-# crash_reporter
-
-`crash_reporter` is a deamon running on the device that saves the call stack of
-crashing programs. It makes use of the
-[Breakpad](https://chromium.googlesource.com/breakpad/breakpad/) library.
-
-During a build, Breakpad symbol files are generated for all binaries.  They are
-packaged into a zip file when running `m dist`, so that a developer can upload
-them to the crash server.
-
-On a device, if the user has opted in to metrics and crash reporting, a
-Breakpad minidump is generated when an executable crashes, which is then
-uploaded to the crash server.
-
-On the crash server, it compares the minidump's signature to the symbol files
-that the developer has uploaded, and extracts and symbolizes the stack trace
-from the minidump.
-
-## SELinux policies
-
-In order to correctly generate a minidump, `crash_reporter` needs to be given
-the proper SELinux permissions for accessing the domain of the crashing
-executable.  By default, `crash_reporter` has only been given access to a select
-number of system domains, such as `metricsd`, `weave`, and `update_engine`.  If
-a developer wants their executable's crashes to be caught by `crash_reporter`,
-they will have to set their SELinux policies in their .te file to allow
-`crash_reporter` access to their domain.  This can be done through a simple
-[macro](https://android.googlesource.com/device/generic/brillo/+/master/sepolicy/te_macros):
-
-    allow_crash_reporter(domain_name)
-
-Replace *domain_name* with whatever domain is assigned to the executable in
-the `file_contexts` file.
-
-## Configuration
-
-`crash_reporter` has a few different configuration options that have to be set.
-
-- Crashes are only handled and uploaded if analytics reporting is enabled,
-  either via the weave call to set `_metrics.enableAnalyticsReporting` or by
-  manually creating the file `/data/misc/metrics/enabled` (for testing only).
-- The `BRILLO_CRASH_SERVER` make variable should be set in the `product.mk`
-  file to the URL of the crash server.  For Brillo builds, it is set
-  automatically through the product configuration.  Setting this variable will
-  populate the `/etc/os-release.d/crash_server` file on the device, which is
-  read by `crash_sender`.
-- The `BRILLO_PRODUCT_ID` make variable should be set in the `product.mk` file
-  to the product's ID.  For Brillo builds, it is set automatically through the
-  product configuration.  Setting this variable will populate the
-  `/etc/os-release.d/product_id`, which is read by `crash_sender`.
-
-## Uploading crash reports in *eng* builds
-
-By default, crash reports are only uploaded to the server for production
-*user* and *userdebug* images.  In *eng* builds, with crash reporting enabled
-the device will generate minidumps for any crashing executables but will not
-send them to the crash server.  If a developer does want to force an upload,
-they can do so by issuing the command `SECONDS_SEND_SPREAD=5 FORCE_OFFICIAL=1
-crash_sender` from an ADB shell.  This will send the report to the server, with
-the *image_type* field set to *force-official* so that these reports can be
-differentiated from normal reports.

-Metricsd
-========
-
-The metricsd daemon is used to gather metrics from the platform and application,
-aggregate them and upload them periodically to a server.
-The metrics will then be available in their aggregated form to the developer
-for analysis.
-
-Three components are provided to interact with `metricsd`: `libmetrics`,
-`metrics_collector` and `metrics_client`.
-
-The Metrics Library: libmetrics
--------------------------------
-
-`libmetrics` is a small library that implements the basic C++ API for
-metrics collection. All metrics collection is funneled through this library. The
-easiest and recommended way for a client-side module to collect user metrics is
-to link `libmetrics` and use its APIs to send metrics to `metricsd` for transport to
-UMA. In order to use the library in a module, you need to do the following:
-
-- Add a dependency on the shared library in your Android.mk file:
-  `LOCAL_SHARED_LIBRARIES += libmetrics`
-
-- To access the metrics library API in the module, include the
-  <metrics/metrics_library.h> header file.
-
-- The API is documented in `metrics_library.h`. Before using the API methods, a
-  MetricsLibrary object needs to be constructed and initialized through its
-  Init method.
-
-- Samples are uploaded only if the `/data/misc/metrics/enabled` file exists.
-
-
-Server Side
------------
-
-You will be able to see all uploaded metrics on the metrics dashboard,
-accessible via the developer console.
