Crash Summary Reference

Introduction

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

Contents

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. See this cookbook to get started working with the data in Spark.

s3://telemetry-parquet/crash_summary/v1/

crash_summary is accessible through re:dash. Here's an example query.

Further Reading

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

The code responsible for generating this dataset is here

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

Sampling

CrashSummary contains one record for every crash ping submitted by Firefox. It was built with the long term goal of providing a base for CrashAggregates.

Scheduling

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