Overview
Error Tracking intelligently groups similar errors into issues with a default strategy. By using custom fingerprinting, you can gain full control over the grouping decision and customize the grouping behavior for your error spans.
Provide an error.fingerprint span tag that Error Tracking can use to group error spans into issues. While the value of the error.fingerprint attribute does not have any particular format or requirement, the content must be a string.
If error.fingerprint is provided, the grouping behavior follows these rules:
- Custom grouping takes precedence over the default strategy.
- Custom grouping can be applied only to a subset of your error spans and can co-exist with the default strategy.
- The content of
error.fingerprint is used as-is without any modification. - Spans from the same service and with the same
error.fingerprint attribute are grouped into the same issue. - Spans with different
service attributes are grouped into different issues.
Setup
Custom grouping only needs an error span and an error.fingerprint string span tag.
If you aren’t already collecting APM traces with Datadog, see the APM documentation to set up APM.
Example
If you’re already sending APM spans, add a new error.fingerprint tag to your error span.
Here’s an example in Python:
with tracer.trace("throws.an.error") as span:
span.set_tag('error.fingerprint', 'my-custom-grouping-material')
raise Exception("Something went wrong")
Exception information is captured and attached to a span if there is one active when the exception is raised.
In this case, my-custom-grouping-material is used to group these error spans into a single
issue in Error Tracking.
