1. X based system status monitor, older version This is the older version of procmeter. You probably want to install the procmeter3 package instead of this one, unless you need features only present in this older version - namely, the ability to log to a file or syslog, and the ability to read data from named pipes. ProcMeter displays constantly updating graphs of system information. Many different graphs are supported, including: Total CPU usage, CPU used by user, niced, or system processes, CPU idle time, load average, number of context switches, number of processes. Amount of swapping, paging, swap in, page in, swap out, page out. Amount of disk accesses, reads, writes, or interrupts. MB of free, used, buffer, or cached memory. Amount of swap space used. Number of packets received or transmitted over local interfaces, ethernet, or slip/ppp. Number of collisions on ethernet, battery life stats. As if all that wasn't enough, procmeter also allows you to write programs that communicate with procmeter and add new graphs to the display. Procmeter can also log statistics to a file, and play it back later. From Debian 3.0r0 APT
