Log Management

Audit trails for resource changes, system operations, and user logins

Overview

IM maintains three distinct audit logs. All data modifications, user logins, and role/organization changes are recorded automatically. Logs are queryable and cannot be deleted — even deleted users retain their log entries.

🔧

Resource Operation Log

Who changed which resource, old and new values.

📋

Operation Log

All button clicks: Add, Modify, Delete, Import, Export, Query operations.

🔑

Login Log

User login and logout events with IP address.

Resource Operation Log

Tracks every add, modify, delete, and import/export operation on IM resources. For Matrix/eMatrix-synced data, records old and new values of changed fields.

Field Type Req. Description
Handler string No Username of the operator who made the change
IP IP No IP address of the operator's session
Resource Type dropdown No Type of resource that was changed (e.g. ONT, Zone, Exchange)
Resource Name string No Name of the specific resource that changed
Resource Code string No Internal resource code/ID
Handling Time datetime No When the change was made
Resource Description string No Description of the change made
📝

Old and new values recorded for sync'd data

When Matrix/eMatrix sync updates a resource, IM records both the previous value and the new value. This requires agreement with IT on data volume and sync timing to avoid performance impact.

Operation Log

Records every user action across all modules — not just resource changes, but also queries, exports, and login events.

Field Type Req. Description
Resource Type string No Menu name where the action occurred (e.g. Customer Service, WO Management)
Resource Name string No Specific record name. For user/role/org menus, same as Resource Type.
Handler string No Username who performed the action
IP string No Client IP address
Operation Type dropdown No The specific action: Add, Modify, Delete, Query, Import, Export, Login, Logout
Operation Time From/To datetime range No Filter logs by time window
Remark string No Action-specific detail (see below)
Operation Time datetime No Exact timestamp of the action

Remark Field Contents by Module

Action name (Add/Clone/Modify/Delete/Import/Export) + resource name

Login Log

Tracks every login and logout event. IM enforces single-session logins — one account cannot be logged in from two places simultaneously.

Field Type Req. Description
Handler string No Account name that logged in/out
IP string No Client IP address
Operation Time From/To datetime range No Filter by time window
User Name string No Display name of the user
Account string No Account/username used to log in
Log Type string No Login or Logout
Operation Time datetime No Exact timestamp
ℹ

Single-session enforcement

IM enforces single login: if a user is already logged in, a new login attempt from another browser/IP will either fail or terminate the existing session, depending on configuration.

Log Retention

📝

Logs are never deleted

Log records are immutable — they cannot be manually deleted. Even when an operator's account is deleted from the system, their historical log entries are preserved.
