Discover the query

Discover provides visibility into your data across environments by building and enriching your error data. You can query and unlock insights into the health of the entire system and get answers to key business questions in one place.

The Discover home page provides a view of all saved and pre-built queries, so you can quickly drill down to areas that need immediate attention. For example, if there is a spike in error queries in the last 24 hours, the user can investigate first. Each query is saved as a card that shows a summary view of the data.

The chart snapshot
Date range
The last edit

Preset query

Query cards with Sentry ICONS are pre-built and cannot be removed.

All Events: Users can view the raw error stream for any project team. This replaces the event function, enabling the user to add additional columns and change the grouping to achieve the desired refinement.
Errors by Title: Users can view the most common errors by looking at the total number of original errors and the total number of users affected.
Errors by URL: The user can see the page that produces the most errors and different types of problems. As a reminder, the problem is a set of fingerprint events. See the complete documentation on fingerprints for more details.

Saved query

A query card with the user’s profile picture represents a saved query. Users who create a saved query will have their profile picture displayed on the query card. The saved queries are viewable by anyone in the organization and are not limited to user accounts.

Building a new query

From the Discover home page, you can build queries in three ways.

Click on theBuild a new Query
Click the ellipsis of an existing saved query card toDuplicate (copy)
Enter any existing query
1. Click on the top rightSave as...
2. Enter display name
3. Click on theSave (Save)

Apply new search criteria or table columns to modify query results. Save the query and assign a custom display name. See the documentation on query generators for complete details.

Docs. Sentry. IO/product/dis…

A search query

Looking for a specific query? Use the search bar on the home page to find the query name.

Sorting query

A drop-down menu in the upper right corner will allow you to sort by property.

Recent editorRecently Edited(the default)
I queryMy Queries
The name of the queryQuery Name (A-Z)
Creation dateDate Created(latest)
Creation dateDate Created(the oldest)
The most out of dateMost Outdated

Edit the query

If you need to edit any of these queries, go into the query and make the required changes, and a button appears in the upper right corner asking you to save/update the query. Keep in mind that edits to query criteria are not automatically saved.

To rename a saved query, click the pencil icon next to the title and enter the desired display name. Click Enter or click outside the area to save the updated name.

Share the query

Feel free to share your questions. You can share urls with other users who also have access to the same organization. As each part of the query is built, the results and URLS are updated so that ongoing searches can be shared in E-mail, chat, and so on.

Delete query

On the Discover home page, each saved query card has an ellipsis that opens the context menu. From here, you can delete the query. This action is irreversible. You can also delete the Query in the Query Results view by clicking the trash can in the upper right corner.

The query results

To see the query results, click on any query card. You’ll find charts, tables, and switchable label summaries (or facet maps). The search bar at the top lets you see the search criteria you entered. This table represents events that have a sortable sequence.

Each table cell has a dynamic context menu that allows you to continue exploring your data by automatically updating the search bar or table column as you choose. Actions such as adding or excluding values in filters, opening the selected version, or viewing the underlying problem stack:

If the first column displays an icon (as shown above), the event is stacked. Click the icon for a complete list of events. Each event has an event ID, which you can click to learn more about. For more information on how to build queries, go to query Builder.

Docs. Sentry. IO/product/dis…

Event details

Navigate to the Event details page from Discover > [Saved Query] > Event Detail. You will find all relevant details about a single event. For each event, you see the ID, timestamp, and link to see the normalized JSON payload received by Sentry.

The Event Detail view varies by Event type (error, transaction, CSP). Transaction event details may have a completely different view from error event details (as shown above). For example, errors might show up in the sidebar. This allows you to quickly browse the volume of events for the issue and lets you quickly navigate to related issues. You can also find stack traces, breadcrumbs, and more in these views.

Query generator

From the Discover home page, you can build queries in three ways.

Click on theBuild a new Query
Click the ellipsis of an existing saved query card toDuplicate (copy)
Enter any existing query
1. Click on the top rightSave as...
2. Enter display name
3. Click on theSave (Save)

There are four main building blocks that affect the results of saved queries. You can use a combination of these methods to narrow your search.

