NAME
gcloud logging read - read log entries
SYNOPSIS
gcloud logging read [LOG_FILTER] [--freshness=FRESHNESS; default="1d"] [--order=ORDER; default="desc"] [--billing-account=BILLING_ACCOUNT_ID     | --folder=FOLDER_ID     | --organization=ORGANIZATION_ID     | --project=PROJECT_ID] [--resource-names=[RESOURCE,…]     | --bucket=BUCKET --location=LOCATION --view=VIEW] [--limit=LIMIT] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
gcloud logging read reads log entries. Log entries matching log-filter are returned in order of decreasing timestamps, most-recent entries first. If the log entries come from multiple logs, then entries from different logs might be intermingled in the results.
EXAMPLES
To read log entries from Google Compute Engine instances, run: 
gcloud logging read "resource.type=gce_instance"

To read log entries with severity ERROR or higher, run: 

gcloud logging read "severity>=ERROR"

To read log entries written in a specific time window, run: 

gcloud logging read 'timestamp<="2015-05-31T23:59:59Z" AND
 timestamp>="2015-05-31T00:00:00Z"'

To read up to 10 log entries in your project's syslog log from Compute Engine instances containing payloads that include the word SyncAddress and format the output in JSON format, run: 

gcloud logging read "resource.type=gce_instance AND logName=projects/[PROJECT_ID]/logs/syslog AND textPayload:SyncAddress" --limit=10 --format=json

To read a log entry from a folder, run: 

gcloud logging read "resource.type=global" --folder=[FOLDER_ID] --limit=1

To read a log entry from a global log bucket, run: 

gcloud logging read --bucket=<bucket-id> --location=[LOCATION] --limit=1

To read a log entry from the global _Required log bucket using the bucket's _Default log view: 

gcloud logging read "" --bucket=_Required --location=global --view=_Default --limit=1

To read a log entry from a log bucket using the bucket's _AllLogs log view: 

gcloud logging read "" --bucket=[BUCKET_ID] --location=[LOCATION] --view=_AllLogs --limit=1

To read a log entry from a log bucket using a custom log view that you have created for the bucket: 

gcloud logging read "" --bucket=[BUCKET_ID] --location=[LOCATION] --view=[VIEW_ID] --limit=1

To read log entries from multiple resources, specify them as a comma-delimeted sequence with --resource-names. Each resource name can be specified either as a top-level resource (e.g., projects/[PROJECT_ID], folders/[FOLDER_ID], etc.) or as a Log View resource (e.g., projects/[PROJECT_ID]/locations/[LOCATION]/buckets/[BUCKET_NAME]/views/[VIEW_ID]). 

gcloud logging read "" --resource-names=[RESOURCE-1],[RESOURCE-2]
POSITIONAL ARGUMENTS
[LOG_FILTER]
Filter expression that specifies the log entries to return. Detailed information about filters can be found at: https://cloud.google.com/logging/docs/view/logging-query-language
FLAGS
--freshness=FRESHNESS; default="1d"
Return entries that are not older than this value. Works only with DESC ordering and filters without a timestamp. See $ gcloud topic datetimes for information on duration formats.
--order=ORDER; default="desc"
Ordering of returned log entries based on timestamp field. ORDER must be one of: desc, asc.
At most one of these can be specified:
--billing-account=BILLING_ACCOUNT_ID
Billing account of the log entries to read.
--folder=FOLDER_ID
Folder of the log entries to read.
--organization=ORGANIZATION_ID
Organization of the log entries to read.
--project=PROJECT_ID
Project of the log entries to read.

The Google Cloud project ID to use for this invocation. If omitted, then the current project is assumed; the current project can be listed using gcloud config list --format='text(core.project)' and can be set using gcloud config set project PROJECTID.

--project and its fallback core/project property play two roles in the invocation. It specifies the project of the resource to operate on. It also specifies the project for API enablement check, quota, and billing. To specify a different project for quota and billing, use --billing-project or billing/quota_project property. At most one of these can be specified:
--resource-names=[RESOURCE,…]
Resource name(s) to read logs from. A resource can either be an top-level resource (e.g., "projects/my-project") or a full log view resource path (e.g., "projects/my-project/locations/my-location/buckets/my-bucket/views/my-view"). Multiple resources can be specified, separated by a comma.
Or at least one of these can be specified: These arguments are used in conjunction with the parent to construct a view resource.
--bucket=BUCKET
Id of the log bucket. If this argument is provided then --location and --view must also be specified. This flag argument must be specified if any of the other arguments in this group are specified.
--location=LOCATION
Location of the log bucket. If this argument is provided then --bucket and --view must also be specified. This flag argument must be specified if any of the other arguments in this group are specified.
--view=VIEW
Id of the view. If this argument is provided then --location and --bucket must also be specified. This flag argument must be specified if any of the other arguments in this group are specified.
LIST COMMAND FLAGS
--limit=LIMIT
Maximum number of resources to list. The default is unlimited. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.
GCLOUD WIDE FLAGS
These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.

Run $ gcloud help for details.
