Crash Summary Reference


As of 2019-11-06, this dataset has been deprecated and is no longer maintained. Please use the telemetry.crash table instead, which is generated directly from live pings and is much more complete. See Bug 1572069 for more information.

The crash_summary table is the a direct representation of a crash ping.


The crash_summary table contains one row for each crash ping. Each column represents one field from the crash ping payload, though only a subset of all crash ping fields are included.

Accessing the Data

The data is stored as a parquet table in S3 at the following address.


crash_summary is accessible through STMO. Here's an example query (STMO#4793).

Further Reading

The technical documentation for crash_summary is located in the telemetry-batch-view documentation.

Example Queries

Here is an example query to get the total number of main crashes by gfx_compositor:

select gfx_compositor, count(*)
from crash_summary
where application = 'Firefox'
and (payload.processType IS NULL OR payload.processType = 'main')
group by gfx_compositor


CrashSummary contains one record for every crash ping submitted by Firefox.


This dataset is updated daily, shortly after midnight UTC. The job is scheduled on telemetry-airflow. The DAG is here.
