Sample client for istatd

IPhone owners can use a great app for servers monitoring - istat. On the server you must install the istatd daemon. More information can be read here: http://blogs.sun.com/karim/entry/monitoring_opensolaris_from_an_itouch.
Here an example of a console client for istatd, you can use this data for plotting, etc:
$ gcc -o istatd_client istatd_client.c -lsocket -lnsl
$ ./istatd_client
Usage: istatd_client <server_ip> <server_port> <server_code>
Example output from OpenSolaris server:

/istatd_client XX.XXX.XX.X 5109 12345
Connected to XX.XXX.XX.X on port 5109

...

Looking through istatd code, you can easily recognize what's mean all these variables (for example "u" in <CPU> denotes cpu_user usage).

Using ddu scripts

Have you ever looked in the "/usr/ddu" directory? Console-lovers can use some of these scripts and get the almost same output as from the "ddu" graphic utility. For example, I changed the probe.sh script a bit and now I can get ddu-like info from console:
