Exported fields

FieldDescriptionType
@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

Size in bytes of the response body.
long
http.response.status_code
HTTP response status code.

Proxy Metrics

The proxy_metrics data stream collects Istio proxy metrics.

An example event for proxy looks as following:

{
    "@timestamp": "2022-09-23T09:34:52.047Z",
    "data_stream": {
        "dataset": "istio.proxy_metrics",
        "namespace": "default",
        "type": "metrics"
    },
    "ecs": {
        "version": "8.6.0"
    },
    "event": {
        "agent_id_status": "verified",
        "dataset": "istio.proxy_metrics",
        "duration": 35506510,
        "ingested": "2022-09-23T09:34:52Z",
        "kind": "metric",
        "module": "istio"
    },
    "istio": {
        "proxy": {

                    "value": 0.000142478
                }
            },
            "labels": {
                "instance": "10.124.1.5:15020",
                "quantile": "0.25",

    }
}

Exported fields

FieldDescriptionTypeMetric 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

How to setup and test Istio locally

  1. 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).
  2. 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.
  3. Start elastic agents on Kubernetes cluster. The easiest way to achieve this is by using Fleet Server. You can find instructions here
  4. Download Istio cli following the instructions.
  5. 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.
  6. Deploy the sample application via instructions
  7. 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"
  1. Generate some traffic to the sample application
for i in $(seq 1 100); do curl -s -o /dev/null "http://$GATEWAY_URL/productpage"; done
  1. (Optional) You can visualize the graph of microservices in the sample app via instructions.
  2. Add the Istio integration from the registry.
  3. View logs and/or metrics from the Istio integration using the Discovery tab and selecting the right Data view
