class="devsite-article-body clearfix "> <p>This document explains how Cloud Logging processes log entries, and describes the key components of Logging routing and storage. <em>Routing</em> refers to the process that Cloud Logging uses to determine what to do with a newly-arrived log entry. You can route log entries to destinations like Logging buckets, which store the log entry, or to Pub/Sub. To export your logs into third-party destinations, route your logs to a Pub/Sub topic, and then authorize the third-party destination to subscribe to the Pub/Sub topic.</p> <p>At a high level, this is how Cloud Logging routes and stores log entries:</p> <p><img src="/static/logging/docs/images/routing-overview.png" alt="Figure illustrating how Cloud Logging routes logs entries."></p> <h2 id="ingesting-routing" data-text="Route logs with the Log Router" tabindex="-1">Route logs with the Log Router</h2> <p>The following sections explain how Logging routes logs with the Log Router by using sinks.</p> <h3 id="log-router" data-text="Log Router" tabindex="-1">Log Router</h3> <p>A log entry is sent to the <a href="/resource-manager/docs/cloud-platform-resource-hierarchy#resource-hierarchy-detail">Google Cloud resource</a> specified in its <a href="/logging/docs/reference/v2/rest/v2/LogEntry"><code translate="no" dir="ltr">logName</code></a> field during its <a href="/logging/docs/reference/v2/rest/v2/entries/write"><code translate="no" dir="ltr">entries.write</code></a> call.</p> <p>Cloud Logging receives log entries with the <a href="/logging/docs/reference/api-overview">Cloud Logging API</a> where they pass through the Log Router. The <a href="#sinks">sinks</a> in the Log Router check each log entry against their <a href="#inclusion-filters">inclusion filter</a> and <a href="#exclusions">exclusion filters</a>, and then determine which destinations, including Cloud Logging buckets, that the log entry should be sent to. You can use combinations of sinks to route a log entry to multiple destinations.</p> <p>The Log Router stores the log entry temporarily. This behavior buffers against temporary disruptions and outages that might occur when a sink routes a log entry to a destination. The buffering doesn't protect against sink configuration errors. If your sink is configured incorrectly, then it doesn't route log entries, an error log is generated, and an email notifying you of a sink configuration error is sent. When log entries can't be routed, they are discarded.</p> <p>The Log Router's temporary storage is distinct from the longer term storage provided by Logging buckets.</p> <p>Incoming log entries with timestamps that are more than the <a href="/logging/quotas#logs_retention_periods">logs retention period</a> in the past or that are more than 24 hours in the future are discarded.</p> <h3 id="sinks" data-text="Sinks" tabindex="-1">Sinks</h3> <p>Sinks control how Cloud Logging routes logs. Using sinks, you can route some or all of your logs to <a href="#destinations">supported destinations</a>. Some of the reasons that you might want to control how your logs are routed include the following:</p> <ul> <li>To store logs that are unlikely to be read but that must be retained for compliance purposes.</li> <li>To organize your logs in buckets in a format that is useful to you.</li> <li>To use big-data analysis tools on your logs.</li> <li>To stream your logs to other applications, other repositories, or third parties. For example, if you want to export your logs from Google Cloud so that you can view them on a third-party platform, then configure a sink to route your log entries to Pub/Sub.</li> </ul> <p>Sinks belong to a given Google Cloud resource: Google Cloud projects, billing accounts, folders, and organizations. When the resource receives a log entry, it routes the log entry according to the sinks contained by that resource and, if enabled, any ancestral sinks belonging under the <a href="/resource-manager/docs/cloud-platform-resource-hierarchy#resource-hierarchy-detail">resource hierarchy</a>. The log entry is sent to the destination associated with each matching sink.</p> <p>Cloud Logging provides two predefined sinks for each Google Cloud project, billing account, folder, and organization: <code translate="no" dir="ltr">_Required</code> and <code translate="no" dir="ltr">_Default</code>. All logs that are generated in a resource are automatically processed through these two sinks and then are stored either in the correspondingly named <a href="#required-bucket"><code translate="no" dir="ltr">_Required</code></a> or <a href="#default-bucket"><code translate="no" dir="ltr">_Default</code></a> buckets.