All search parameters are contained in the url of the page, so it is very simple to share your view.
A query is composed of terms and operators.
There are two types of terms:
To combine multiple terms into a complex query, use any of the following boolean operators:
|Operator||**Description **||**Example **|
|Intersection: both terms are in the selected events (if nothing is added, AND is taken by default)||authentication AND failure|
|Union: either terms is contained in the selected events||authentication OR password|
|Exclusion: the following term is NOT in the event||authentication AND -password|
For instance, if your facet name is url and you want to filter on the url value www.datadoghq.com just enter:
Your traces inherit tags from hosts and integrations that generate them. They can be used in the search and as facets as well:
|All traces with the tag |
|All traces that contain tags |
|All traces that contain |
If your tags don’t follow tags best practices and don’t use the
key:value syntax, use this search query:
To perform a multi-character wildcard search, use the
* symbol as follows:
service:web*matches every trace that has a services starting with
@url:data*matches every trace that has a
>= to perform a search on numerical attributes. For instance, retrieve all traces that have a response time over 100ms with:
It is also possible to search for numerical attributes within a specific range. For instance, retrieve all your 4xx errors with:
@http.status_code:[400 TO 499]
Typing a complex query can be cumbersome. Use the search bar’s autocomplete feature to complete your query using existing values:
The following attributes are considered as special:
\ require escaping.
For instance, to search traces that contain
user=JaneDoe in their
url the following search must be entered:
The same logic must be applied to spaces within trace attributes. It is not recommended to have spaces in trace attributes but in such cases, spaces require escaping.
If an attribute is called
user.first name, perform a search on this attribute by escaping the space:
Don’t lose time building the same views everyday. Saved searches contain your search query, columns, and time horizon. They are then available in the search bar thanks to the auto-complete matching whether the search name or query.
To delete a saved search, click on the bin icon under the Trace search drop-down.
The time range allows you to display traces within a given time period. Quickly change the time range by selecting a preset range from the dropdown:
Sort the list by clicking the date column header.

A Facet displays all the distinct values of an attribute or a tag as well as provides some basic analytics such as the amount of traces represented. This is also a switch to easily filter your data.
Facets allow you to pivot or filter your datasets based on a given attribute. Examples Facets may include users, services, etc…
