all pullers have a default 1s cool down before next pull.
We can adjust these later.
Also add puller stats in StatsdStats
Test: unit test
Change-Id: I71894a24c41e059d841591312dbb852f54387b7d
Splits out DurationAnomalyTracker-specific functions into their own
subclass.
Test: the unit tests and CTS tests
Change-Id: Id6eb74d232b4a9c3a932d805d1ba3f0ba43a88b1
+ Add a real HashableDimensionKey as a wrapper of the dimension.
So we can get rid of the maps that we kept.
Pay down technical debt and reduce memory usage.
Test: statsd_test & manual
Change-Id: I233280cf1e2ce93da6a8cd4e8514abb066f4016d
bug fix: GaugeMetricProducer now works better with pulled events.
unit test also includes GaugeMetricProducer_test

Since there is a separate guardrail for memory used by uid map, we
no longer add the memory from uid map with the memory per each
config's metrics. We also prevent the byte size check from happening
too frequently. In order to mock the MetricsManager, we refactor
some of the existing methods.
Test: Added unit-tests and verified they all pass on marlin.
Change-Id: I15cf105f7d95f4016fdb0443b0a33eebe862cafb
+ StatsdStats is the global class that tracks the stats about statsd.
+ Added guardrail for classes that have a map which could potentially grow
unboundedly with the number of logs.
TODO: add unit tests & CTS for StatsdStats, and guardrail
add stats for pulled atoms.
Test: statsd_test
Change-Id: I0ea562de4dd3f6162f7923a9c193420b482c1d51
1. Create intent receiver in StatsCompanionService to listen to shutdown
events.
2. Create StatsWriter class to handle disk writes and deleting files.
3. Update StatsLogProcessor, ConfigManager, and StatsService to handle
files on disk using StatsWriter.
4. Add a wrapper for ConfigMetricsReport.
Still TODO is to be able to add a guardrail to prevent accumulating
excessive amount files on disk, which will be followed up by another
change.

Change-Id: Ia0b3af315af545daa8b0078b3700c600aa7c285f
Features:
+ Push baseline config to statsd
+ Have buttons to write events to StatsLog (plug/unplug, screen on/off, wake locks)
+ Dump stats log report, and display it on screen (currently support DurationMetricData display).
Test: manual
Change-Id: Ia58d215d30ed7570c0aa1b0627d3b88f8355d425
2/ Init anomaly from config based on the public language.
3/ Unit tests for anomaly detection in count/gauge producer.
4/ Revisit the duration tracker logic.
Test: unit test passed.

Added a malloc debug cmd to find memory leak and where
the most heap allocations are with backtrace.
More info: malloc_debug/README.md
The util class is borrowed from audio server.
Usage:
adb shell stop
adb shell setprop libc.debug.malloc.program statsd
adb shell setprop libc.debug.malloc.options backtrace
adb shell start
adb shell cmd stats meminfo
Also,
adb shell dumpsys meminfo [statsd_pid]
also gives you the overall summary of the memory usage.
Test: manual

Also make atom WakelockStateChanged use the "Type" enum instead of int32.
Test: Unittests are passing. Statsd is working.
Change-Id: I0909e2d97297f78996a81366d66aae62d5bf5ce1
StatsPullerManager is refactored so that we can mock it.
It may need more refactor pass to make is safer for longer runs.
Test: unit test

Note: these pullers return monotonically increasing numbers.
The uids could include isolated uids that needs further translation in
statsd.
Test: manually tested on device and check print outs
Change-Id: I7097aec0417a3ac567b9b86149b757ac27cd58d8
+ Support nested counting
+ Support StopAll
+ Added default_condition to SimpleCondition config
+ Some refactoring/clean up
+ Added unit tests
Test: Added unit tests, statsd_test
Change-Id: I6564ac2e068ce6810e8090c0818064c625c7847a
Re-added CountAnomalyTracker (under the name DiscreteAnomalyDetector).
It is now able to handle dimensions.
Test: unit test passed.
Change-Id: I133fcf6db99b9e305756f7ee5891c25f0f276348
And other miscellaneous fixes.
+ clang-format
+ 2 bug fixes, one in dump-report command, one in ResourcePowerManagerPuller

