Field	Description	Type
@timestamp	Event timestamp.	date
agent.ephemeral_id	Ephemeral identifier of this agent (if one exists). This id normally changes across restarts, but `agent.id` does not.	keyword
agent.id	Unique identifier of this agent (if one exists). Example: For Beats this would be beat.id.	keyword
agent.name	Custom name of the agent. This is a name that can be given to an agent. This can be helpful if for example two Filebeat instances are running on the same host but a human readable separation is needed on which Filebeat instance data is coming from.	keyword
agent.type	Type of the agent. The agent type always stays 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.	keyword
agent.version	Version of the agent.	keyword
container.runtime	Runtime managing this container.	keyword
data_stream.dataset	Data stream dataset.	constant_keyword
data_stream.namespace	Data stream namespace.	constant_keyword
data_stream.type	Data stream type.	constant_keyword
destination.address	Some event destination 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.	keyword
destination.domain	The domain name of the destination system. This value may be a host name, a fully qualified domain name, or another host naming format. The value may derive from the original event or be added from enrichment.	keyword
destination.ip	IP address of the destination (IPv4 or IPv6).	ip
destination.port	Port of the destination.	long
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
error.message	Error message.	match_only_text
event.category	This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. `event.category` represents the "big buckets" of ECS categories. For example, filtering on `event.category:process` yields all events relating to process activity. This field is closely related to `event.type`, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories.	keyword
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.	date
event.dataset	Event dataset	constant_keyword
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.	long
event.id	Unique ID to describe the event.	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.outcome	This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. `event.outcome` simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of `event.outcome`, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with `event.type:info`, or any events for which an outcome does not make logical sense.	keyword
event.type	This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. `event.type` represents a categorization "sub-bucket" that, when used along with the `event.category` field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types.	keyword
http.request.body.bytes	Size in bytes of the request body.	long
http.request.id	A unique identifier for each HTTP request to correlate logs between clients and servers in transactions. The id may be contained in a non-standard HTTP header, such as `X-Request-ID` or `X-Correlation-ID`.	keyword
http.request.method	HTTP request method. The value should retain its casing from the original event. For example, `GET`, `get`, and `GeT` are all considered valid values for this field.	keyword
http.response.body.bytes	Size in bytes of the response body.	long
http.response.status_code	HTTP response status code.	long
http.version	HTTP version.	keyword
istio.access.authority	The value of the Host (HTTP/1.1) or Authority (HTTP/2) header.	keyword
istio.access.bytes.received	For HTTP/THRIFT this field is the body bytes received. For TCP this field is the downstream bytes received on connection. For UDP this field is not implemented (0).	long
istio.access.bytes.sent	For HTTP/THRIFT this field is the body bytes sent. For WebSocket connection it will also include response header bytes. For TCP this field is the downstream bytes sent on connection. For UDP this field is not implemented (0).	long
istio.access.connection_termination_details	Connection termination details may provide additional information about why the connection was terminated by Envoy for L4 reasons.	text
istio.access.downstream.local_address	Local address of the downstream connection. If the address is an IP address it includes both address and port.	keyword
istio.access.downstream.remote_address	Remote address of the downstream connection. If the address is an IP address it includes both address and port.	keyword
istio.access.duration	For HTTP/THRIFT this field is the total duration in milliseconds of the request from the start time to the last byte out. For TCP this field is the total duration in milliseconds of the downstream connection. For UDP this field is not implemented (0).	long
istio.access.log	Access log in custom Json format.	keyword
istio.access.requested_server_name	For HTTP/TCP/THRIFT this field is a string value set on ssl connection socket for Server Name Indication (SNI). For UDP this field is not implemented ("-").	keyword
istio.access.response.code_details	Additional information about the response code, such as who set it (the upstream or envoy) and why. For TCP/UDP this field is not implemented ("-").	text
istio.access.response.flags	Additional details about the response or connection. Field not implemented ("-") for UDP.	keyword
istio.access.route_name	For HTTP/TCP this field is the name of the route. For UDP this field is not implemented ("-").	keyword
istio.access.upstream.cluster	Upstream cluster to which the upstream host belongs to. alt_stat_name will be used if provided.	text
istio.access.upstream.host	Upstream host URL (e.g., tcp://ip:port for TCP connections).	keyword
istio.access.upstream.local_address	Local address of the upstream connection. If the address is an IP address it includes both address and port.	keyword
istio.access.upstream.service_time	Envoy Upstream service time.	long
istio.access.upstream.transport_failure_reason	For HTTP if upstream connection failed due to transport socket (e.g. TLS handshake), provides the failure reason from the transport socket. The format of this field depends on the configured upstream transport socket. For TCP/UDP this field is not implemented ("-").	text
istio.access.x_forwarded_for	x_forwarded_for (XFF) is a standard proxy header which indicates the IP addresses that a request has flowed through on its way from the client to the server.	keyword
log.file.device_id	ID of the device containing the filesystem where the file resides.	keyword
log.file.fingerprint	The sha256 fingerprint identity of the file when fingerprinting is enabled.	keyword
log.file.idxhi	The high-order part of a unique identifier that is associated with a file. (Windows-only)	keyword
log.file.idxlo	The low-order part of a unique identifier that is associated with a file. (Windows-only)	keyword
log.file.inode	Inode number of the log file.	keyword
log.file.vol	The serial number of the volume that contains a file. (Windows-only)	keyword
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
network.community_id	A hash of source and destination IPs and ports, as well as the protocol used in a communication. This is a tool-agnostic standard to identify flows. Learn more at https://github.com/corelight/community-id-spec.	keyword
network.protocol	In the OSI Model this would be the Application Layer protocol. For example, `http`, `dns`, or `ssh`. The field value must be normalized to lowercase for querying.	keyword
network.transport	Same as network.iana_number, but instead using the Keyword name of the transport layer (udp, tcp, ipv6-icmp, etc.) The field value must be normalized to lowercase for querying.	keyword
related.ip	All of the IPs seen on your event.	ip
source.address	Some event source 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.	keyword
source.as.number	Unique number allocated to the autonomous system. The autonomous system number (ASN) uniquely identifies each network on the Internet.	long
source.as.organization.name	Organization name.	keyword
source.as.organization.name.text	Multi-field of `source.as.organization.name`.	match_only_text

