I find that reading the documentation sometimes helps. [EDIT: In the 'doc' folder, click on AVSMeter.html.]

In brief

Usage: AVSMeter script.avs [switches]
Switches
-avsinfo Display extended Avisynth info
-info [-i] Display clip info
-log [-l] Create log file
-csv Create csv file
-gpu Display GPU/VPU usage (requires GPU-Z)
-range=first,last Set frame range
-timelimit=n Set time limit (seconds)
-priority=n Set process priority (1:low, 2:normal, 3:high)


"-avsinfo"
Displays extended info about the installed Avisynth version and the plugin sub-system. If a custom avisynth.dll is specified in the ini file, info about that file will be displayed. The "-avsinfo" switch can be combined with "-log" in order to write the info to a log file ("avsinfo.log") which is created in the current (working) directory unless the INI option "LogDirectory" points to another (valid) directory. The log file contains additional info about OS/hardware, a list of DLL dependencies for avisynth.dll and all auto-load plugins and a list of internal/external Avisynth functions.

"-log"
Creates a log file with various details about the installed Avisynth version, clip info, runtime results, a copy of the script and a performance data table with the measured details about each frame/frame interval. The log file is created in the same directory as the script unless the INI option "LogDirectory" points to another (valid) directory.
Note: The numbering of the frames in the performance data section is not zero-based, i.e. the first frame is 1, not 0.

"-csv"
Creates a CSV file containing the performance data formatted as comma-separated values for direct import in Excel or a similar spread sheet program (OpenOffice, LibreOffice). The CSV file is created in the same directory as the script unless the INI option "LogDirectory" points to another (valid) directory.
Note: The numbering of the frames in the .csv file is not zero-based, i.e. the first frame is 1, not 0.

"-gpu"
Enables display of the GPU/VPU usage which of course is only useful if a filter that uses the GPU is in the chain. AVSMeter uses GPU-Z to access the graphics card sensors through a shared memory space. GPU-Z has to be running (the window can be minimized to the system tray) before running AVSMeter.

"-range=first,last"
Specify the range of frames to be processed. For example, "-range=1500,1999" processes 500 frames starting at frame 1500. Without "-range" AVSMeter processes all frames of the script.