Note:
This is for value metric. The default operations is sum the diffs.
The test uses kernel wake lock, which also needs dimension by kernel
wake lock name.
The test is a bit cumbersome as it needs StatsCompanionService to do
the alarm, which is not exact alarm.
The internal state of a slice of bucket would look something like this:
4:ipc0000005e_727_android.hardwar
0 0
4:SensorService_wakelock
40 64
4:ipc0000005c_727_android.hardwar
...
Test: manual test on device.
Change-Id: I2ed0ac7d3c5fcba8b7611d46f38a38ffd8bdc92a
Newly supported metrics examples:
1) Compute [Total|Max] duration of [an app] holding [ANY] wake lock while [this app] is in
[background] and [screen off], bucket size 30seconds, and slice output by uid.
2) Compute [Total|Max] duration of [ANY app] holding [ANY] wake lock while [this app] is in
[background] and [screen off], bucket size 30 seconds.
+ DurationMetric proto has a "what" which is a SimpleCondition. It defines the atom level start
and stop of the duration timer, and it has its atom dimension. e.g., for wake locks, the atom
dimensions wil be uid and wl name.
+ Now dimension is explicitly specified in SimpleCondition proto instead of inferred from the "link"
+ Added support for "Or" and "Max" through 2 layers of aggregation.
TODO: (1) The way we track slicedCondition in duration metric is not efficient. optimize!
(2) The output dimension should all use int32 instead of KeyMatcher. Fix in a future cl.
Test: Added some unit tests using gmock. Will add more unit tests.
Change-Id: I58a827624f01f9a54fcb80709c4de4ff94a8bc67
We send a snapshot of all installed apps with their uids every time
a user is added or removed and when statsd is started.
We keep track of the latest timestamp when a config key has retrieved
the UID map data. This allows us to remove older data when we're
guaranteed that all config sources have retrieved the old data.
Test: Added more unit tests to UidMap_test and passed on marlin-eng.
Change-Id: I34a3d61e75eedec44b98d896d7f6db0bc383f46a
statsd entries to clients. This change only includes changes on statds
side and does not include java library for clients to import. Java
library will be a separate change as it requires system api review.
Test: statsd, statsd_test
Change-Id: I306c6e9687801668cc0145b12d38406bfe634775
+ Started to use ProtoOutputStream in EventMetricProducer.
[TODO]: We need to auto-generate fieldIds for StatsLogReport, XXXMetricData, etc.
[TODO]: We need to add Enum type to liblog, otherwise we cannot reconstruct a proto containing
an enum
+ Some refactor in metric initialization code. There are still boiler plate code, because Metrics
are similar but with subtle differences.
Test: statsd_test
Change-Id: Id7e3212566249a8139b9680f04238c455d50c1b8
Previously, pulled data was returned as a string. We instead
return the data as an array of StatsLogEventWrapper, which encodes
using the binary-encoded format liblog uses. StatsD uses the same
parsing as for pushed events to convert these. This CL also fixes
the parsing of log_msg since the strings were previously emptied
before we had a chance to read the values.
Note that the cpp-aidl can't support List of Parcelable, so we
have to return the results as an array.
Test: Manual using the new command in StatsService to print results.
Also created a new unit-test by creating a dummy pull code of -1,
but this test is deleted since it required creating a fake output in
StatsCompanionService.
Change-Id: I1cfb9ea081a59292a60e934e8527adc40982ed80
Now we support following metrics:
<Duration> of [app holding a wake lock], while [*this app*] is [in background] [AND] [screen is off]
[Slice] the output by [app name, wake lock name], with bucket size [30sec]
+ Also added onDumpReport() api in MetricsManager, it can be called from client to fetch the data from
statsd
+ Also added command line tool to dump the StatsLogReport from all metrics for debugging.
+ Synced proto from google3. with a pending cl (cr/172359050)
TODO: We need to add tons of tests to test the Metrics. I will work on it after this CL so people
can be unblocked.
I locally test the duration metric with wake lock with an app that generates StatsLog events.
Test: statsd_test
and manual test, and run:
adb shell cmd stats dump-report
We have a default config, which contains a metrics to count PROCESS_START event sliced by
package name.
Change-Id: I4838cc6cf025c143b7e84f43040703a78121fd25
It stores all of the parsed fields in a single vector, and
provides accessor methods to get at fields by index with
their correct type.
Test: statsd_test
Change-Id: I4fa94e4ce52db3ac87f19b62f9c85398de6e8145
- Add a ConfigManager class that tracks the configurations
that have been passed to us. Configurations are now
tracked by tuples of (uid,tag), where the tag is an
app-defined string, in case a single uid has multiple
configurations.
- Move all of the initialization into StatsService.
- Get rid of the ability to have multiple LogListeners. Raw
events are now pushed directly into StatsService, which
can distribute them to the interested parties (and will
eventually be able to do the proper locking).
- Add Log.h, which sets our LOG_TAG correctly.
- Move some of the related files that I expect will grow some
into their own subdirectories.
