The following sections describe the most commonly used log files and debugging tools available in Satellite.
17.1. Increasing logging levels to help with debugging Copy linkLink copied to clipboard!
You can increase the logging level of Satellite components to troubleshoot Satellite. Increasing the logging level to debug provides the most detailed information. The default logging level is info.
17.1.1. Increasing the logging level for the Foreman application Copy linkLink copied to clipboard!
To increase logging for the Foreman application:
Set the logging level to
debug:satellite-installer --foreman-logging-level debug
# satellite-installer --foreman-logging-level debugCopy to Clipboard Copied! Toggle word wrap Toggle overflow After you complete debugging, reset the logging level to the default value:
satellite-installer --reset-foreman-logging-level
# satellite-installer --reset-foreman-logging-levelCopy to Clipboard Copied! Toggle word wrap Toggle overflow
For more information about Satellite logging settings, use satellite-installer with the --full-help option:
satellite-installer --full-help | grep logging
# satellite-installer --full-help | grep logging
17.1.2. Increasing the logging level for Hammer Copy linkLink copied to clipboard!

17.8. Utilities for processing log information Copy linkLink copied to clipboard!
You can collect information from log files to troubleshoot Satellite.
- sosreport
The
sosreportcommand collects configuration and diagnostic information from a Linux system, such as the running Kernel version, loaded modules, running services, and system and service configuration files. This output is stored in a tar file located at/var/tmp/sosreport-XXX-20171002230919.tar.xz.For more information, run
sosreport --helpor see What is a sosreport and how can I create one?.ImportantThe
sosreportcommand removes security information such as passwords, tokens, and keys while collecting information. However, the tar files can still contain sensitive information about the Satellite Server. Send the tar files directly to the intended recipient and not to a public target.- foreman-tail
