Puppet Server’s logging is routed through the Java Virtual Machine’s Logback library and configured in an XML file typically named
Note: This document covers basic, commonly modified options for Puppet Server logs. Logback is a powerful library with many options. For detailed information on configuring Logback, see the Logback Configuration Manual.
For advanced logging configuration tips specific to Puppet Server, such as configuring Logstash or outputting logs in JSON format, see Advanced Logging Configuration.
Puppet Server logging
By default, Puppet Server logs messages and errors to
/var/log/puppetlabs/puppetserver/puppetserver.log. The default log level is ‘INFO’, and Puppet Server sends nothing to
syslog. You can change Puppet Server’s logging behavior by editing
/etc/puppetlabs/puppetserver/logback.xml, and you can specify a different Logback config file in
Puppet Server picks up changes to
logback.xml at runtime, so you don’t need to restart the service for changes to take effect.
Puppet Server relies on
logrotate to manage the log file, and installs a configuration file at
/etc/logrotate.d/puppetserver (open source Puppet) or
/etc/logrotate.d/pe-puppetserver (Puppet Enterprise).
To modify Puppet Server’s logging level, change the
level attribute of the
root tag. By default, the logging level is set to
Supported logging levels, in order from most to least information logged, are
error. For instance, to enable debug logging for Puppet Server, change
Puppet Server profiling data is included at the
debug logging level.
You can change the file to which Puppet Server writes its logs in the
appender section named
F1. By default, the location is set to
... <appender name="F1" class="ch.qos.logback.core.FileAppender"> <file>/var/log/puppetlabs/puppetserver/puppetserver.log</file> ...
To change this to
/var/log/puppetserver.log, modify the contents of the
Note that the user account that owns the Puppet Server process must have write permissions to the destination path.
HTTP request logging
Puppet Server logs HTTP traffic separately, and this logging is configured in a different Logback configuration file located at
/etc/puppetlabs/puppetserver/request-logging.xml. To specify a different Logback configuration file, change the
access-log-config setting in Puppet Server’s
The HTTP request log uses the same Logback configuration format and settings as the Puppet Server log. It also lets you configure what it logs using patterns, which follow Logback’s
