Trace Search
Trace search allows you to filter on spans of traces in your product based on a query, and allows you to see more information on
an overarching trace by clicking into a span. You can filter spans using a search query
For example, you can get to all spans of traces produced in the last 15 minutes from a private-graph service by selecting "Last
15 minutes" from the time picker and entering the following query:
service_name=private-graph
Searching for sessions
For general information on searching traces, check out our Search docs.
Default Key
The default key for trace search is span_name. If you enter an expression without a key (gorm.Query) it will be used as the
key for the expression (span_name=*gorm.Query*).
Searchable Attributes
You can search on any attributes that you send in your traces as well as any of the default attributes assigned to a trace. Our SDKs will also link sessions,errors, and logs to their respective traces.
The autoinjected attributes for traces can be seen in the table below.
| Attribute | Description | Example |
|---|---|---|
duration | Time length of the span in nanoseconds | 10s |
environment | The environment specified in the SDK | production |
has_errors | If the span has an error tied to its id | true |
highlight.type | More specific source of the span | http.request |
parent_span_id | Span id of the span's parent | 327611203ec5b0a1 |
secure_session_id | Session id that contains this span | wh1jcuN5F9G6Ra5CKeCjdIk6Rbyd |
service_name | Name of the service specified in the SDK | private-graph |
service_version | Version of the service specified in the SDK | e1845285cb360410aee05c61dd0cc57f85afe6da |
span_kind | Broad source of the span | Server |
span_name | Title of the span | POST https://app.highlight.io |
trace_id | Trace id of the spans | 7654ff38c4631d5a51b26f7e637eea3c |
You can view a full list of the available attributes to filter on by starting to type in the search box. As you type you'll get suggestions for keys to filter on.
Helpful Tips
To see all the spans of a specific trace, you can filter by trace_id to get a table view of the spans. You can also
click into the span to get more information, including a flame graph of the trace with all its spans.
Use secure_session_id EXISTS to only see spans that are tied to a session.
Use time suffixes, such as s, ms and us to help filter out for span durations. For example, use duration>1s to find
all spans that were longer than 1 second.
