Errors
editErrors
editAn error event contains at least
information about the original exception that occurred
or about a log created when the exception occurred.
For simplicity, errors are represented by a unique ID.
An Error contains:
-
Both the captured
exceptionand the capturedlogof an error can contain astack trace, which is helpful for debugging. -
The
culpritof an error indicates where it originated. -
An error might relate to the transaction during which it happened,
via the
transaction.id. -
Data about the environment in which the event is recorded:
- Service - environment, framework, language, etc.
- Host - architecture, hostname, IP, etc.
- Process - args, PID, PPID, etc.
- URL - full, domain, port, query, etc.
- User - (if supplied) email, ID, username, etc.
In addition, agents provide options for users to capture custom metadata.
Metadata can be indexed - labels, or not-indexed - custom.
Most agents limit keyword fields (e.g. error.id) to 1024 characters,
non-keyword fields (e.g. error.exception.message) to 10,000 characters.
Errors are stored in error indices.
Data streams
editErrors are stored in the following data streams:
-
APM error/exception logging:
logs-apm.error-<namespace>
See Data streams to learn more.
Example error document
editThis example shows what error documents can look like when indexed in Elasticsearch.
