Understanding Yagna Requestor Logs

Yagna logs provide essential information for troubleshooting and monitoring your requestor node. This guide will show you how to locate your Yagna logs, understand their naming conventions, and configure the logging level for more detailed debugging.

Your Yagna logs are stored in a specific directory determined by your operating system and any custom settings you may have configured.

• Linux: ~/.local/share/yagna/yagna_rCURRENT.log
• macOS: ~/Library/Application Support/GolemFactory.yagna/yagna_rCURRENT.log
• Windows: %HOMEPATH%\AppData\Roaming\GolemFactory\yagna\yagna_rCURRENT.log

If you've set a custom location for your Yagna data using the YAGNA_DATADIR environment variable, your logs will be stored directly within that custom path.

To check if a custom data directory is in use, run the following command in your terminal:

echo $YAGNA_DATADIR

If this command returns a path, that's where your logs are located. Otherwise, they're in the default location for your operating system.

Yagna generates a new log file daily and each time the service restarts. Older logs are renamed with timestamps for archival purposes. The naming convention is as follows:

• yagna_rCURRENT.log: This file contains the current log.
• yagna_rYYYY-MM-DD_hh-mm-ss[restart-nnn].log: This represents an older log file, where:
  • YYYY-MM-DD_hh-mm-ss: The date and time (in UTC) when the log began.
  • restart-nnn: (Optional) If the log was created due to a restart, this indicates the n-th restart log for that day.

Yagna uses various log levels to categorize messages according to their severity. By default, the logging level is set to INFO, which includes the following types of messages:

• ERROR: Critical errors that require immediate attention.
• WARN: Warnings about potential issues that should be investigated.
• INFO: General information about your node's operations.

For more detailed debugging, you can enable the DEBUG level. This will provide significantly more information, useful for identifying and resolving issues within your application or when interacting with Golem's APIs.

How to Enable DEBUG Logs:

1. Open a terminal.
2. Start the yagna service with the RUST_LOG environment variable set to debug:

RUST_LOG=debug yagna service run

Your Yagna logs will now include DEBUG messages.
