# LogBox Directive

The logbox configuration directive — how ColdBox wires LogBox into your application.

The `logbox` structure is based on the LogBox declaration DSL and configures logging for your application.

📖 **Appenders, layouts, categories, and the full DSL live in the LogBox book:** [logbox.ortusbooks.com](https://logbox.ortusbooks.com/configuration/configuring-logbox/logbox-dsl)

```javascript
//LogBox DSL
logBox = {
    // The configuration file without fileextension to use for operation, instead of using this structure
    configFile = "config/LogBox",
    // Appenders
    appenders = {
        appenderName = {
            class="class.to.appender",
            layout="class.to.layout",
            levelMin=0,
            levelMax=4,
            properties={
                name  = value,
                prop2 = value 2
            }
    },
    // Root Logger
    root = {levelMin="FATAL", levelMax="DEBUG", appenders="*"},
    // Granualr Categories
    categories = {
        "coldbox.system" = { levelMin="FATAL", levelMax="INFO", appenders="*"},
        "model.security" = { levelMax="DEBUG", appenders="console"}
    }
    // Implicit categories
    debug  = ["coldbox.system.interceptors"],
    info   = ["model.class", "model2.class2"],
    warn   = ["model.class", "model2.class2"],
    error  = ["model.class", "model2.class2"],
    fatal  = ["model.class", "model2.class2"],
    off    = ["model.class", "model2.class2"]
};
```

> **Info** : If you do not define a logBox DSL structure, the framework will look for the default configuration file `config/LogBox.bx` (or `.cfc` for CFML). If it does not find it, then it will use the framework's default logging settings.

**ConfigFile**

You can use a configuration class instead of inline configuration by using this setting. The default value is `config/LogBox.bx` (or `.cfc` for CFML), so by convention you can just use that location. If no values are defined or no config file exists, the framework uses its shipped default configuration at `/coldbox/system/web/config/LogBox.cfc`.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://coldbox.ortusbooks.com/reference/configuration-directives/logbox.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
