Hi,
I have a system under test, and I use a script that does a ps.
The output, is in the following format, it's basically the timestamp, followed by the rss and vsize.
09:03:57 68404 183656 68312 181944 69860 217360 67536 182564 69072 183172 69032 199276

09:04:57 68708 183292 68816 181880 68588 183608 67868 188080 69788 199328 69520 212672
09:05:27 68708 183292 68204 181880 68540 183608 68176 196092 70012 196936 69860 215868

My question is this...how do I do the same, but for top,
I really want to track the cpu usage of these 6 processes with the same name, and spit them to a file, every 30s, in the same format as above, i.e. timestamp process1CPU process2CPU process3CPU process4CPU process5CPU process6CP
I've tried the following, but it just hangs at the part where it tries to output the results from top, maybe its because it comes out in a column? I need it in row format, so I can easily import to Excel and analyse.
Here's the script
#!/bin/bash
outputFile=topOutput_`uname -n`
echo "Output: " $outputFile
for ((;;)); do
echo "for loop";
# X=`top | grep --line-buffered softms | awk '{print $6}'`;
# echo "X: "$X;
echo "currentTime...";
currentTime=`date | awk '{print $4}'`;
echo "currentTime: "$currentTime;
echo "To file: ";
echo $currentTime $X >> $outputFile;
echo "foo..."
top | grep --line-buffered softms | awk '{print $6}'
echo "foo: " $foo
sleep 30s;
done
What am I doing wrong? is there an alternative way of achieving this goal?
This is what I'm trying to get as output
Time p1cpu% p2cpu% p3cpu% p4cpu% p5cpu% p6cpu%
09:00:00 65 65 65 65 65 65
09:00:30 70 70 70 70 70 70
09:01:00 70 70 70 70 70 70
09:01:30 70 70 70 70 70 70
09:02:00 80 80 80 80 80 80
09:02:30 65 65 65 65 65 65
etc...
