Itential Automation Gateway IAG provides the following logging tools to support your debugging efforts.
View Logs
To quickly view logs, set GATEWAY_LOG_LEVEL = DEBUG and run all iagctl commands with the --verbose flag.
Example
export GATEWAY_LOG_LEVEL="DEBUG"
iagctl get services --verbose
iagctl get services

Logging
Console Logs
To display console logs to the terminal, append --verbose to the command you are running. For example, running iagctl get services --verbose launches the gateway with console logs.
File Logs
In most cases, the gateway log file is located at GATEWAY_APPLICATION_WORKING_DIR/gateway.log. This location is used when users run CLI commands to accommodate gateway CLI users that do not have /var/log access.
When gateway is launched as a server or runner, the log file is located at GATEWAY_LOG_SERVER_DIR/gateway.log.
iagctl server`/`>_ iagctl runner
If the GATEWAY_LOG_SERVER_DIR location is not specified, the system uses the default location /var/log/gateway/gateway.log.
Log Format
By default, logs are displayed in the following format:
2024-02-14T09:18:28-06:00 INF grpc server is starting up
You can display logs in JSON format by setting the environment variables GATEWAY_LOG_FILE_JSON=true or GATEWAY_LOG_CONSOLE_JSON=true. JSON format allows easier integration with third-party software such as log aggregation programs.
JSON logs resemble the following format:
{"level":"info","time":"2024-02-14T09:18:28-06:00","message":"grpc server is starting up"}
By default, console logs have color formatting. To remove the color, set the environment variable GATEWAY_TERMINAL_NO_COLOR=true.
Log Levels
IAG supports different logging levels to denote the importance of a log as well as the severity of an error.
- Use the 
GATEWAY_LOG_LEVELenvironment variable to set the log level - The default value of 
GATEWAY_LOG_LEVELisINFO - Both file and console logs match the value set by 
GATEWAY_LOG_LEVEL 
Supported logging levels (ordered from least to most important) include:
- TRACE
 - DEBUG
 - INFO
 - WARN
 - ERROR
 - FATAL
 - DISABLED
 
IAG displays logs for the level set in GATEWAY_LOG_LEVEL as well as any logs of higher importance.
For example, if INFO logs are selected, a user will be shown logs for INFO, WARN, ERROR, and FATAL. They will not see DEBUG and TRACE logs.
