A new release of the free real time AIX/6000 system monitor program
is available today at 10 June 1998.  The Monitor-program can be used to
display system statistics of various performance values on a full
screen terminal for AIX releases 3.1, 3.2, 4.1, 4.2 and 4.3. The source code
version of monitor program can be get from ftp-server
     ftp://ftp.mesa.nl/pub/monitor/monitor-2.1.5.tar.gz
or via the web from
     http://www.mesa.nl/pub/monitor/monitor-2.1.5.tar.gz.

New in 2.1.5
 - Support for AIX 4.3
 - many bugfixes
 - Support for the AFS remote filesystem (sort of NFS)
 See CHANGES file for details.
New in since 2.1.2
 - Lots of cosmetic fixes.
 - Color support (available with AIX 4).
 - AFS support (if you have it on your systems).
 - Top display can now be sorted on cpu, memory or paging activity.
 - Interactive commands to toggle many options and change sample times.
 - Other bug fixes.
 - NOTE: semantics of several options have changed a bit. See man pages.

System events monitored in version 2 and some features are:
 - Cpu usage
 - SMP - Symmetric multiprocessing cpuinfo for AIX4 machines (-smp option)
 - Load average (from kernel or by using loadavgd program)
 - Virtual and real memory usage (process and file mapping)
 - Paging information
 - Process events
 - Disk I/O (summary and TOP disks 1.12)
 - Filesystem usage statistics (in logging mode 2.0)
 - TTY I/O
 - Network activity
 - Top cpu users 
 - NFS operations (New to 1.11)
 - More detailed disk I/O screen (New to 1.11 with -disk option)
 - More detailed network I/O screen (New to 1.12 with -net option)
 - Toggle between normal/top/net/disk display using t,n,d keys

Output to file from version 2.0 on.
A few sh/awk script are available to generate plots certain metrics. You
need gnuplot to actually build the graphs.

Monitor package includes following utilities in source code:
 + monitor    - the monitoring program itself
 + top        - a shell script to call monitor -top
 + uptime     - a Berkeley like uptime for pre AIX 3.2.4 systems
 + fps	      - fast ps command which can follow one process (fps -c -p PID)
 + loadavgd   - for pre AIX 3.2.4 systems to calculate load average values
 + loadavgLED - program to show load average values on 3 digit LED display
 + libmonitor.a - library for getting performance statistics from AIX kernel

Some of the monitor displays look approximately like following:
