puppetlabs/puppet_metrics_collector — version 8.0.0 Jun 23rd 2023

Table of Contents


This module collects metrics provided by the status endpoints of Puppet Enterprise services. The metrics can be used to identify performance issues that may be addressed by performance tuning.

For PE versions older than 2019.8.5, access to the /metrics/v2 API endpoint is restricted to localhost as a mitigation for CVE-2020-7943. This module requires access the /metrics/v2 API to collect a complete set of performance metrics from PuppetDB. Refer to Configuration for Distributed Metrics Collection for a workaround.



Install this module with puppet module install puppetlabs-puppet_metrics_collector or add it to your Puppetfile.

To activate this module, classify your Primary Server with the puppet_metrics_collector class using your preferred classification method. Below is an example using site.pp.

node '' {
  include puppet_metrics_collector

Optionally, you can gather basic system metrics. Unlike service metrics, system metrics have to be enabled locally on each PE Infrastructure Host, and the resulting data will be stored locally on that host. This functionality depends on sysstat.

node '' {
  include puppet_metrics_collector
  include puppet_metrics_collector::system

node '', ',' {
  include puppet_metrics_collector::system

Note: Do not include the top-level puppet_metrics_collector class on any PE Infrastructure Host other than the Primary Server, otherwise it will collect the same data as the Primary Server.


This module automatically configures the hosts it collects metrics from by querying PuppetDB for PE Infrastructure Hosts. If there is an error with the automatic configuration of hosts, refer to Manual Configuration of Hosts.


For each Puppet Enterprise service (Puppet Server, PuppetDB, Orchestrator, Ace, Bolt, and ActiveMQ) there are associated <service_name>_ensure, <service_name>_hosts, and <service_name>_port parameters. Refer to manifests/init.pp for details.


String: Output directory for collected metrics.

Defaults to /opt/puppetlabs/puppet-metrics-collector.


Integer: How often to collect metrics, in minutes.

Defaults to 5.


Integer: How long to retain collect metrics, in days.

Defaults to 90.

Metrics Server Parameters

The following set of parameters begining with metrics_server_ allows for the specification of a server type to use to generate and (in some cases) send data to a specified metrics server. Currently, both influxdb and graphite types allow for the transfer of data while splunk_hec only generates data.


Optional Enum['influxdb','graphite','splunk_hec']: The metrics server type to send data to.

Currently, this module supports influxdb, graphite, and splunk_hec metrics server types.

For the influxdb metrics server type, a metrics_server_db_name must be provided.

For the splunk_hec metrics server type, data cannot be sent to a server, however the command will format the JSON output using the splunk_hec module, which is a requirement for this option. The splunk_hec module can be found on the Forge or GitHub. Setup instructions for the splunk_hec module can be found within that module's README.


Optional String: The hostname of the metrics server to send data to.

Defaults to undef.


Optional Integer: The port number of the metrics server to send data to.

Defaults to undef.


Optional String: The database name on the metrics server to send data to.

Required for metrics_server_type of influxdb.

Defaults to undef.


Optional String: Allows you to define the command that is executed to gather metrics.

Defaults to undef.


Searching Metrics

Metrics are formatted as a JSON hash on one line. In order to convert the metric files into a multi-line format, they can be processed with python -m json.tool as per below.

cd /opt/puppetlabs/puppet-metrics-collector
for i in <service_name>/*.json; do echo "$(python -m json.tool < $i)" > $i; done

You can search for useful information by performing a grep, run from inside the directory containing the metrics

cd /opt/puppetlabs/puppet-metrics-collector
grep -oP '"<metric_name>,*?,' <service_name>/*.json

or JQ if available

cd /opt/puppetlabs/puppet-metrics-collector
jq '.. |."<metric_name>"? | select(. != null)| input_filename , .' -- <service_name>/*.json

Since the metrics are archived once per day, you can only search metrics for the current day. To search older metrics, decompress the archived files into a subdirectory of /tmp and run your search from inside that directory.

Searching Puppetserver Metrics


grep -oP '"average-free-jrubies.*?,' puppetserver/*.json

jq '.. |."average-free-jrubies"? | select(. != null)| input_filename , .' -- puppetserver/*.json


Searching PuppetDB Metrics


grep -oP '"queue_depth.*?,' puppetdb/*.json

puppetdb/ "queue_depth": 0,
puppetdb/ "queue_depth": 0,
puppetdb/ "queue_depth": 0,
jq '.. |."queue_depth "? | select(. != null)| input_filename , .' -- puppetdb/*.json


Sharing Metrics Data

When working with Support, you may be asked for an archive of collected metrics data.

This module provides a script, create-metrics-archive to archive metrics data for sending to Support.


This script creates the archive in the current working directory.

It takes an optional -m or --metrics-directory parameter (default /opt/puppetlabs/puppet-metrics-collector) to specify an alterate metrics directory to archive.

It takes an optional -r or --retention-days parameter (default: 30) to limit the number of days to include in the archive.

[root@primary ~]# /opt/puppetlabs/puppet-metrics-collector/scripts/create-metrics-archive
Created metrics archive: /root/puppet-metrics-collector-20200203T123456Z.tar.gz


Directory Layout

This module creates an output directory with one subdirectory for each Puppet Enterprise service (Puppet Server, PuppetDB, Orchestrator, Ace, Bolt, and ActiveMQ) that this module has been configured to collect. Each service directory has one subdirectory for each host. Each host directory contains one JSON file, collected every 5 minutes. Once per day, the metrics for each service are archived and compressed.

Systemd Timers

This module creates two systemd timers for each Puppet Enterprise service:

  • One to collect the metrics
    • Runs as per collection_frequency
  • One to archive collected metrics and delete metrics older than the retention period, as per retention_days
    • Runs at randomly selected time between 12:00 AM and 3:00 AM

Alternate Setup

Temporary Installation

While a permanent installation is recommended, this module can be temporarily installed with the following commands.

puppet module install puppetlabs-puppet_metrics_collector --modulepath /tmp;
puppet apply -e "class { 'puppet_metrics_collector': }" --modulepath /tmp;

Manual Configuration of Hosts

If necessary, you can manually configure this module by specifying parameters via the class declaration or via Hiera data. The preferred method is via Hiera data. The following examples show you how to specify those parameters for different infrastructures, and assumes you declare this module on the Primary Server.

Monolithic Infrastructure with Compilers

Hiera Data Example
 - ''
 - ''
 - ''
 - ''
Class Declaration Example
class { 'puppet_metrics_collector':
  puppetserver_hosts => [
  puppetdb_hosts     => [''],

Configuration for Distributed Metrics Collection

This option collect metrics on each PE Infrastructure Host instead of collecting metrics centrally on the Primary Server. This option is discouraged, but allows for the collection of metrics when the Primary Server cannot access the API endpoints of the other PE Infrastructure Hosts. Classify each PE Infrastructure Host with this module, specifying the following parameters.

When classifying a Compiler, specify these additional parameters:

class { 'puppet_metrics_collector':
  puppetserver_hosts          => [''],
  puppetdb_metrics_ensure     => absent,
  orchestrator_metrics_ensure => absent,
  ace_metrics_ensure          => absent,
  bolt_metrics_ensure         => absent,

When classifying a PuppetDB Host, specify these additional parameters:

class { 'puppet_metrics_collector':
  puppetdb_hosts              => [''],
  puppetserver_metrics_ensure => absent,
  orchestrator_metrics_ensure => absent,
  ace_metrics_ensure          => absent,
  bolt_metrics_ensure         => absent,