</p> <p>Sinks act independently of each other. Regardless of how the predefined sinks process your log entries, you can create your own sinks to route some or all of your logs to various <a href="#destinations">supported destinations</a> or to exclude them from being stored by Cloud Logging.</p> <p>Which log entries are routed by a sink is controlled by configuring the sink's <a href="#inclusion-filters">inclusion filter</a> and <a href="#exclusions">exclusion filters</a>. Depending on the sink's configuration, every log entry received by Cloud Logging falls into one or more of these categories:</p> <ul> <li><p>Stored in Cloud Logging and not routed elsewhere.</p></li> <li><p>Stored in Cloud Logging and routed to a supported destination.</p></li> <li><p>Not stored in Cloud Logging but routed to a supported destination.</p></li> <li><p>Neither stored in Cloud Logging nor routed elsewhere.</p></li> </ul> <p>You usually <a href="/logging/docs/export/configure_export_v2">create sinks</a> at the Google Cloud project level, but if you want to combine and route logs from the resources contained by a Google Cloud organization or folder, you can create <a href="/logging/docs/export/aggregated_sinks">aggregated sinks</a>.</p> <p>Sinks only route log entries that arrive after the sink is created because routing happens as logs pass through the Logging API. If you need to route log entries retroactively, see <a href="/logging/docs/routing/copy-logs">Copy logs</a>. <h3 id="inclusion-filters" data-text="Inclusion filters" tabindex="-1">Inclusion filters</h3> <p>When a sink doesn't specify any filters, all log entries match and are routed to the sink's destination. You can configure the sink to select specific log entries by setting an inclusion filter. You can also set one or more <a href="#exclusions">exclusion filters</a> to exclude log entries from being routed.</p> <p>When you <a href="/logging/docs/export/configure_export_v2">configure a sink</a>, you specify its filters by using the <a href="/logging/docs/view/logging-query-language">Logging query language</a>.</p> <p>A log entry is routed by a sink based on these rules:</p> <ul> <li><p>If the log entry doesn't match the inclusion filter, then it isn't routed. When a sink doesn't specify an inclusion filter, then every log entry matches that filter.</p></li> <li><p>If the log entry matches the inclusion filter and at least one exclusion filter, then it isn't routed.</p></li> <li><p>If the log entry matches the inclusion filter and doesn't match any exclusion filter, then it is routed to the sink's destination.</p></li> </ul> <h3 id="exclusions" data-text="Exclusion filters" tabindex="-1">Exclusion filters</h3> <p>When you <a href="/logging/docs/export/configure_export_v2">create a sink</a>, you can set multiple exclusion filters. Exclusion filters let you exclude log entries that match the inclusion filter from being routed to the sink's destination or from being stored in a log bucket. You define exclusion filters by using the <a href="/logging/docs/view/logging-query-language">Logging query language</a>.</p> <p>Excluded log entries consume <a href="/logging/quotas#api-limits"><code translate="no" dir="ltr">entries.write</code> API quota</a> because they are excluded after they are received by the Logging API. You can't reduce the number of <a href="/logging/quotas#log-limits"><code translate="no" dir="ltr">entries.write</code> API calls</a> by excluding log entries.</p> <p>Excluded log entries aren't available in the Logs Explorer.</p> Log entries that aren't routed to at least one log bucket, either explicitly with exclusion filters or because they don't match any sinks with a Logging storage destination, are also excluded from Error Reporting. Therefore, these log entries aren't available to help troubleshoot failures. User-defined log-based metrics are computed from log entries in both included and excluded log entries. For more information, see <a href="/logging/docs/alerting/monitoring-logs#which-logs">Monitor your logs</a>. <h3 id="destinations" data-text="Supported destinations" tabindex="-1">Supported destinations</h3> <p>You can use the Log Router to route certain log entries to supported destinations in any Google Cloud project. Logging supports the following sink destinations:</p> <ul> <li><p><em>Cloud Logging bucket</em>: Provides storage in Cloud Logging. A <a href="/logging/docs/routing/overview#buckets">log bucket</a> can store log entries that are received by multiple Google Cloud projects. The log bucket can be in the same project in which log entries originate, or in a different project. For information about viewing log entries stored in log buckets, see <a href="/logging/docs/log-analytics">Query and view logs overview</a> and <a href="/logging/docs/export/using_exported_logs">View logs routed to Cloud Logging buckets</a>.