from the Puppet function documentation  info  Log a message on the server at level info  debug  Log a message on the server at level debug    You have to look a your puppetmaster logfile to find your info debug messages   You may use  notify  The value is    yourvar        to produce some output to your puppet client

Just as alternative you may consider using execs     I wouldn t recommend it though   exec    this will output stuff     path        gt    bin     command     gt   echo Hello World      logoutput   gt  true      So when you run puppet you should find some output like so   notice   Stage main   Exec this will output stuff  returns  Hello World  notice   Stage main   Exec this will output stuff  returns  executed successfully notice  Finished catalog run in 0 08 seconds   The first line being logged output

You could go a step further and break into the puppet code using a breakpoint   http   logicminds github io blog 2017 04 25 break-into-your-puppet-code   This would only work with puppet apply or using a rspec test   Or you can manually type your code into the debugger console   Note  puppet still needs to know where your module code is at if you haven t set already   gem install puppet puppet-debugger  puppet module install nwops debug cat  gt  test pp  lt  lt  EOF   var1    test  debug  break   EOF   Should show something like   puppet apply test pp From file  test pp      1   var1    test       2    add  debug  break    where you want to stop in your code     gt  3  debug  break   1  gt  gt   var1   gt   test  2  gt  gt    https   www puppet-debugger com

You can run the client like this      puppet agent --test --debug --noop   with that command you get all the output you can get   excerpt puppet agent help    --test    Enable the most common options used for testing  These are  onetime      verbose    ignorecache    no-daemonize    no-usecacheonfailure      detailed-exitcodes    no-splay   and  show diff     NOTE  No need to include --verbose when you use the --test -t switch  it implies the --verbose as well

If  like me  you don t have access to the puppet master and need to print debug logs to inspect variables on your puppet client machine  you can try writing to a file from your puppet code itself   file     tmp puppet debug log     content   gt  inline template   lt     variable x to s   gt

If you want to notify user with different type of messages like information  debug  error  warning  alerts  critical and emergency messages then use    loglevel    metaparameter in puppet resources   With the use of loglevel you can use the same resources for different type of error messages   e g for producing debug messages you can use it as    notify   debug message         loglevel   gt  debug
