'general', but may include 'module', 'gateway', 'plugin', etc. in the future)
• client_id (Client ID that the action relates to, if any)
• user_id (User that performed the action that triggered the log entry)
• user_ip (User's IP address)
• message (A JSON encoded string of message and context data)
• date_added

PK: id
Key: client_id
Key: user_id, company_id
Key: company_id, channel, user_ip

The message of a log would contain JSON encoded data. For example, if a client changes their login password the message might be stored as:

{
  "message": "Client #{{id_code}} updated user password.",
  "context": {
    "id_code": 123,
    "id": 20
  }

And displayed as: Client #123 updated user password.
