What is an Elastic integration?

This integration is powered by Elastic Agent. Elastic Agent is a single, unified agent that you can deploy to hosts or containers to collect data and send it to the Elastic Stack. Behind the scenes, Elastic Agent runs the Beats shippers or Elastic Endpoint required for your configuration. Please refer to our documentation for a detailed comparison between Beats and Elastic Agent.

Prefer to use Beats for this use case? See Filebeat modules for logs or Metricbeat modules for metrics.

Overview

This integration collects logs and metrics from Microsoft DHCP logs.

Compatibility

This integration has been made to support the DHCP log format from Windows Server 2008 and later.

Logs

Ingest logs from Microsoft DHCP Server, by default logged with the filename format: %windir%\System32\DHCP\DhcpSrvLog-*.log

Logs may also be ingested from Microsoft DHCPv6 Server, by default logged with the filename format: %windir%\System32\DHCP\DhcpV6SrvLog-*.log

Relevant documentation for Microsoft DHCP can be found on [this]https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/dd183591(v=ws.10) location.

An example event for log looks as following:

{
    "@timestamp": "2001-01-01T01:01:01.000-05:00",

Exported fields

FieldDescriptionType
@timestamp
Event timestamp.
date
data_stream.dataset
Data stream dataset.
constant_keyword
data_stream.namespace
Data stream namespace.
constant_keyword
data_stream.type
Data stream type.
constant_keyword
ecs.version
ECS version this event conforms to. ecs.version is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events.
keyword
event.action
The action captured by the event. This describes the information in the event. It is more specific than event.category. Examples are group-add, process-started, file-created. The value is normally defined by the implementer.
keyword
event.code
Identification code for this event, if one exists. Some event sources use event codes to identify messages unambiguously, regardless of message language or wording adjustments over time. An example of this is the Windows Event ID.
keyword
event.dataset
Event dataset
constant_keyword
event.ingested
Timestamp when an event arrived in the central data store. This is different from @timestamp, which is when the event originally occurred. It's also different from event.created, which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: @timestamp < event.created < event.ingested.
date
event.kind
This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. event.kind gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not.
keyword
event.module
Event module
constant_keyword
event.original
Raw text message of entire event. Used to demonstrate log integrity or where the full log message (before splitting it up in multiple parts) may be required, e.g. for reindex. This field is not indexed and doc_values are disabled. It cannot be searched, but it can be retrieved from _source. If users wish to override this and index this field, please see Field data types in the Elasticsearch Reference.
keyword
event.timezone
This field should be populated when the event's timestamp does not include timezone information already (e.g. default Syslog timestamps). It's optional otherwise. Acceptable timezone formats are: a canonical ID (e.g. "Europe/Amsterdam"), abbreviated (e.g. "EST") or an HH:mm differential (e.g. "-05:00").
keyword
host.domain
Name of the domain of which the host is a member. For example, on Windows this could be the host's Active Directory domain or NetBIOS domain name. For Linux this could be the domain of the host's LDAP provider.
keyword
host.ip
Host ip addresses.
ip
host.mac
Host MAC addresses. The notation format from RFC 7042 is suggested: Each octet (that is, 8-bit byte) is represented by two [uppercase] hexadecimal digits giving the value of the octet as an unsigned integer. Successive octets are separated by a hyphen.
keyword
input.type
keyword
log.file.path
Full path to the log file this event came from, including the file name. It should include the drive letter, when appropriate. If the event wasn't read from a log file, do not populate this field.
keyword
log.offset
long
message
For log events the message field contains the log message, optimized for viewing in a log viewer. For structured logs without an original message field, other fields can be concatenated to form a human-readable summary of the event. If multiple messages exist, they can be combined into one message.
match_only_text
microsoft.dhcp.correlation_id
The NAP correlation ID related to the client/server transaction.
keyword
microsoft.dhcp.dhc_id
The related DHCID (DHC DNS record).
keyword
microsoft.dhcp.dns_error_code
DNS error code communicated to client.
keyword
microsoft.dhcp.duid.hex
The related DHCP Unique Identifier (DUID) for the host (DHCPv6).
keyword
microsoft.dhcp.duid.length
The length of the DUID field.
keyword
microsoft.dhcp.error_code
DHCP server error code.
keyword
microsoft.dhcp.probation_time
The probation time before lease ends on specific IP.
keyword
microsoft.dhcp.relay_agent_info
Information about DHCP relay agent used for the DHCP request.
keyword
microsoft.dhcp.result
The DHCP result type, for example "NoQuarantine", "Drop Packet" etc.
keyword

ip
observer.mac
MAC addresses of the observer. The notation format from RFC 7042 is suggested: Each octet (that is, 8-bit byte) is represented by two [uppercase] hexadecimal digits giving the value of the octet as an unsigned integer. Successive octets are separated by a hyphen.
keyword
tags
List of keywords used to tag each event.
