Overview
A Puppet Face to display the classes and resources used in your last Puppet run and the last known status of some of the new Puppet Enterprise sub-systems which are also made available via Facter as custom facts. This allows the current status to be checked via the console.
Setup
Just install the module on the Puppet Master and run the puppet agent (or wait for it to run).
You will have access to the new subcommand and custom facts after this
Usage
Lastrun face
Once installed, you will have access to two new Puppet sub-commands on all nodes:
Information about last puppet run
This is designed to be a simple interface to enable monitoring of Puppet systems using external tools such as Nagios, Pager Duty, Sumo, etc
puppet lastrun info
Will return a JSON hash with very limited information about the last puppet run.
The data is parsed from the YAML file at
puppet agent --configprint lastrunreport so if you want more info (there's a
lot...) you could just parse this file directly. The advantage of this command
is that this logic is already done for you and we also check to see if the agent
is disabled.
Inside the returned JSON, the key alarm indicates whether there is a problem
running puppet on this host. The following conditions will cause an alarm:
status!=unchangedandchanged- Report is older then 1 hour
- No report is found
- Agent is disabled (
puppet agent --disable)
Alarms are aways accompanied by a human-readable translation of the problem encountered, see examples below.
Of course, if your not able to run the command at all or it returns an error, then your system has even bigger problems, such as no puppet agent installed, face not installed on master (or in this environment), or hell.. maybe SSH doesn't even work ;-). Be sure to catch such conditions as well with your reporting system and alarm on them appropriately.
Example output
System running normally

}

"status": "unchanged",

}
Puppet agent hasn't run for a long time

"status": "error",
"noop": false,

"corrective_change": false,
"report_age": 1936
}
A whole bunch of errors
{
"message": "Puppet agent disabled by user; status indicates error, check report; puppet report older then 3600 seconds, check running?",
"alarm": true,
"agent_disabled": true,
"time": "2017-04-20 20:31:44 -0400",
"status": "error",
"noop": false,
"environment": "production",
"corrective_change": false,
"report_age": 5425
}
Classes loaded during last Puppet agent run
puppet lastrun classes
Resources loaded during last Puppet agent run
puppet lastrun resources
Last Puppet catalog applied by agent
puppet lastrun catalog
Was Code Manager configured to be active during last Puppet agent run?
puppet lastrun code_manager
Note: Only makes sense on a PE Master
Was filesync configured to be active during last Puppet run?
puppet lastrun filesync
Note: Only makes sense on a PE Master
Was Puppet configured to use a static catalogue on the last Puppet run?
puppet lastrun static_catalogs
Custom facts
The lastrun custom structured fact will be present after installation and
contains:
code_manager_statusfilesync_statusstatic_catalogs_status
Example
"lastrun": {
"code_manager_status": "off",
"filesync_status": "indeterminate",
"static_catalogs_status": "indeterminate"
}
These correspond to executing the corresponding puppet lastface comand
before running the Puppet agent.
Limitations
Requires the module to be installed on your Puppet Master and run on each agent node at least once before the command becomes available
Testing
This module supports testing using PDQTest.
Test can be executed with:
bundle install
make
See .travis.yml for a working CI example
Development
PR's please :)
