Constructors

LogEntry()

public LogEntry(LogEntry other)
Parameter
Name Description
other LogEntry

Properties

HasTextPayload

public bool HasTextPayload { get; }

Gets whether the "text_payload" field is set

Property Value
Type Description
bool

HttpRequest

public HttpRequest HttpRequest { get; set; }

Optional. Information about the HTTP request associated with this log entry, if applicable.

Property Value
Type Description
HttpRequest

InsertId

public string InsertId { get; set; }

Optional. A unique identifier for the log entry. If you provide a value, then Logging considers other log entries in the same project, with the same timestamp, and with the same insert_id to be duplicates which are removed in a single query result. However, there are no guarantees of de-duplication in the export of logs.

If the insert_id is omitted when writing a log entry, the Logging API assigns its own unique identifier in this field.

In queries, the insert_id is also used to order log entries that have the same log_name and timestamp values.

Property Value
Type Description
string

JsonPayload

public Struct JsonPayload { get; set; }

The log entry payload, represented as a structure that is expressed as a JSON object.

Property Value
Type Description
Struct

Labels

public MapField<string, string> Labels { get; }

Optional. A map of key, value pairs that provides additional information about the log entry. The labels can be user-defined or system-defined.

User-defined labels are arbitrary key, value pairs that you can use to classify logs.

System-defined labels are defined by GCP services for platform logs. They have two components - a service namespace component and the attribute name. For example: compute.googleapis.com/resource_name.

Cloud Logging truncates label keys that exceed 512 B and label values that exceed 64 KB upon their associated log entry being written. The truncation is indicated by an ellipsis at the end of the character string.

Property Value
Type Description
MapFieldstringstring

LogName

public string LogName { get; set; }

Required. The resource name of the log to which this log entry belongs:

"projects/[PROJECT_ID]/logs/[LOG_ID]"
"organizations/[ORGANIZATION_ID]/logs/[LOG_ID]"
"billingAccounts/[BILLING_ACCOUNT_ID]/logs/[LOG_ID]"
"folders/[FOLDER_ID]/logs/[LOG_ID]"

A project number may be used in place of PROJECT_ID. The project number is translated to its corresponding PROJECT_ID internally and the log_name field will contain PROJECT_ID in queries and exports.

[LOG_ID] must be URL-encoded within log_name. Example: "organizations/1234567890/logs/cloudresourcemanager.googleapis.com%2Factivity".

[LOG_ID] must be less than 512 characters long and can only include the following characters: upper and lower case alphanumeric characters, forward-slash, underscore, hyphen, and period.

For backward compatibility, if log_name begins with a forward-slash, such as /projects/..., then the log entry is ingested as usual, but the forward-slash is removed. Listing the log entry will not show the leading slash and filtering for a log name with a leading slash will never return any results.

Property Value
Type Description
string

LogNameAsLogName

public LogName LogNameAsLogName { get; set; }

LogName-typed view over the LogName resource name property.

Property Value
Type Description
LogName

Operation

public LogEntryOperation Operation { get; set; }

Optional. Information about an operation associated with the log entry, if applicable.

Property Value
Type Description
LogEntryOperation

PayloadCase

public LogEntry.PayloadOneofCase PayloadCase { get; }
Property Value
Type Description
LogEntryPayloadOneofCase

ProtoPayload

public Any ProtoPayload { get; set; }

The log entry payload, represented as a protocol buffer. Some Google Cloud Platform services use this field for their log entry payloads.

The following protocol buffer types are supported; user-defined types are not supported:

"type.googleapis.com/google.cloud.audit.AuditLog" "type.googleapis.com/google.appengine.logging.v1.RequestLog"

Property Value
Type Description
Any

ReceiveTimestamp

public Timestamp ReceiveTimestamp { get; set; }

Output only. The time the log entry was received by Logging.

Property Value
Type Description
Timestamp

Resource

public MonitoredResource Resource { get; set; }

Required. The monitored resource that produced this log entry.

Example: a log entry that reports a database error would be associated with the monitored resource designating the particular database that reported the error.

Property Value
Type Description
MonitoredResource

Severity

public LogSeverity Severity { get; set; }

Optional. The severity of the log entry. The default value is LogSeverity.DEFAULT.

Property Value
Type Description
LogSeverity

SourceLocation

public LogEntrySourceLocation SourceLocation { get; set; }

Optional. Source code location information associated with the log entry, if any.

Property Value
Type Description
LogEntrySourceLocation

SpanId

public string SpanId { get; set; }

Optional. The ID of the Cloud Trace span associated with the current operation in which the log is being written. For example, if a span has the REST resource name of "projects/some-project/traces/some-trace/spans/some-span-id", then the span_id field is "some-span-id".

A Span represents a single operation within a trace. Whereas a trace may involve multiple different microservices running on multiple different machines, a span generally corresponds to a single logical operation being performed in a single instance of a microservice on one specific machine. Spans are the nodes within the tree that is a trace.

Applications that are instrumented for tracing will generally assign a new, unique span ID on each incoming request. It is also common to create and record additional spans corresponding to internal processing elements as well as issuing requests to dependencies.

The span ID is expected to be a 16-character, hexadecimal encoding of an 8-byte array and should not be zero. It should be unique within the trace and should, ideally, be generated in a manner that is uniformly random.

Example values:

  • 000000000000004a
  • 7a2190356c3fc94b
  • 0000f00300090021
  • d39223e101960076
Property Value
Type Description
string

Split

public LogSplit Split { get; set; }

Optional. Information indicating this LogEntry is part of a sequence of multiple log entries split from a single LogEntry.

Property Value
Type Description
LogSplit

TextPayload

public string TextPayload { get; set; }

The log entry payload, represented as a Unicode string (UTF-8).

Property Value
Type Description
string

Timestamp

public Timestamp Timestamp { get; set; }

Optional. The time the event described by the log entry occurred. This time is used to compute the log entry's age and to enforce the logs retention period. If this field is omitted in a new log entry, then Logging assigns it the current time. Timestamps have nanosecond accuracy, but trailing zeros in the fractional seconds might be omitted when the timestamp is displayed.

Incoming log entries must have timestamps that don't exceed the logs retention period in the past, and that don't exceed 24 hours in the future. Log entries outside those time boundaries aren't ingested by Logging.

Property Value
Type Description
Timestamp

Trace

public string Trace { get; set; }

Optional. The REST resource name of the trace being written to Cloud Trace in association with this log entry. For example, if your trace data is stored in the Cloud project "my-trace-project" and if the service that is creating the log entry receives a trace header that includes the trace ID "12345", then the service should use "projects/my-tracing-project/traces/12345".

The trace field provides the link between logs and traces. By using this field, you can navigate from a log entry to a trace.

Property Value
Type Description
string

TraceSampled

public bool TraceSampled { get; set; }

Optional. The sampling decision of the trace associated with the log entry.

True means that the trace resource name in the trace field was sampled for storage in a trace backend. False means that the trace was not sampled for storage when this log entry was written, or the sampling decision was unknown at the time. A non-sampled trace value is still useful as a request correlation identifier. The default is False.

Property Value
Type Description
bool
