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.

agent

The agent fields contain the data about the software entity, if any, that collects, detects, or observes events on a host, or takes measurements on a host. Examples include Beats. Agents may also run on observers. ECS agent.* fields shall be populated with details of the agent running on the host or observer where the event happened or the measurement was taken.

If no name is given, the name is often left empty.

type: keyword

example: foo
agent.type: Type of the agent. The agent type stays always the same and should be given by the agent used. In case of Filebeat the agent would always be Filebeat also if two Filebeat instances are run on the same machine.

client

A client is defined as the initiator of a network connection for events regarding sessions, connections, or bidirectional flow records. For TCP events, the client is the initiator of the TCP connection that sends the SYN packet(s). For other protocols, the client is generally the initiator or requestor in the network transaction. Some systems use the term "originator" to refer the client in TCP connections. The client fields describe details about the system acting as the client in the network event. Client fields are usually populated in conjunction with server fields. Client fields are generally not populated for packet-level events. Client / server representations can add semantic context to an exchange, which is helpful to visualize the data in certain situations. If your context falls in that category, you should still ensure that source and destination are filled appropriately.

client.address: Some event client addresses are defined ambiguously. The event will sometimes list an IP, a domain or a unix socket. You should always store the raw address in the .address field. Then it should be duplicated to .ip or .domain, depending on which one it is.

dns

Fields describing DNS queries and answers. DNS events should either represent a single DNS query prior to getting answers (dns.type:query) or they should represent a full exchange and contain the query details as well as all of the answers that were provided for this query (dns.type:answer).

dns.answers: An array containing an object for each answer section returned by the server. The main keys that should be present in these objects are defined by ECS. Records that have more information may contain more keys than what ECS defines. Not all DNS data sources give all details about DNS answers. At minimum, answer objects must contain the data key. If more information is available, map as much of it to ECS as possible, and add any additional fields to the answer objects as custom fields.

type: object
dns.answers.class: The class of DNS data contained in this resource record.

type: keyword

example: IN
dns.answers.data: The data describing the resource. The meaning of this data depends on the type and class of the resource record.

type: keyword

example: 10.10.10.10
dns.answers.name: The domain name to which this resource record pertains. If a chain of CNAME is being resolved, each answer’s name should be the one that corresponds with the answer’s data. It should not simply be the original question.name repeated.

type: keyword

example: www.google.com
dns.answers.ttl: The time interval in seconds that this resource record may be cached before it should be discarded. Zero values mean that the data should not be cached.

type: long

example: 180
dns.answers.type: The type of data contained in this resource record.

type: keyword

example: CNAME
dns.header_flags: Array of 2 letter DNS header flags. Expected values are: AA, TC, RD, RA, AD, CD, DO.

type: keyword

example: ['RD', 'RA']
dns.id: The DNS packet identifier assigned by the program that generated the query. The identifier is copied to the response.

type: keyword

example: 62111
dns.op_code: The DNS operation code that specifies the kind of query in the message. This value is set by the originator of a query and copied into the response.

type: keyword

example: QUERY
dns.question.class: The class of of records being queried.

type: keyword

example: IN
dns.question.name: The name being queried. If the name field contains non-printable characters (below 32 or above 126), those characters should be represented as escaped base 10 integers (\DDD). Back slashes and quotes should be escaped. Tabs, carriage returns, and line feeds should be converted to \t, \r, and \n respectively.

type: keyword

example: www.google.com
dns.question.registered_domain: The highest registered domain, stripped of the subdomain. For example, the registered domain for "foo.google.com" is "google.com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last two labels will not work well for TLDs such as "co.uk".

type: keyword

example: google.com
dns.question.type: The type of record being queried.

type: keyword

example: AAAA
dns.resolved_ip: Array containing all IPs seen in answers.data. The answers array can be difficult to use, because of the variety of data formats it can contain. Extracting all IP addresses seen in there to dns.resolved_ip makes it possible to index them as IP addresses, and makes them easier to visualize and query for.

type: ip

example: ['10.10.10.10', '10.10.10.11']
dns.response_code: The DNS response code.

type: keyword

example: NOERROR
dns.type: The type of DNS event captured, query or answer. If your source of DNS events only gives you DNS queries, you should only create dns events of type dns.type:query. If your source of DNS events gives you answers as well, you should create one event per query (optionally as soon as the query is seen). And a second event containing all query details as well as an array of answers.

type: keyword

example: answer

ecs

Meta-information specific to ECS.

