Package logadmin contains a Cloud Logging client that can be used for reading logs and working with sinks, metrics and monitored resources. For a client that can write logs, see package cloud.google.com/go/logging.
The client uses Logging API v2. See https://cloud.google.com/logging/docs/api/v2/ for an introduction to the API.
Note: This package is in beta. Some backwards-incompatible changes may occur.
Client
type
Client
struct
{
// contains filtered or unexported fields
}
Client is a Logging client. A Client is associated with a single Cloud project.
func NewClient
func
NewClient
(
ctx
context
.
Context
,
parent
string
,
opts
...
option
.
ClientOption
)
(
*
Client
,
error
)
NewClient returns a new logging client associated with the provided project ID.
By default NewClient uses AdminScope. To use a different scope, call NewClient using a WithScopes option (see https://godoc.org/google.golang.org/api/option#WithScopes ).
Example
package
main
import
(
"context"
"cloud.google.com/go/logging/logadmin"
)

}
func (*Client) Close
Close closes the client.

UpdateSinkOpt updates an existing Sink, using the provided options. Requires AdminScope.
To change a sink's writer identity to a service account unique to the sink, set opts.UniqueWriterIdentity to true. It is not possible to change a sink's writer identity from a unique service account to a non-unique writer identity.
EntriesOption
type
EntriesOption
interface
{
// contains filtered or unexported methods
}
An EntriesOption is an option for listing log entries.
func Filter
func
Filter
(
f
string
)
EntriesOption
Filter sets an advanced logs filter for listing log entries (see https://cloud.google.com/logging/docs/view/advanced_filters ). The filter is compared against all log entries in the projects specified by ProjectIDs. Only entries that match the filter are retrieved. An empty filter (the default) matches all log entries.
In the filter string, log names must be written in their full form, as "projects/PROJECT-ID/logs/LOG-ID". Forward slashes in LOG-ID must be replaced by %2F before calling Filter.
Timestamps in the filter string must be written in RFC 3339 format. By default, timestamp filters for the past 24 hours.
Example
timestamp
package
main
import
(
"context"

Sink
type
Sink
struct
{
// ID is a client-assigned sink identifier. Example:
// "my-severe-errors-to-pubsub".
// Sink identifiers are limited to 1000 characters
// and can include only the following characters: A-Z, a-z,
// 0-9, and the special characters "_-.".
ID
string
// Destination is the export destination. See
// https://cloud.google.com/logging/docs/api/tasks/exporting-logs.
// Examples: "storage.googleapis.com/a-bucket",
// "bigquery.googleapis.com/projects/a-project-id/datasets/a-dataset".
Destination
string
// Filter optionally specifies an advanced logs filter (see
// https://cloud.google.com/logging/docs/view/advanced_filters) that
// defines the log entries to be exported. Example: "logName:syslog AND
// severity>=ERROR". If omitted, all entries are returned.
Filter
string
// WriterIdentity must be a service account name. When exporting logs, Logging
// adopts this identity for authorization. The export destination's owner must
// give this service account permission to write to the export destination.
WriterIdentity
string
// IncludeChildren, when set to true, allows the sink to export log entries from
// the organization or folder, plus (recursively) from any contained folders, billing
// accounts, or projects. IncludeChildren is false by default. You can use the sink's
// filter to choose log entries from specific projects, specific resource types, or
// specific named logs.
//
// Caution: If you enable this feature, your aggregated export sink might export
// a very large number of log entries. To avoid exporting too many log entries,
// design your aggregated export sink filter carefully, as described on
// https://cloud.google.com/logging/docs/export/aggregated_exports.
IncludeChildren
bool
}
Sink describes a sink used to export log entries outside Cloud Logging. Incoming log entries matching a filter are exported to a destination (a Cloud Storage bucket, BigQuery dataset or Cloud Pub/Sub topic).
For more information, see https://cloud.google.com/logging/docs/export/using_exported_logs . (The Sinks in this package are what the documentation refers to as "project sinks".)
SinkIterator
type
SinkIterator
struct
{
// contains filtered or unexported fields
}
A SinkIterator iterates over Sinks.
func (*SinkIterator) Next
func

Sink
,
error
)
Next returns the next result. Its second return value is Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

SinkOptions
type
SinkOptions
struct
{
// Determines the kind of IAM identity returned as WriterIdentity in the new
// sink. If this value is omitted or set to false, and if the sink's parent is a
// project, then the value returned as WriterIdentity is the same group or
// service account used by Cloud Logging before the addition of writer
// identities to the API. The sink's destination must be in the same project as
// the sink itself.
//
// If this field is set to true, or if the sink is owned by a non-project
// resource such as an organization, then the value of WriterIdentity will
// be a unique service account used only for exports from the new sink.
UniqueWriterIdentity
bool
// These fields apply only to UpdateSinkOpt calls. The corresponding sink field
// is updated if and only if the Update field is true.
UpdateDestination
bool
UpdateFilter
bool
UpdateIncludeChildren
bool
}
SinkOptions define options to be used when creating or updating a sink.