-
-*** note
-It usually takes a day for metrics to be available on the dashboard.
-***
-
-
-The Metrics Client: metrics_client
-----------------------------------
-
-`metrics_client` is a simple shell command-line utility for sending histogram
-samples and querying `metricsd`. It's installed under `/system/bin` on the target
-platform and uses `libmetrics`.
-
-For usage information and command-line options, run `metrics_client` on the
-target platform or look for "Usage:" in `metrics_client.cc`.
-
-
-The Metrics Daemon: metricsd
-----------------------------
-
-`metricsd` is the daemon that listens for metrics logging calls (via Binder),
-aggregates the metrics and uploads them periodically. This daemon should start as
-early as possible so that depending daemons can log at any time.
-
-`metricsd` is made of two threads that work as follows:
-
-* The binder thread listens for one-way Binder calls, aggregates the metrics in
-  memory (via `base::StatisticsRecorder`) and increments the crash counters when a
-  crash is reported. This thread is kept as simple as possible to ensure the
-  maximum throughput possible.
-* The uploader thread takes care of backing up the metrics to disk periodically
-  (to avoid losing metrics on crashes), collecting metadata about the client
-  (version number, channel, etc..) and uploading the metrics periodically to the
-  server.
-
-
-The Metrics Collector: metrics_collector
-----------------------------------------
-
-metrics_collector is a daemon that runs in the background on the target platform,
-gathers health information about the system and maintains long running counters
-(ex: number of crashes per week).
-
-The recommended way to generate metrics data from a module is to link and use
-libmetrics directly. However, we may not want to add a dependency on libmetrics
-to some modules (ex: kernel). In this case, we can add a collector to
-metrics_collector that will, for example, take measurements and report them
-periodically to metricsd (this is the case for the disk utilization histogram).
-
-
-FAQ
----
-
-### What should my histogram's |min| and |max| values be set at?
-
-You should set the values to a range that covers the vast majority of samples
-that would appear in the field. Note that samples below the |min| will still
-be collected in the underflow bucket and samples above the |max| will end up
-in the overflow bucket. Also, the reported mean of the data will be correct
-regardless of the range.
-
-### How many buckets should I use in my histogram?
-
-You should allocate as many buckets as necessary to perform proper analysis
-on the collected data. Note, however, that the memory allocated in metricsd
-for each histogram is proportional to the number of buckets. Therefore, it is
-strongly recommended to keep this number low (e.g., 50 is normal, while 100
-is probably high).
-
-### When should I use an enumeration (linear) histogram vs. a regular (exponential) histogram?
-
-Enumeration histograms should really be used only for sampling enumerated
-events and, in some cases, percentages. Normally, you should use a regular
-histogram with exponential bucket layout that provides higher resolution at
-the low end of the range and lower resolution at the high end. Regular
-histograms are generally used for collecting performance data (e.g., timing,
-memory usage, power) as well as aggregated event counts.
-
-### How can I test that my histogram was reported correctly?
-
-* Make sure no error messages appear in logcat when you log a sample.
-* Run `metrics_client -d` to dump the currently aggregated metrics. Your
-  histogram should appear in the list.
-* Make sure that the aggregated metrics were uploaded to the server successfully
-  (check for an OK message from `metricsd` in logcat).
-* After a day, your histogram should be available on the dashboard.

-This directory contains the protocol buffers used by the standalone metrics
-uploader. Those protobuffers are copied from the chromium protobuffers from
-https://chromium.googlesource.com/chromium/src/+/master/components/metrics/proto/
-at 3bfe5f2b4c03d2cac718d137ed14cd2c6354bfed.
-
-Any change to this protobuf must first be made to the backend's protobuf and be
-compatible with the chromium protobuffers.
-
-
-Q: Why fork the chromium protobuffers ?
-A: The standalone metrics uploader needs chromium os fields that are not defined
-by the chromium protobufs. Instead of pushing chromium os specific changes to
-chromium, we can add them only to chromium os (and to the backend of course).
-
-
-Q: What's the difference between those protobuffers and chromium's protobuffers?
-A: When the protobuffers were copied, some chromium specific protobuffers were
-not imported:
-* omnibox related protobuffers.
-* performance profiling protobuffers (not used in chromium os).
