New page

Today I needed to sort ps by the total CPU time. I also wanted to sum all the same type processes together. Here's the script I came up with

<geshi lang="ruby">
#!/bin/env ruby
#
# Given the output from 'ps -o user,time,nlwp,fname' this script will sum the CPU time
#

header = nil
procs = {}
procs.default = 0
while((line = STDIN.gets))
f = line.chomp.split(' ')
if !header then
header = f
TIME = f.rindex('TIME')
CMD = f.rindex('CMD') || f.rindex('COMMAND')
else
time = f[TIME].split(':')
seconds = time[0].to_i * 60 + time[1].to_i
cmd = f[CMD]
procs[cmd] += seconds
end
end

sum = 0.0
procs.each { |k,v| sum += v }
sorted = procs.sort { |a,b| b[1]<=>a[1] }
sorted.each do |k|
puts sprintf("%-10s %5.2f%%", k[0], (k[1] / sum) * 100.0)
end
</geshi>

Here's a sample of it's usage:
<geshi lang="bash">
$ ps -A -o user,time,nlwp,fname | ./sumcputime.rb | head
java 27.19%
dataserv 20.10%
Xvnc 7.21%
view_ser 4.06%
backupse 3.86%
httpd 3.64%
nscd 2.81%
omniName 2.38%
se.sparc 2.34%
compute_ 2.10%
</geshi>
