The log/auditlog package is used by Go services to log audit messages to file.
If the file is inaccessible for writing or encounters unexpected errors, the audit messages will be directed to STDOUT instead.
How To Use
To use the log package you first need to import the library into your project:
import "github.com/IOTechSystems/go-mod-edge-utils/pkg/log/auditlog"
To send an audit message to a file, you first need to create a Logger with service name, desired coverage level, desired io.Writer (write to file as default), configurations about log rotation, and then you can send audit messages (indicating the coverage level of the message using one of the various log function calls).
Audit messages can be logged as Base, Advanced, or Full.
logger := auditlog.InitLogger("SERVICE_NAME", "FULL", nil, auditlog.Configuration{})
details := map[string]interface{}{
"key1": "value1",
"key2": "value2",
}
logger.LogFull(auditlog.SeverityNormal, "Admin", "auditlog.ActionTypeLogin", "description", nil)
logger.LogAdvanced(auditlog.SeverityNormal, "Admin", auditlog.ActionTypeLogin, "description", details)
logger.LogBase(auditlog.SeverityCritical, "Admin", auditlog.ActionTypeDelete, "description", details)
An audit message is composed of the following elements.
Severity
The supported severity levels are Normal, Warning, and Critical.
Actor
An actor is the entity that initiated the action that is being audited.
Action Type
There are various action types that can be specified. The action type is the type of action that is being audited.
Description
The description is a string that describes the action that is being audited.
Details
The details is a map of key-value pairs that provide additional information about the action that is being audited.
