Metrics and error reports are collected from devices in several ways: Cobalt, feedback reports, crash reports, manual reports from developers and QA. Interpreting these signals requires knowing where they are generated from to varying levels of detail. This document describes the places where version information about the system are stored for use in these types of reports.
Note that this information only applies to the base system; dynamically or ephemerally added software will not be included here.
View build information using CLI
To view the device's build information using a command line, run the following
ffx command:
ffx target showAccess build information at runtime
To access build information at runtime, use the
fuchsia.buildinfo.Provider
protocol capability in your
component manifest.
Typed build information is defined and documented in the
BuildInfo type. In addition, a jiri snapshot taken at
build time may be retrieved.
Lastly, the kernel version may be retrieved with
zx_system_get_version_string.
