Introduction

Process Monitor is an advanced monitoring tool for Windows that showsreal-time file system, Registry and process/thread activity. It combinesthe features of two legacy Sysinternals utilities, Filemon andRegmon, and adds an extensive list of enhancements including rich andnon-destructive filtering, comprehensive event properties such sessionIDs and user names, reliable process information, full thread stackswith integrated symbol support for each operation, simultaneous loggingto a file, and much more. Its uniquely powerful features will makeProcess Monitor a core utility in your system troubleshooting andmalware hunting toolkit.

Overview of Process Monitor Capabilities

Process Monitor includes powerful monitoring and filtering capabilities,including:

  • More data captured for operation input and output parameters
  • Non-destructive filters allow you to set filters without losing data
  • Capture of thread stacks for each operation make it possible in manycases to identify the root cause of an operation
  • Reliable capture of process details, including image path, commandline, user and session ID
  • Configurable and moveable columns for any event property
  • Filters can be set for any data field, including fields notconfigured as columns
  • Advanced logging architecture scales to tens of millions of capturedevents and gigabytes of log data
  • Process tree tool shows relationship of all processes referenced ina trace
  • Native log format preserves all data for loading in a differentProcess Monitor instance
  • Process tooltip for easy viewing of process image information
  • Detail tooltip allows convenient access to formatted data thatdoesn't fit in the column
  • Cancellable search
  • Boot time logging of all operations

The best way to become familiar with Process Monitor's features is toread through the help file and then visit each of its menu items andoptions on a live system.

RegMon - in-Kernel MAC-Layer Monitoring

To perform the monitoring, we leverage the lightweight kernel-to-userspace debug file system (debugfs)This serves two purposes:

  1. it enables a simple file-based configuration of RegMon for its in-kernel operations from the userspace
  2. the actual trace-file from the kernel can be accessed via standard file read (e.g., with tail, cat) from the userspace.

For the actual measurements, it is possible to access Atheros control and status registers stored in the card memory through the PCI bus. Each of the Linux drivers (i.e., Madwifi, ath5k and ath9k) has its own C functions or macros to access the memory-mapped 32-bit register content, as shown at the bottom of the RegMon picture.

RegMon is implemented as a single kernel driver patch for each of the supported three drivers, without the need for additional modules, daemons or user-space applications.All main functions of RegMon and their interactions are:

The trace-file generated by RegMon is currently formatted as space separated list of measurement values, which turned out to be a sufficient format to parse and process the trace file for further analysis.

How to install RegMon (under Linux OpenWrt [https://openwrt.org/])

  1. copy RegMon patches (ath5k and/or ath9k) into openwrt/package/kernel/mac80211/patches/ath
  2. re-build mac80211 subsystem by: make package/mac80211/{clean,compile} or re-build complete OpenWrt
  3. install new mac80211 package or flash full image to your router

How to show RegMon WiFi busy-state plots in your local routers web-interface

  1. point your Linux LEDE feeds.conf to our RegMon repository by adding the following line to your feeds.conf:
  1. trigger a feeds update
  2. select our luci_app_regmon from make menuconfig under menu LUCI
  3. rebuild your LEDE image
  4. flash a new image or install the luci_app_regmon with the help of opkg

How to use RegMon sampling

This first 7 registers are hardcoded into RegMon, which are:

  • register_0 = TSF upper time stamp
  • register_1 = TSF lower time stamp
  • register_2 = MAC clock ticks
  • register_3 = tx_busy state in clock ticks
  • register_4 = rx_busy state in clock ticks
  • register_5 = energy_detection state in clock ticks
  • register_6 = TSF lower time stamp

Specify you own register_7.11 via:

  • set the sampling interval in nanoseconds (e.g. 50000ns = 20kHz sampling rate)
  • read RegMon data e.g. via:

For available Atheros registers take a look at:

  • collect RegMon traces, parse, analyze and plot them(in the script folder there are several unsorted awk, shell, R & python scripts that I wrote & use . ToDo: clean-up)

Example of RegMon's logging output

Parse logging output of RegMon to prepare plotting

In order to plot your register values that were collected by RegMon, someone could parse and precalculate certain values of interest.

The provided awk script parse_default_RegMon-trace.awk is such an example of preprocessing the output of RegMon for proper plotting. It performs the following operations with RegMon default output:

  • calculate the absolute and relative difference of timestamps and register counters for each line sampled
  • account for the baseband MAC clock rate at different IEEE 8021.11 modes, e.g:
  • 802.11g 20MHz channel width @2.4GHz -> MAC clock rate = 44MHz
  • 802.11a 20MHz channel width @5GHz -> MAC clock rate = 40MHz
  • 802.11n 40MHz channel width @2.4GHz -> MAC clock rate = 88MHz
  • 802.11n 40MHz channel width @5GHz -> MAC clock rate = 80MHz
  • all other MAC clocl rates at different channel width are a multiple of those given above
  • change hexadecimal representation into decimal
  • add an optional header to the parsed data

You can use the provided awk parser script for ath5k by issuing:

or for ath9k by using:

this leads to the following output:

where:

  • ktime = kernel time stamp
  • d_tx = absolute tx busy state count difference in ticks from previous sample
  • d_rx = absolute rx busy state count difference in ticks from previous sample
  • d_idle = absolute idle state count difference in ticks from previous sample
  • d_others = absolute (energy_detection - rx_busy) state count difference in ticks from previous sample

.. and now you can plot your mac busy state distribution over time. I prefer Rscript for plotting and so there is an example Rscript plot_MAC-states_from_RegMon.r which generates the output plot RegMon.png. For the Rscript to work you need R and the R packages: gglpot2, reshape2 and scales. Samsung gt-s5253.

Best practice for experimentation with RegMon (but unsecure)

  • RegMon traces at high sampling intervals create quite a bit of measurement data. The use of a compression stage is recommended and I prefer the lzop compressor which compresses a RegMon trace by a factor of ~4 with low cpu impact:
  • if you do not have sufficient local disk space on your router, I use netcat on the router and client, to transfer the RegMon trace e.g. over ethernet:
  • on your router open a netcat server:
  • on your Laptop connect to your router and save the actual trace file:

This RegMon git repo includes:

  • RegMon measurement tool provided as patches for ath5k, ath9k and madwifi Linux drivers in OpenWrt
  • shell scripts to set up measurements on OpenWrt WiFi routers
  • parser scripts (mainly AWK) to bring the raw RegMon data in proper shape to analyse with R
  • R scripts to perform statistics and generate plots