Field	Description	Type	Metric Type
@timestamp	Event timestamp.	date
agent.id	Unique identifier of this agent (if one exists). Example: For Beats this would be beat.id.	keyword
cloud.account.id	The cloud account or organization id used to identify different entities in a multi-tenant environment. Examples: AWS account id, Google Cloud ORG Id, or other unique identifier.	keyword
cloud.availability_zone	Availability zone in which this host, resource, or service is located.	keyword
cloud.instance.id	Instance ID of the host machine.	keyword
cloud.provider	Name of the cloud provider. Example values are aws, azure, gcp, or digitalocean.	keyword
cloud.region	Region in which this host, resource, or service is located.	keyword
container.id	Unique container id.	keyword
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
error.message	Error message.	match_only_text
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
host.name	Name of the host. It can contain what `hostname` returns on Unix systems, the fully qualified domain name, or a name specified by the user. The sender decides which value to use.	keyword
istio.proxy.labels.*	Istio Proxy metric labels	object
istio.proxy.labels_id	Fingerprint generated by the labels.	keyword
istio.proxy.metrics.*.counter	Istio Proxy counter metric	object	counter
istio.proxy.metrics.*.histogram	Istio Proxy histogram metric	object
istio.proxy.metrics.*.rate	Istio Proxy rated counter metric	object	gauge
istio.proxy.metrics.*.value	Istio Proxy gauge metric	object	gauge

How to setup and test Istio locally

Setup a Kubernetes cluster. Since the Istio sample app requires lots of RAM (> 10GB) it's preferable to use a managed Kubernetes cluster (any cloud provider will do).
Setup a EK cluster on Elastic Cloud. For the same reason that Istio sample app requires a lot of RAM, it's unfeasible to run the Elastic cluster on your laptop via elastic-package. As an alternative ECK might be used as well.
Start elastic agents on Kubernetes cluster. The easiest way to achieve this is by using Fleet Server. You can find instructions here
Download Istio cli following the instructions.
Install Istio via instructions. The namespace default is used with this basic installation. This is the same namespace where we are going to run the Istio sample app.
Deploy the sample application via instructions
Open the application to external traffic and determine the ingress IP and ports. This step is slightly different depending where Kubernetes is running. More info at here and here. The following commands should be enough to get this working.

		kubectl apply -f samples/bookinfo/networking/bookinfo-gateway.yaml
istioctl analyze

# since we are using a cloud environment with an external load balancer
export INGRESS_HOST=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
export INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="http2")].port}')
export SECURE_INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="https")].port}')
export GATEWAY_URL=$INGRESS_HOST:$INGRESS_PORT

	

From the same terminal run the following command to open a browser to that link. This should verify that the sample application is reachable.

open "http://$GATEWAY_URL/productpage"

Generate some traffic to the sample application

		for i in $(seq 1 100); do curl -s -o /dev/null "http://$GATEWAY_URL/productpage"; done

	

(Optional) You can visualize the graph of microservices in the sample app via instructions.
Add the Istio integration from the registry.
View logs and/or metrics from the Istio integration using the Discovery tab and selecting the right Data view
