Dstat CPU usage for one specific process

linux cpu cpu-usage measure

No, this is not possible with dstat currently.

I always envisioned to make this possible, but never got around to doing it.

You can use command | grep specific_text

for example test dstat | grep puppet

to saving output result in a log file you have two options :

using --output filedstat --time --cpu --top-cputime --output /tmp/dstat.log | grep puppet

using command > filedstat --time --cpu --top-cputime > /tmp/dstat.log | grep puppet

for appendind logs :dstat --time --cpu --top-cputime >> /tmp/dstat.log | grep puppet

here is screenshots of both commands

According to your comments may these commands helps you :

(1) save stats in a file dstat --time --cpu --top-cputime --output my.log

(2) apply filtering to log file and save results to file cat my.log | grep httpd > myhttpd.log

(3) final results cat myhttpd.log

see the screenshot of results here
