Sample queries

This document provides you with suggested queries to make it easier to find important logs using the Logs Explorer in the Google Cloud console. The listed queries are written in the Logging query language, and they can be used in the Logs Explorer, the Logging API, or the command-line interface.

The Logs Explorer uses Boolean expressions to specify a subset of all the log entries in your project. You can use these queries to choose log entries from specific logs or log services, or that satisfy conditions on metadata or user-defined fields.

Before you begin

Ensure that you have the correct Identity and Access Management permissions or roles for building queries using the Logs Explorer. For details on the necessary IAM permissions, see Permissions for the Google Cloud console.

Get started

  1. In the Google Cloud console, go to the Logs Explorer page:

    Go to Logs Explorer

    If you use the search bar to find this page, then select the result whose subheading is Logging.

  2. Select the appropriate Google Cloud project or other Google Cloud resource for which you want to view logs.

Use the sample queries

To apply a query from the following tables, click the Content Copy icon for the expression, and then paste the copied expression into the Logs Explorer query-editor field.

The following screenshot illustrates the query pane:

The query editor is showing where to enter a query

If you don't see the query-editor field, enable Show query.

After you review your query expression, click Run query. Logs that match your query are listed under Query results.

Some of the queries listed later on this page include variables that you should replace with valid values. For example, when a query includes logName, then the PROJECT_ID you supply must refer to the selected Google Cloud project; otherwise, the query won't work.

Note the following:

  • If you have a query with a timestamp, then the time-range selector is disabled, and the query uses the timestamp expression as its time-range restriction. If a query doesn't use a timestamp expression, then the query uses the time-range selector as its time-range restriction.

  • The length of a query can't exceed 20,000 characters.

  • The Logging query language is case-insensitive, with the exception of regular expressions.

  • You can use the log_id function for queries with a log_name expression. For example, the expression log_name="projects/PROJECT_ID/logs/cloudaudit.googleapis.com%2Fdata_access" is the same as log_id("cloudaudit.googleapis.com/data_access"). For more information about the log_id function, see Logging query language: Functions.

For instructions about querying in the Google Cloud console, see Build queries in the Logs Explorer.

The following sections group queries by Google Cloud services.
