LogDirectoryPath

LogDirectoryPath is the file path where the native logger writes output. Despite the name, the value is a full file path — not a directory.

Quick reference
Type string
Default "logs/log.txt"
Category Engine
Field on EngineParameters.LogDirectoryPath

What it does

When the native logger writes (mostly when EnableDebugLogging is true), output goes to this file. If the file does not exist, it is created; if it does, output is appended.

  • Default logs/log.txt — a file log.txt inside a logs folder, resolved relative to the current working directory.
  • Absolute path — write to a specific location regardless of working directory.

When to change it

Scenario Value
Default "logs/log.txt"
Per-environment log file "logs/staging.log", "logs/prod.log"
Centralized logging location "/var/log/aspose-llm/app.log"
Working directory is not writable Absolute path to a writable folder

Example

var preset = new Qwen25Preset();
preset.EngineParameters.EnableDebugLogging = true;
preset.EngineParameters.LogDirectoryPath = "/var/log/aspose-llm/app.log";

using var api = AsposeLLMApi.Create(preset, logger);

Ensure the parent directory exists and the process has write permission:

var logFile = "/var/log/aspose-llm/app.log";
Directory.CreateDirectory(Path.GetDirectoryName(logFile)!);
preset.EngineParameters.LogDirectoryPath = logFile;

Interactions

  • EnableDebugLogging — the main switch for output that this file receives.
  • ILogger passed to AsposeLLMApi.Create — complementary managed-side logging.
