# Глоссарий

This topic lists words and abbreviations that are commonly used in the Harvest 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. Harvest 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://harvest.com/docs/harvest/latest/explore">Explore</a> topic.
    </td>
  </tr>
  <tr>
    <td style="vertical-align: top">Export/Import dashboard</td>
    <td>
      Harvest includes the ability to export your dashboards to a file containing JSON. Community members sometimes share their created dashboards on the <a href="https://harvest.com/harvest/dashboards">Harvest 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 (Harvest Cloud)</td>
    <td>
      Each Integration in Harvest Cloud uses the cloud agent to connect your data source to Harvest 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>
