# Glossary

This topic lists words and abbreviations that are commonly used in the Grafana documentation and community.

<table>
  <tr>
    <td style="vertical-align: top">Dashboard</td>
    <td>
      A set of one or more panels, organized and arranged into one or more rows, that provide an at-a-glance view of related information.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Data source</td>
    <td>
      A file, database, or service providing the data. Grafana supports several data sources by default, and can be extended to support additional data sources through plugins.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Exemplar</td>
    <td>
      An exemplar is any data that serves as a detailed example of one of the observations aggregated into a metric. An exemplar contains the observed value together with an optional timestamp and arbitrary labels, which are typically used to reference a trace.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Explore</td>
    <td>
      Explore allows a user to focus on building a query. Users can refine the query to return the expected metrics before building a dashboard. For more information, refer to the <a href="https://grafana.com/docs/grafana/latest/explore">Explore</a> topic.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Export/Import dashboard</td>
    <td>
      Grafana includes the ability to export your dashboards to a file containing JSON. Community members sometimes share their created dashboards on the <a href="https://grafana.com/grafana/dashboards">Grafana Dashboards page</a>. Dashboards previously exported or found on this site may be imported by other users.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Exporter</td>
    <td>
      An exporter translates data that comes out of a data source into a format that Prometheus can digest.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Integration (Grafana Cloud)</td>
    <td>
      Each Integration in Grafana Cloud uses the cloud agent to connect your data source to Grafana Cloud for visualizing. Note: Prometheus uses the word “integrations” to refer to software that exposes Prometheus metrics without needing an exporter, which is a different use of the same word we use here.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Graph</td>
    <td>
      A commonly-used visualization that displays data as points, lines, or bars.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Mixin</td>
    <td>
      A mixin is a set of Grafana dashboards and Prometheus rules and alerts, written in Jsonnet and packaged together in a bundle.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Panel</td>
    <td>
      Basic building block in Grafana, composed by a query and a visualization. Can be moved and resized within a dashboard.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Plugin</td>
    <td>
      An extension of Grafana that allows users to provide additional functionality to enhance their experience. The types of plugins currently supported are:

        </li>
        <li>
          <b>Data source plugin:</b> Extends Grafana with support for additional data sources.
        </li>
        <li>
          <b>Panel plugin:</b> Extends Grafana with additional visualization options.
        </li>
      </ul>
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Query</td>
    <td>
      Used to request data from a data source. The structure and format of the query depend on the specific data source.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Time series</td>
    <td>
      A series of measurements, ordered by time. Time series are stored in data sources and returned as the result of a query.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Trace</td>
    <td>
      An observed execution path of a request through a distributed system. For more information, refer to <a href="https://opentracing.io/docs/overview/what-is-tracing/">What is Distributed Tracing?</a>

  <tr>
    <td style="vertical-align: top">Transformation</td>
    <td>
      Transformations process the result set of a query before it’s passed on for visualization. For more information, refer to the <a href="https://grafana.com/docs/grafana/latest/panels/transformations">Transformations overview</a> topic.
