# File Log

`utility.file_log_viewer`

Displays log file contents in a terminal-style viewer directly on the canvas. Pairs naturally with the Log to File action.

Icon: `doc.text.magnifyingglass`

## Ports

### Inlets

Input (any)

### Outlets

No outlets. This is a terminal display node.

## Configuration

Field | Type | Default | Description
--- | --- | --- | ---
`filePath` | text | — | Path to the log file. Leave empty to read from the upstream `logFile` variable.
`maxLines` | number | 50 | Maximum number of lines to display from the end of the file.

## Use Case

Use the File Log viewer after a Log to File action to see the log output rendered directly on the canvas in a terminal-style format. This saves you from switching to a separate text editor to review log contents during workflow development.