Global Selection Header
Search Conditions
An Interactive Graph
Table Columns

Filter by globally selected title

Specify the projects, Environments, and date range to zoom in on at the top of the page. This can also be found in other parts of the Sentry as a Top level filter.

Filter by search criteria

All events have built-in key fields or custom tags. Use the search bar to enter these keys and assign them values. This will filter your list of events. This is the key fields built in.


General (common)	`id` (string) `issue.id` (number) `message` (string) `project.id` (number) `release` (string) `release.package` (string) `release.version` (string) `release.build` (string) `title` (string) `platform.name` (string) `environment` (string) `event.type`(string) `location` (string) `timestamp` (datetime) `timestamp.to_hour` (datetime) `timestamp.to_day` (datetime)
Device (equipment)	`device.arch` (string) `device.battery_level` (number) `device.brand` (string) `device.charging` (string) `device.locale` (string) `device.name` (string) `device.online` (string) `device.orientation` (string) `device.simulator` (string) `device.uuid` (string)
Geo (geography)	`geo.city` (string) `geo.country_code` (string) `geo.region` (string)
HTTP	`http.method` (string) `http.url` (string)
OS	`os.build` (string) `os.kernel_version` (string)
SDK	`sdk.name` (string) `sdk.version` (string)
Stack traces	`error.handled` (string) `error.mechanism` (string) `error.type` (string) `error.value` (string) `stack.abs_path` (string) `stack.colno` (number) `stack.filename` (string) `stack.function` (string) `stack.in_app` (boolean) `stack.lineno` (number) `stack.module` (string) `stack.package` (string) `stack.stack_level` (number)
User Attributes	`user` (string) `user.email` (string) `user.id` (string) `user.ip` (string) `user.username` (string)

grammar

The query generator syntax is the same as Sentry’s search syntax. After entering key fields or custom tags from above, you can use any referenced syntax. For example, count() gives you the number of times the event occurred. This can be written as follows:

A perfect match (equal to) :count():99
Upper limit (less than or equal to) :count():<99 或 count():<=99
Lower limit (greater than or equal to) :count():>99 或 count():>=99
Multiple boundaries (greater than and less than) :count():>10 count():<20

Use OR AND AND search criteria between filters. However, OR cannot be used between aggregate and non-aggregate filters. For more details on these conditions, see Using OR AND.

Docs. Sentry. IO/product/sen…

You can also search for multiple values of the same key by placing values in a list. For example, “x:[value1, value2]” will find the same result as “x:value1 OR x:value2”. You can learn more about this in our coverage of multiple values on the same Key.

Docs. Sentry. IO/product/sen…

Tag the Summary filter

Each event has a list of tag values. The label Summary facet chart (or facet chart) is a visualization of the top 10 keys sorted by frequency. The most common tag values are listed directly above the description and percentage columns. Hover over each section of the bar to see the exact distribution of the label.

Click on any of these sections to further refine your search. For example, clicking on the part of the browser bar that represents Chrome will automatically update the Tag summary and then add Chrome to the search criteria.

Filter by interactive chart

Each query has an interactive chart that reflects the data displayed in the table below. To zoom in, simply click and drag on the area you want to survey. You can also customize the display and Y axis. This will be saved with your query.

Filter by table

At the top of the table, click Columns to turn on Modal. This displays a list of all the columns in the result table. You can add, remove, and move basic Key Field columns or Custom Tags columns. Using the same view, you can also stack events using any of the following functions:

Overlay function

avg(...)
count(...)
count_unique(...)
max(...)
min(...)
sum(...)

Each function asks you to assign a parameter. Some are required, while others are optional. The function will stack events based on the same values. If no function is applied, the events in the query result are listed separately. After the columns are edited, click Apply. The query results are reflected in the query results. Keep in mind that if you add too many columns, the table may scroll horizontally.

Cell filtering

Each cell in the table appears with an ellipsis as it hovers. This opens a context menu with additional filtering capabilities depending on the value type. For example, you can selectively locate a transaction to the search criteria bar by clicking Add to Filter.

Additive equation

You can also add equations to the query using table columns as equation variables, and the results will be displayed in the query results table. Learn more in adding query equations.

Row of the sequence

Click the column header that you want to sort. The down arrow sorts the columns in descending order, and the up arrow sorts the columns in ascending order. This may refresh the table.
