Introduction
Hello Ninjas! Welcome back. You must have wondered what MetaData API is and how you can use it in PuppetDB. Don't worry, we have you covered. This article is going to discuss the topic of MetaData API version 1 in PuppetDB.
Before moving on to the main subject, the PuppetDB MetaData API version 1, let's first discuss PuppetDB.
An open-source storage solution for data generated by Puppet, is called PuppetDB. The initial release offers a drop-in storage service and stores configs.
PuppetDB is used to keep track of the nodes linked to a Puppet master. In addition, PuppetDB serves as a repository for exported resources. Resources that are defined on one node but used by another node are called exported resources.
Metadata API
The columns list and properties (i.e., dimensions and metrics) available in the APIs are returned via the metadata API. The variables that were returned are UI name, description, support for segments, and more.
The Metadata API can be used to
Find new columns quickly.
Utilize all metrics and dimensions available through the APIs.
Use of PuppetDB
PuppetDB provides many advantages, but its quick speed for store configs users is the most important feature. Every node, resource, relation, and fact across your entire network is known to PuppetDB because it is an all-in-one store. You can easily query and include all this data in your tools.
And also workflows or simply use it according to your interest. Also, it offers basics and a foundation for the development of new good tools.
Server Endpoint Time
In MetaData API version 1 in PuppetDB, the PuppetDB server's endpoint time can be retrieved using the /server-time endpoint.
/pdb/meta/v1/server-time
This metadata endpoint will return the time displayed by the clock on the PuppetDB server. To rule out the potential of time variations between the clocks on client workstations, this can be used as input to other time-based queries to PuppetDB.
To query PuppetDB data, the PuppetDB CLI project offers the Puppet method of control.

This endpoint uses no query strings or URL parameters.
Response format
The response will come in application/JSON format and contain a JSON map with the single key server time and the value of an ISO-8601 representation of the current time on the PuppetDB server Like the below examples.
In MetaData API version 1 in PuppetDB, the PuppetDB server's version information can be accessed using the /version endpoint.
/pdb/meta/v1/version
This query endpoint will return the operating PuppetDB server's version information.
This endpoint uses no query strings or URL parameters.
/pdb/meta/v1/version/latest
This request will show information about the most recent PuppetDB version.
Response format
The server time key in the response's JSON map, whose value is an ISO-8601 representation of the PuppetDB server's current time, will have the application or json extension.
{"version": "A.B.C"}
With real examples.
{"version": "1.0.0"}
Now, the present version of PuppetDB is below.
{"version": "7.11.1"}
Frequently Asked Questions

Data refers to the records on which a company relies, such as Users, Accounts, and Contacts, to name a few. Metadata, on the other hand, is data that describes other data.
What do puppet classes require?
Puppet classes are named blocks of code that are maintained in modules and used later when called by name. You can either declare classes in your manifests or assign them from an external node classifier to add them to a node's catalogue (ENC).
What is Puppetboard?
Puppetboard is a web interface to PuppetDB that aims to replace the reporting functionality of the open-source Puppet Enterprise console (previously: Puppet Dashboard).
What information is stored in PuppetDB?
PuppetDB is an open-source storage service for Puppet-generated data. This currently includes catalogues and facts but will be expanded shortly. The first release consists of a drop-in replacement for store configs and the inventory service.
