## Introduction

The tags beginning with `dhcp.bluecat` identify events generated by [BlueCat](https://bluecatnetworks.com/) DHCP services.

## Valid tags and data tables 

The full tag must have at least 3 levels. The first two are fixed as** **`dhcp.bluecat`. The third level identifies the type of events sent, and the fourth level indicates the event subtype. 

These are the valid tags and corresponding data tables that will receive the parsers' data:

| **Product / Service** | **Tags** | **Data tables** |
| --- | --- | --- |
| BlueCat DHCP server | `dhcp.bluecat.dhcpd` | `dhcp.bluecat.dhcpd` |
| `dhcp.bluecat.dhcpd.cef` | `dhcp.bluecat.dhcpd` |

## Send it

Data should be sent using the [relay](https://docs.devo.com/space/latest/96468993/Devo+Relay).