</p> <p>You can combine your Cloud Logging data with other data by upgrading a log bucket to use Log Analytics, and then creating a linked dataset, which is a read-only dataset that can be queried by the <strong>BigQuery Studio</strong> and <strong>Looker Studio</strong> pages.</p> </li> </ul> <ul> <li><p><em>BigQuery dataset</em>: Provides storage of log entries in a writeable BigQuery dataset. The BigQuery dataset can be in the same project in which log entries originate, or in a different project. You can use big data analysis capabilities on the stored log entries. For information about viewing log entries routed to BigQuery, see <a href="/logging/docs/export/bigquery">View logs routed to BigQuery</a>.</p> <aside class="note"><strong>Note:</strong><span> Linked BigQuery datasets are read-only. These datasets can't be used as a sink destination.</span></aside></li> </ul> <ul> <li><em>Cloud Storage bucket</em>: Provides storage of log entries in Cloud Storage. The Cloud Storage bucket can be in the same project in which log entries originate, or in a different project. Log entries are stored as JSON files. For information about viewing log entries routed to Cloud Storage, see <a href="/logging/docs/export/storage">View logs routed to Cloud Storage</a>.</li> </ul> <ul> <li><p><em>Pub/Sub topic</em>: Provides support for third-party integrations. Log entries are formatted into JSON and then routed to a Pub/Sub topic. The topic can be in the same project in which log entries originate, or in a different project. For information about viewing log entries routed to Pub/Sub, see <a href="/logging/docs/export/pubsub">View logs routed to Pub/Sub</a>.</p></li> <li><p><em>Google Cloud project</em>: Route log entries to another Google Cloud project. In this configuration, the sinks in the destination project processes the log entries.</p></li> </ul> <p>For more information, see <a href="/logging/docs/export/configure_export_v2">Route logs to supported destinations</a>.</p> <h2 id="storing" data-text="Storing, viewing, and managing logs" tabindex="-1">Storing, viewing, and managing logs</h2> <p>The following section details how logs are stored in Cloud Logging, and how you can view and manage them.</p> <h3 id="buckets" data-text="Log buckets" tabindex="-1">Log buckets</h3> <p>Cloud Logging uses log buckets as containers in your Google Cloud projects, billing accounts, folders, and organizations to store and organize your logs data. The log entries that you store in Cloud Logging are indexed, optimized, and delivered to let you analyze your logs in real time. Cloud Logging buckets are different storage entities than the similarly named Cloud Storage buckets. <p>For each Google Cloud project, billing account, folder, and organization, Logging automatically creates two log buckets: <code translate="no" dir="ltr">_Required</code> and <code translate="no" dir="ltr">_Default</code>. Logging automatically creates sinks named <code translate="no" dir="ltr">_Required</code> and <code translate="no" dir="ltr">_Default</code> that, in the default configuration, route log entries to the correspondingly named buckets.</p> <p>You can disable the <code translate="no" dir="ltr">_Default</code> sink, which routes log entries to the <code translate="no" dir="ltr">_Default</code> log bucket. You can also change the behavior of the <code translate="no" dir="ltr">_Default</code> sinks created for any new Google Cloud projects or folders. For more information, see <a href="/logging/docs/default-settings">Configure default settings for organizations and folders</a>.</p> <p>You can't change routing rules for the <code translate="no" dir="ltr">_Required</code> bucket.</p> <p>Additionally, you can create <a href="#user-buckets">user-defined buckets</a> for any Google Cloud project.</p> <p>You create sinks to route all, or just a subset, of your log entries to any log bucket. This flexibility lets you choose the Google Cloud project in which your log entries are stored, and lets you store log entries from multiple resources in one location.</p> <p>For more information, see <a href="/logging/docs/buckets">Configure log buckets</a>.</p> <h4 id="required-bucket" data-text="_Required log bucket" tabindex="-1"><code translate="no" dir="ltr">_Required</code> log bucket</h4> <p>Cloud Logging automatically routes the following types of log entries to the <code translate="no" dir="ltr">_Required</code> bucket:</p> <ul> <li><a href="/logging/docs/audit#admin-activity">Admin Activity audit logs</a></li> <li><a href="/logging/docs/audit#system-event">System Event audit logs</a></li> <li>Google Workspace Admin Audit logs</li> <li>Enterprise Groups Audit logs</li> <li>Login Audit logs</li> </ul> <ul> <li>Access Transparency logs.
