# Data Enricher (classic)

## Overview <a href="#dataenricher-classic-overview" id="dataenricher-classic-overview"></a>

The Data Enricher is a software component that complements the information about [users](https://docs.nexthink.com/platform/references/references-classic/glossary-classic/user-classic) and [destinations](https://docs.nexthink.com/platform/references/references-classic/glossary-classic/destination-classic) that Collectors send to the Nexthink Cloud.

[Install the Data Enricher on a Windows Server](https://docs.nexthink.com/platform/configuring_nexthink/bringing-data-into-your-nexthink-instance/integrating-nexthink-with-third-party-tools/api-and-integrations-classic/data-enricher-classic/installing-data-enricher-classic) that is connected to the Active Directory and DNS servers within your corporate intranet.

## Information retrieved <a href="#dataenricher-classic-informationretrieved" id="dataenricher-classic-informationretrieved"></a>

The Data Enricher gets the following information from your servers:

* User information from Active Directory:
  * Distinguished Name
  * Name
  * Full name
  * Department
  * Job title
  * Location
  * Locality name
  * Country code
  * Organizational unit name
* Destination information from reverse DNS lookup:
  * Fully Qualified Domain Name

These data are similar to the data retrieved by Engine in an on-premises setup. The user fields Location, Locality name, Country code, and Organizational unit name are however available on Nexthink Experience only.

## Estimated processing time <a href="#dataenricher-classic-estimatedprocessingtime" id="dataenricher-classic-estimatedprocessingtime"></a>

For an available network bandwidth of 25 Mbps, the following times have been measured for a partial update, with the Data Enricher running on a Windows Server 2016 in an Azure VM (Standard\_F4s - 4 CPU cores, 8 GB memory).

Measured time for retrieving user information from AD:

| Number of users | Duration     |
| --------------- | ------------ |
| 500 k           | < 7 min      |
| 250 k           | < 3 min 30 s |
| 100 k           | < 1 min 30 s |
| 50 k            | < 40 s       |
| 20 k            | < 20 s       |
| 10 k            | < 10 s       |
| 1               | < 5 s        |

Measured time for retrieving the FQDN of destinations from the DNS server:

| Number of destinations | Duration |
| ---------------------- | -------- |
| 500 k                  | < 20 min |
| 250 k                  | < 10 min |
| 100 k                  | < 4 min  |
| 50 k                   | < 2 min  |
| 20 k                   | < 1 min  |
| 10 k                   | < 30 s   |
| 1                      | < 5 s    |
