问按进程名称过滤并记录CPU使用情况

EN

#You can run following script as ./cpurecorder.sh pid filename
#It will generate output file with memory usage and cpu utilisation.
#You can log other variable by searching man for ps.

`enter code here`filepath=/home/rtcsadm              # modify as desired
interval=20                         # reports per minute
timelimit=6000                      # how long to run, in seconds

mydate=`date "+%H:%M:%S"`           # the timestamp
freq=$((60/$interval))              # for sleep function

while [ "$SECONDS" -le "$timelimit" ] ; do
  ps -p$1 -opid -opcpu -opmem -ocomm -c | grep $1 | sed "s/^/$mydate /" >> $filepath/$2.txt
  sleep 3
  mydate=`date "+%H:%M:%S"`
