Puppet - OpenTelemetry Collector

Thumbnail icon Thumbnail icon

Puppet is a software configuration management tool. Puppet can provision infrastructure and enforce desired configurations across new and existing servers. The Sumo Logic App for Puppet helps you monitor Puppet events. Puppet logs are sent to Sumo Logic through OpenTelemetry filelog receiver.


Fields creation in Sumo Logic for Puppet‚Äč

Following are the tags which will be created as part of Puppet App install if not already present. 

  • sumo.datasource. Has a fixed value of Puppet.


This section provides instructions for configuring log collection for Puppet running on a non-Kubernetes environment for the Sumo Logic App for Puppet. F

We use OpenTelemetry collector to gather the following data from Puppet:

  • Puppet Server logs. For more information about the logs location, see Puppet Server Logs.
  • Puppet Server Access logs. For more information about the logs location, see Puppet Server Logs.
  • Puppet Reports. Puppet generates reports in YAML format. SumoLogic supports report format 10. This is the format of reports output by Puppet versions 5.5.3 and newer. It is backward compatible with report format 9 (in Puppet versions 5.5.0 to 5.5.2). For more information about the puppet reports, see Puppet Reports.

The default Puppet Server Access log file is: /var/log/puppetlabs/puppetserver/puppetserver-access.log. If your Puppet Server Access logs are located elsewhere, please note the path this will be used later while app installation.

Puppet reports are in YAML format. They must be converted into JSON format before Sumo ingests them. You can convert the YAML files using the Sumo-provided shell script below:

#Get size in bytes**
   file_size=`du -b puppet_rpt_conversion.log | tr -s '\t' ' ' | cut -d' ' -f1`
   if [ $file_size -gt "$MaxFileSize" ];then  
       timestamp=`date +%s`
       mv puppet_rpt_conversion.log puppet_rpt_conversion.log.$timestamp
echo "YAML to JSON conversion started!!" >> "$log_file_name"
echo "Start Time: $(date)" >> "$log_file_name"
if [ ! -e last_run_date.tmp ]
date "+%Y-%m-%d" --date=1970-01-01 > last_run_date.tmp;
find . -maxdepth 2 -type f -name "*.yaml" -newermt "$(cat last_run_date.tmp)" |
while read f;
if [ -s "$f" ]
sed 1d "$f" > tmpfile;
ruby -rjson -ryaml -e "resource_list = ''
json = JSON.generate({});data = JSON.parse(json);
obj = JSON.parse(YAML.load_file('tmpfile').to_json);
data['host'] = obj['host'];
data['time'] = obj['time'];
data['configuration_version'] = obj['configuration_version'];
data['transaction_uuid'] = obj['transaction_uuid'];
data['report_format'] = obj['report_format'];
data['puppet_version'] = obj['puppet_version'];
data['status'] = obj['status'];
data['transaction_completed'] = obj['transaction_completed'];
data['noop'] = obj['noop'];
data['noop_pending'] = obj['noop_pending'];
data['environment'] = obj['environment'];
data['metrics'] = obj['metrics'];
data['resource_list'] = resource_list;
i = 0;
if i == 0 then
 tempdata = j[0];
 tempdata = ',' + j[0];
data['resource_list'] << tempdata;
i = i + 1;
puts data.to_json;
 |y|  logsres = y[1];
 logsres['transaction_uuid'] = obj['transaction_uuid'];
 logsres['environment'] = obj['environment'];
 logsres['host'] = obj['host'];
 puts logsres.to_json;
obj['logs'].each {
 |x|logsjson = x;
 logsjson['host'] = obj['host'];
 logsjson['transaction_uuid'] = obj['transaction_uuid'];
 logsjson['environment'] = obj['environment'];
 puts logsjson.to_json
echo "$f conversion status:" $? >> "$log_file_name"
date "+%d-%b-%Y %H:%M:%S" > last_run_date.tmp
echo "Conversion Completed. End Time: $(date)" >> "$log_file_name"

Copy this script to /opt/puppetlabs/server/data/puppetserver/reports with the name If Puppet is installed in a different location, copy the script to the correct path.

Configure a cron job to trigger the python script using crontab. Frequency of this job can be set following the instructions from here. Here is the command which needs to be configured as part of cron to trigger the script:

<frequency_expression> /opt/puppetlabs/server/data/puppetserver/reports/

Please modify the location of the if required in the above command. The execution of the script above will generate a log file named puppet_rpt_conversion.log. The path to this log file needs to be provided during the app installation.

Collection configuration and app installation‚Äč

As part of data collection setup and app installation, you can select the App from App Catalog and click on Install App. Follow the steps below.

Step 1: Set up Collector‚Äč


If you want to use an existing OpenTelemetry Collector, you can skip this step by selecting the Use an existing Collector option.

To create a new Collector:

  1. Select the Add a new Collector option.
  2. Select the platform where you want to install the Sumo Logic OpenTelemetry Collector.

This will generate a command that you can execute in the machine environment you need to monitor. Once executed, it will install the Sumo Logic OpenTelemetry Collector.


Step 2: Configure integration‚Äč

In this step, you will configure the yaml required for Puppet collection.

Path of the log file configured to capture puppet access logs and puppet report are needed to be given here. Refer to the Prerequisites section of this document.

Click on the Download YAML File button to get the yaml file.


Step 3: Send logs to Sumo Logic‚Äč

Once you have downloaded the yaml file as described in the previous step, follow the below steps based on your platform.

  1. Copy the yaml file to /etc/otelcol-sumo/conf.d/ folder in the Puppet instance that needs to be monitored.
  2. Place your Env file in the following directory:
  3. Restart the collector using:
      sudo systemctl restart otelcol-sumo

After successfully executing the above command, Sumo Logic will start receiving data from your host machine.

Click Next. This will install the app (dashboards and monitors) to your Sumo Logic Org.

Dashboard panels will start to fill automatically. It's important to note that each panel fills with data matching the time range query and received since the panel was created. Results won't immediately be available, but within 20 minutes, you'll see full graphs and maps.
