There are many log files present in /var/log/packagecloud – the following list will attempt to include the most relevant files, their purpose, and what you can expect to find in them:
Application level logs
/var/log/packagecloud/packagecloud-rails/request_log.log - This file contains a log of all requests made to the service: requests from users against the web-UI andAPI requests. You will find information such as the timestamp a request was made, the IP address the request came from, the HTTP verb, the URL, the HTTP response code from the service, and the parameters of the request.
- /var/log/packagecloud/packagecloud-rails/rubygem_indexer.log - This file contains a log generated by the RubyGem indexer. This log contains timestamps of the various stages of RubyGem package reindexing and can be used to debug RubyGem metadata processing.
- /var/log/packagecloud/packagecloud-rails/rpm_indexer.log - This file contains a log generated by the RPM indexer. This log contains timestamps of the various stages of Rpm package reindexing and can be used to debug RPM metadata processing.
- /var/log/packagecloud/packagecloud-rails/resque.log - This file contains detailed logging information about the background job processing system where Debian, RPM, RubyGem, and Python index jobs are queued before being processed. This log will output information showing which jobs were queued, dequeued, and processed along with timestamp information.
- /var/log/packagecloud/packagecloud-rails/packagecloud.io.log - This file contains application level logs dependent upon the log level set (see the Application Logging section above). With the default settings, this log will contain any errors or exceptions encountered. Note that some error cases (e.g., ActiveRecord::RecordNotFound) may be seen in this file but are not necessarily problematic – some of these errors are handled by the app where it'll render a 404 (or similar) after the error is raised.
- /var/log/packagecloud/packagecloud-rails/package_create.log - This file contains application level logging related to package creation. If a package is unable to be created and an error is returned (typically a 422), this log will contain additional information as to why, specifically, a package creation returned a 422.
Metadata processing logs
- /var/log/packagecloud/packagecloud-rails/rubygem_indexer.log - This file contains a log generated by the RubyGem indexer. This log contains timestamps of the various stages of RubyGem package reindexing and can be used to debug RubyGem metadata processing.
- /var/log/packagecloud/packagecloud-rails/rpm_indexer.log - This file contains a log generated by the RPM indexer. This log contains timestamps of the various stages of Rpm package reindexing and can be used to debug RPM metadata processing.
- /var/log/packagecloud/packagecloud-rails/rpm_index_builder.log - This file contains a low-level log generated by the RPM indexer. This log documents the internals of the reindex process. Any debugging work on the Rpm indexer would be better suited by the rpm_indexer.log, but in some rare instances the rpm_index_builder.log may have additional, important information.
- /var/log/packagecloud/packagecloud-rails/python_indexer.log - This file contains detailed logging information about the Python indexer. This log contains timestamps of the various stages of Python package reindexing and can be used to debug Python metadata processing.
- /var/log/packagecloud/packagecloud-rails/deb_indexer.log - This file contains a log generated by the Debian indexer. This log contains timestamps of the various stages of Debian package reindexing and can be used to debug Debian metadata processing.
