System info in solaris and linux

If you work for a non microsoft shop, its highly likely that you would develop and/or deploy your applications in linux or solaris systems. Our windows to the target system is the ubiquitous command line via ssh. Here are some of the commands that I find useful to get the details of target system.

Solaris commands

Hardware deatails

Processor /usr/sbin/psrinfo -v

Memory /usr/sbin/prtconf -v | grep Memory

HD /usr/sbin/format < /dev/null

Current statistics

memory statistics /usr/bin/vmstat

io statistics /usr/bin/iostat

network statistics /usr/bin/netstat

disk space usage /usr/sbin/df

Process details

list of processes running /usr/bin/ps -aef

memory usage for a given process /usr/bin/pmap processid | grep total

list of ports open for a given process

/usr/proc/bin/pfiles processId | grep "port: portId"

I have listed only the commands. A simple google or map page should give you details about each of the command. I will follow it up with Linux command later.
