Log Entry

The logentry template represents an individual entry within a log.

Example config:

apiVersion: "config.istio.io/v1alpha2"
kind: logentry
metadata:
  name: accesslog
  namespace: istio-system
spec:
  severity: '"Default"'
  timestamp: request.time
  variables:
    sourceIp: source.ip | ip("0.0.0.0")
    destinationIp: destination.ip | ip("0.0.0.0")
    sourceUser: source.user | ""
    method: request.method | ""
    url: request.path | ""
    protocol: request.scheme | "http"
    responseCode: response.code | 0
    responseSize: response.size | 0
    requestSize: request.size | 0
    latency: response.duration | "0ms"
  monitored_resource_type: '"UNSPECIFIED"'

Template

The logentry template represents an individual entry within a log.

When writing the configuration, the value for the fields associated with this template can either be a literal or an expression. Please note that if the datatype of a field is not istio.policy.v1beta1.Value, then the expression’s inferred type must match the datatype of the field.

Field Type Description
variables map<string, istio.policy.v1beta1.Value>

Variables that are delivered for each log entry.
timestamp istio.policy.v1beta1.TimeStamp

Timestamp is the time value for the log entry
severity string

Severity indicates the importance of the log entry.
monitoredResourceType string

Optional. An expression to compute the type of the monitored resource this log entry is being recorded on. If the logging backend supports monitored resources, these fields are used to populate that resource. Otherwise these fields will be ignored by the adapter.
monitoredResourceDimensions map<string, istio.policy.v1beta1.Value>

Optional. A set of expressions that will form the dimensions of the monitored resource this log entry is being recorded on. If the logging backend supports monitored resources, these fields are used to populate that resource. Otherwise these fields will be ignored by the adapter.

istio.policy.v1beta1.TimeStamp

An instance field of type TimeStamp denotes that the expression for the field must evalaute to ValueType.TIMESTAMP

Objects of type TimeStamp are also passed to the adapters during request-time for the instance fields of type TimeStamp

Field Type Description
value google.protobuf.Timestamp

TimeStamp encoded as google.protobuf.Timestamp.

istio.policy.v1beta1.Value

An instance field of type Value denotes that the expression for the field is of dynamic type and can evalaute to any ValueType enum values. For example, when authoring an instance configuration for a template that has a field data of type istio.policy.v1beta1.Value, both of the following expressions are valid data: source.ip | ip("0.0.0.0"), data: request.id | ""; the resulting type is either ValueType.IP_ADDRESS or ValueType.STRING for the two cases respectively.

Objects of type Value are also passed to the adapters during request-time. There is a 1:1 mapping between oneof fields in Value and enum values inside ValueType. Depending on the expression’s evaluated ValueType, the equivalent oneof field in Value is populated by Mixer and passed to the adapters.

Field Type Description
stringValue string (oneof)

Used for values of type STRING
int64Value int64 (oneof)

Used for values of type INT64
doubleValue double (oneof)

Used for values of type DOUBLE
boolValue bool (oneof)

Used for values of type BOOL
ipAddressValue istio.policy.v1beta1.IPAddress (oneof)

Used for values of type IPAddress
timestampValue istio.policy.v1beta1.TimeStamp (oneof)

Used for values of type TIMESTAMP
durationValue istio.policy.v1beta1.Duration (oneof)

Used for values of type DURATION
emailAddressValue istio.policy.v1beta1.EmailAddress (oneof)

Used for values of type EmailAddress
dnsNameValue istio.policy.v1beta1.DNSName (oneof)

Used for values of type DNSName
uriValue istio.policy.v1beta1.Uri (oneof)

Used for values of type Uri
