Puppet
Plugin: go.d.plugin Module: puppet
Overview
This collector monitors Puppet metrics, including JVM heap and non-heap memory, CPU usage, and file descriptors.
It uses Puppet's metrics API endpoint /status/v1/services to gather the metrics.
This collector is supported on all platforms.
This collector supports collecting metrics from multiple instances of this integration, including remote instances.
Default Behavior
Auto-Detection
By default, it detects Puppet instances running on localhost that are listening on port 8140. On startup, it tries to collect metrics from:
Limits
The default configuration for this integration does not impose any limits on data collection.
Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Metrics
Metrics grouped by scope.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
Per Puppet instance
These metrics refer to the entire monitored application.
This scope has no labels.
Metrics:
Metric | Dimensions | Unit |
---|---|---|
puppet.jvm_heap | committed, used | MiB |
puppet.jvm_nonheap | committed, used | MiB |
puppet.cpu | execution, GC | percentage |
puppet.fdopen | used | descriptors |
Alerts
There are no alerts configured by default for this integration.
Setup
You can configure the puppet collector in two ways:
Method | Best for | How to |
---|---|---|
UI | Fast setup without editing files | Go to Nodes → Configure this node → Collectors → Jobs, search for puppet, then click + to add a job. |
File | If you prefer configuring via file, or need to automate deployments (e.g., with Ansible) | Edit go.d/puppet.conf and add a job. |
UI configuration requires paid Netdata Cloud plan.
Prerequisites
No action required.
Configuration
Options
The following options can be defined globally: update_every, autodetection_retry.
Config options
Group | Option | Description | Default | Required |
---|---|---|---|---|
Collection | update_every | Data collection interval (seconds). | 1 | no |
autodetection_retry | Autodetection retry interval (seconds). Set 0 to disable. | 0 | no | |
Target | url | Target endpoint URL. | https://127.0.0.1:8140 | yes |
timeout | HTTP request timeout (seconds). | 1 | no | |
HTTP Auth | username | Username for Basic HTTP authentication. | no | |
password | Password for Basic HTTP authentication. | no | ||
bearer_token_file | Path to a file containing a bearer token (used for Authorization: Bearer ). | no | ||
TLS | tls_skip_verify | Skip TLS certificate and hostname verification (insecure). | no | no |
tls_ca | Path to CA bundle used to validate the server certificate. | no | ||
tls_cert | Path to client TLS certificate (for mTLS). | no | ||
tls_key | Path to client TLS private key (for mTLS). | no | ||
Proxy | proxy_url | HTTP proxy URL. | no | |
proxy_username | Username for proxy Basic HTTP authentication. | no | ||
proxy_password | Password for proxy Basic HTTP authentication. | no | ||
Request | method | HTTP method to use. | GET | no |
body | Request body (e.g., for POST/PUT). | no | ||
headers | Additional HTTP headers (one per line as key: value). | no | ||
not_follow_redirects | Do not follow HTTP redirects. | no | no | |
force_http2 | Force HTTP/2 (including h2c over TCP). | no | no | |
Virtual Node | vnode | Associates this data collection job with a Virtual Node. | no |
via UI
Configure the puppet collector from the Netdata web interface:
- Go to Nodes.
- Select the node where you want the puppet data-collection job to run and click the ⚙ (Configure this node). That node will run the data collection.
- The Collectors → Jobs view opens by default.
- In the Search box, type puppet (or scroll the list) to locate the puppet collector.
- Click the + next to the puppet collector to add a new job.
- Fill in the job fields, then click Test to verify the configuration and Submit to save.
- Test runs the job with the provided settings and shows whether data can be collected.
- If it fails, an error message appears with details (for example, connection refused, timeout, or command execution errors), so you can adjust and retest.
via File
The configuration file name for this integration is go.d/puppet.conf
.
The file format is YAML. Generally, the structure is:
update_every: 1
autodetection_retry: 0
jobs:
- name: some_name1
- name: some_name2
You can edit the configuration file using the edit-config
script from the
Netdata config directory.
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/puppet.conf

Troubleshooting
Debug Mode
Important: Debug mode is not supported for data collection jobs created via the UI using the Dyncfg feature.
To troubleshoot issues with the puppet
collector, run the go.d.plugin
with the debug option enabled. The output
should give you clues as to why the collector isn't working.
-
Navigate to the
plugins.d
directory, usually at/usr/libexec/netdata/plugins.d/
. If that's not the case on your system, opennetdata.conf
and look for theplugins
setting under[directories]
.cd /usr/libexec/netdata/plugins.d/
-
Switch to the
netdata
user.sudo -u netdata -s
-
Run the
go.d.plugin
to debug the collector:./go.d.plugin -d -m puppet
To debug a specific job:
./go.d.plugin -d -m puppet -j jobName
Getting Logs
If you're encountering problems with the puppet
collector, follow these steps to retrieve logs and identify potential issues:
- Run the command specific to your system (systemd, non-systemd, or Docker container).
- Examine the output for any warnings or error messages that might indicate issues. These messages should provide clues about the root cause of the problem.
System with systemd
Use the following command to view logs generated since the last Netdata service restart:
journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep puppet
System without systemd
Locate the collector log file, typically at /var/log/netdata/collector.log
, and use grep
to filter for collector's name:
grep puppet /var/log/netdata/collector.log
Note: This method shows logs from all restarts. Focus on the latest entries for troubleshooting current issues.
Docker Container
If your Netdata runs in a Docker container named "netdata" (replace if different), use this command:
docker logs netdata 2>&1 | grep puppet