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.

type: keyword

example: 1.0.0

required: True

error

These fields can represent errors of any kind. Use them for errors that happen while fetching events or in cases where the event itself contains an error.

error.code: Error code describing the error.

type: keyword
error.id: Unique identifier for the error.

type: keyword
error.message: Error message.

type: text

event

The event fields are used for context information about the log or metric event itself. A log is defined as an event containing details of something that happened. Log events must include the time at which the thing happened. Examples of log events include a process starting on a host, a network packet being sent from a source to a destination, or a network connection between a client and a server being initiated or closed. A metric is defined as an event containing one or more numerical or categorical measurements and the time at which the measurement was taken. Examples of metric events include memory pressure measured on a host, or vulnerabilities measured on a scanned host.

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.

type: keyword

example: user-password-change
event.category: Event category. This contains high-level information about the contents of the event. It is more generic than event.action, in the sense that typically a category contains multiple actions. Warning: In future versions of ECS, we plan to provide a list of acceptable values for this field, please use with caution.

type: keyword

example: user-management
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.

type: keyword

example: 4648
event.created: event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent’s or pipeline’s ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used.

type: date
event.dataset: Name of the dataset. If an event source publishes more than one type of log or events (e.g. access log, error log), the dataset is used to specify which one the event comes from. It’s recommended but not required to start the dataset name with the module name, followed by a dot, then the dataset name.

type: keyword

example: apache.access
event.duration: Duration of the event in nanoseconds. If event.start and event.end are known this value should be the difference between the end and start time.

type: long

format: duration
event.end: event.end contains the date when the event ended or when the activity was last observed.

type: date
event.hash: Hash (perhaps logstash fingerprint) of raw field to be able to demonstrate log integrity.

type: keyword

example: 123456789012345678901234567890ABCD
event.id: Unique ID to describe the event.

type: keyword

example: 8a4f500d
event.kind: The kind of the event. This gives information about what type of information the event contains, without being specific to the contents of the event. Examples are event, state, alarm. Warning: In future versions of ECS, we plan to provide a list of acceptable values for this field, please use with caution.

type: keyword

example: state
event.module: Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), event.module should contain the name of this module.

type: keyword

example: apache
event.original: Raw text message of entire event. Used to demonstrate log integrity. This field is not indexed and doc_values are disabled. It cannot be searched, but it can be retrieved from _source.

type: keyword

example: Sep 19 08:26:10 host CEF:0|Security| threatmanager|1.0|100| worm successfully stopped|10|src=10.0.0.1 dst=2.1.2.2spt=1232
event.outcome: The outcome of the event. If the event describes an action, this fields contains the outcome of that action. Examples outcomes are success and failure. Warning: In future versions of ECS, we plan to provide a list of acceptable values for this field, please use with caution.

type: keyword

example: success
event.provider: Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing).

type: keyword

example: kernel
event.risk_score: Risk score or priority of the event (e.g. security solutions). Use your system’s original value here.

type: float
event.risk_score_norm: Normalized risk score or priority of the event, on a scale of 0 to 100. This is mainly useful if you use more than one system that assigns risk scores, and you want to see a normalized value across all systems.

type: float
event.sequence: Sequence number of the event. The sequence number is a value published by some event sources, to make the exact ordering of events unambiguous, regarless of the timestamp precision.

type: long

format: string
event.severity: Severity describes the original severity of the event. What the different severity values mean can very different between use cases. It’s up to the implementer to make sure severities are consistent across events.

type: long

example: 7

format: string
event.start: event.start contains the date when the event started or when the activity was first observed.

type: date
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").

type: keyword
event.type: Reserved for future usage. Please avoid using this field for user data.

type: keyword

file

A file is defined as a set of information that has been created on, or has existed on a filesystem. File objects can be associated with host events, network events, and/or file events (e.g., those produced by File Integrity Monitoring [FIM] products or services). File fields provide details about the affected file associated with the event or metric.

This field set is meant to facilitate pivoting around a piece of data. Some pieces of information can be seen in many places in an ECS event. To facilitate searching for them, store an array of all seen values to their corresponding field in related.. A concrete example is IP addresses, which can be under host, observer, source, destination, client, server, and network.forwarded_ip. If you append all IPs to related.ip, you can then search for a given IP trivially, no matter where it appeared, by querying related.ip:a.b.c.d.

server

A Server is defined as the responder in a network connection for events regarding sessions, connections, or bidirectional flow records. For TCP events, the server is the receiver of the initial SYN packet(s) of the TCP connection. For other protocols, the server is generally the responder in the network transaction. Some systems actually use the term "responder" to refer the server in TCP connections. The server fields describe details about the system acting as the server in the network event. Server fields are usually populated in conjunction with client fields. Server fields are generally not populated for packet-level events. Client / server representations can add semantic context to an exchange, which is helpful to visualize the data in certain situations. If your context falls in that category, you should still ensure that source and destination are filled appropriately.
