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. For more information about querying, go to
Building queries.
Getting started
To navigate to the Logs Explorer, do the following:
Go to the Google Cloud navigation menu menu and
select Logging > Logs Explorer: Go to the Logs Explorer
Select a Google Cloud project.
From the Upgrade menu, switch from
Legacy Logs Viewer to Logs Explorer.
You're now in the Logs Explorer.
Using the sample queries
To apply a query from the following tables, copy an expression by clicking the
clipboard icon file_copy at
the end of any expression's row and then paste the copied expression into
the Query builder text box:
After you enter your 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 (indicated by
brackets []) that you should replace with valid values. For example, when a
query includes logName, then the [PROJECT_ID] you supply must refer
to the currently selected Google Cloud project; otherwise, the query
won't work. For more information, go to
Troubleshooting.
The following sections group queries by Google Cloud services.
