Sweet Little Monitoring Tool – dstat
I was talking to a few folks today and mentioned that I wanted to be able to snapshot the CPU usage on my ticker plant box every few seconds during the day so I could make some intelligent sizing decisions as to what can live on one box, and they mentioned dstat.
This is one sweet little monitoring tool.
I've set up an alias to run the following:
dstat -t -c -m -n --output dstat_data.csv 5
and on the console I'll get the lovely color output, but to the file dstat_data.csv I'll get a nice importable data set. Sweet!
This is why I love building and running code on linux - it's just so darn neat!
