Droid::Monitor

Monitoring Android cpu or memory usage and create their simple graph with Google API.

Gem Version

Read also: https://developer.android.com/training/testing/performance

Installation

Add this line to your application's Gemfile:

gem 'droid-monitor'

And then execute:

$ bundle

Or install it yourself as:

$ gem install droid-monitor

Quick Start with Sample

See under sample file in this repository. The sample use clockwork to run ruby script in particular terms.

$ cd sample
$ bundle install
$ bundle exec clockwork example_cpu.rb

Usage

Followings are only storing data. They don't include cron like clockwork.

CPU

with cpuinfo

require "droid/monitor/cpu"

# initialize
@cpu = Droid::Monitor::Cpu.new( { package: "com.android.chrome" } )

# save data into @cpu.cpu_usage
@cpu.store_dumped_cpu_usage

# export data into filename as google api format
filename = "sample_data.txt"
@cpu.save_cpu_usage_as_google_api(filename)

# export data into filename which is used the above command.
output_file_path = "sample.html"
graph_opts = { title: "Example", header1: "this graph is just sample"}
@cpu.create_graph(filename, graph_opts, output_file_path)

#clear @cpu.cpu_usage
@cpu.clear_cpu_usage

with top command

require "droid/monitor/cpu"

# initialize
@cpu = Droid::Monitor::Cpu.new( { package: "com.android.chrome" } )

# save data into @cpu.cpu_usage
@cpu.store_dumped_cpu_usage_with_top

# export data into filename as google api format
filename = "sample_data.txt"
@cpu.save_cpu_usage_as_google_api_with_top(filename)

# export data into filename which is used the above command.
output_file_path = "sample.html"
graph_opts = { title: "Example", header1: "this graph is just sample"}
@cpu.create_graph(filename, graph_opts, output_file_path)

#clear @cpu.cpu_usage
@cpu.clear_cpu_usage

Graph

Memory

require "droid/monitor/memory"

# initialize
# You can specify target devices with providing device serial which is provided via adb devices.
@memory = Droid::Monitor::Memory.new( { package: "com.android.chrome", device_serial: "device_serials"} )

# save data into @memory.memory_usage
@memory.store_dumped_memory_details_usage

# export data into filename as google api format
filename = "sample_data.txt"
@memory.save_memory_details_as_google_api(filename)

# export data into filename which is used the above command.
output_file_path = "sample.html"
graph_opts = { title: "Example", header1: "this graph is just sample"}
@memory.create_graph(filename, graph_opts, output_file_path)

#clear @memory.memory_detail_usage
@memory.clear_memory_usage

Graph

Net

Android 5.x can't get netstats.

require "droid/monitor/net"

# initialize
@net = Droid::Monitor::Net.new( { package: "com.android.chrome" } )

@data_file = "sample.txt"
@data_file2 = "sample2.txt"

# save data into @net.tcp_rec, @net.tcp_snd
@net.store_dumped_tcp_rec
@net.store_dumped_tcp_snd

# export data into filename as google api format
finename1 = "sample_data1.txt"
finename2 = "sample_data2.txt"
@net.save_cpu_usage_as_google_api_rec(finename1)
@net.save_cpu_usage_as_google_api_snd(finename2)

# export data into filename which is used the above command.
output_file_path1 = "sample1.html"
output_file_path2 = "sample2.html"
graph_opts = { title: "Example", header1: "this graph is just sample"}
@net.create_graph(@data_file, graph_opts, output_file_path1)
@net.create_graph(@data_file2, graph_opts, output_file_path2)

# clear @net.tcp_rec and @net.tcp_snd
@net.clear_tcps
or
@net.clear_tcps_rec
@net.clear_tcps_snd

Graph

  • receive tcp

  • send tcp

Gfxinfo

require "droid/monitor/gxfinfo"

# initialize
@gfx = Droid::Monitor::Gfxinfo.new( { package: "com.android.chrome" } )

# save data into @gfx.gfxinfo_usage
@gfx.store_dumped_gfxinfo_usage

# export data into filename as google api format
data_file_gfx = "sample_gfx.txt"
data_file_mem = "sample_mem.txt"
data_file_frame = "sample_frame.txt" # Can't get frame rendered if api level of target devices are 21 or 22.(Android 5.x)
@gfx.save_gfxinfo_usage_as_google_api(data_file_gfx, data_file_mem, data_file_frame)

# export data into filename which is used the above command.
output_file_path1 = "sample1.html"
output_file_path2 = "sample2.html"
output_file_path3 = "sample3.html"

graph_opts = { title: "Example", header1: "this graph is just sample"}
@gfx.create_graph(@data_file_gfx, graph_opts, output_file_path1)
@gfx.create_graph(@data_file_mem, graph_opts, output_file_path3)
@gfx.create_graph(@data_file_frame, graph_opts, output_file_path3)

# clear @net.tcp_rec and @net.tcp_snd
@gfx.clear_gfxinfo_usage

Graph

  • gfx

  • memory

  • frame

Can't get frame rendered if api level of target devices are 21 or 22.(Android 5.x)
