The server’s been feeling pokey lately, so I wanted to dig around to see if anything was acting up (or if it was just gremlins in the machine). Did some reporting using sar and got this:
sar -r gets the memory dump. sar -u gets the CPU usage dump.
sar -r > memory.txt;
sar -u > cpu.txt
then, grab the text files, clean them up a bit, bring them into Excel, select the columns, and insert chart. Yeah. The whole Excel thing is probably a non-traditional-linux-admin tool. Whatever. Pretty pictures.
CPU is consistently idle. Memory is consistently not pegged. I think we’re doing ok.
