Packageedit

An Elastic Package, or simply package for short, contains the dashboards, visualisations, and configurations to monitor the logs and metrics of a particular technology or group of related services, such as “MySQL”, or “System”.

The package consists of:

  • Name
  • Zero or more dashboards and visualisations and Canvas workpads
  • Zero or more ML job definitions
  • Zero or more data stream index templates

The package is versioned.

Integrationedit

An integration is a specific type of a package defining data streams used to observe a product using logs, metrics, and traces.

Data streamedit

A data stream is logical sub-division of an Integration package, dealing with a specific type of observable aspect of the service or product being observed. For example, the mysql package defines a data stream for collecting metrics and another data stream for collecting server logs.

A data stream defines all the assets needed to create an Elasticsearch data stream, for example: index templates and ingest pipelines. These assets are loaded into Elasticsearch when a user installs a package via the Fleet UI in Kibana.

A data stream also defines a policy template. Policy templates include variables that allow users to configure the data stream via the Fleet UI in Kibana. The resulting policy is interpreted by the Elastic Agent to collect relevant information from the product or service being observed.

Data streams are defined inside the data_stream folder located under the package’s root directory. Each data stream is defined in it’s own sub-folder.

The data stream consists of:

  • Field definitions (fields.yml files)
  • Zero or more ingest pipelines
  • An Elastic Agent policy template

Development Extensions: _dev directoriesedit

The _dev directory is part of the package-spec, and contains development resources. These development resources cover any types of files or folders needed only at development time. This includes resources needed for testing, but also includes any templates that might be used for generating documentation. In the future it could include other files or folders needed just at development time. It can be defined on the following levels:

  1. The package-level _dev folder contains files needed to set up the testing environment for that package. This environment setup is specified by files and folders in the _dev/deploy folder. For example, the apache package specifies how to spin up an Apache Docker container for testing.
  2. The data stream-level _dev folder contains test configuration files for various types of tests. For example, see the _dev/test folder under the apache/error data stream. The integrations have also asset and static tests. They don’t require config files, but configs can be used to mark them as optional.
