top-command

问题 Here I am trying to execute ssh commands and print the output. It works fine except the command top . Any lead how to collect the output from top ? import paramiko from paramiko import SSHClient, AutoAddPolicy, RSAKey output_cmd_list = ['ls','top'] ssh = paramiko.SSHClient() ssh.load_system_host_keys() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(hostname_ip, port, username, password) for each_command in output_cmd_list: stdin, stdout, stderr = ssh.exec_command(each

问题 In Unix/Linux the top command has the -H option to give a more details information about the threads within a process. On Macosx there seems to be no -H option! Is there anything similar for Macosx? 回答1: I think there's no such or similar option in top for OS X, but you can try htop which displays threads in somewhat similar way to htop -H. Although OS X doesn't have htop binary, you can build and install it from source (e. g. according to this guide: https://web.archive.org/web

问题 I was trying to execute this command echo exec("top"); and echo exec("/usr/bin/top"); neither works (returns blank output) does anybody know why? 回答1: Because top is an interactive program that is meant to be run on a terminal, not be executed from a script. You are probably want to run the 'ps' command with arguments which will sort output by cpu utilization. http://www.devdaily.com/linux/unix-linux-process-memory-sort-ps-command-cpu 回答2: It probably works, but exec() doesn't return anything

问题 When running top -b -n 1, the command always returns the same CPU values. Consider the following test run 5 times in succession: [user@server ~]$ top -b -n 5 -d.2 | grep "Cpu(s)" Cpu(s): 18.5%us, 10.0%sy, 0.0%ni, 67.0%id, 4.2%wa, 0.0%hi, 0.2%si, 0.1%st Cpu(s): 39.8%us, 27.7%sy, 0.0%ni, 31.3%id, 0.0%wa, 0.0%hi, 1.2%si, 0.0%st Cpu(s): 39.0%us, 35.4%sy, 0.0%ni, 23.2%id, 0.0%wa, 0.0%hi, 1.2%si, 1.2%st Cpu(s): 41.2%us, 34.1%sy, 0.0%ni, 15.3%id, 1.2%wa, 0.0%hi, 2.4%si, 5.9%st Cpu(s): 59.0%us, 30.1

问题 I am trying to get first 5 lines of top command through shell script & I need to write the output to a csv file ( I need to monitor the result in every 15 seconds ). Finally I need to plot a graph using the obtained datasheet. I got the shell scrip to write the first 5 lines of top command to a txt file : #!/bin/bash echo "execution started.." top -b -n 3 | sed -n '7,1p' >> out.txt while [ true ]; do sleep 15 echo "running.." top -b -n 3 | sed -n '8, 12p' >> out.txt done Here is the out.txt

问题 I would like to join and process the two lines coming out of the top command: shell> top -p 1 -b -d 1 | egrep '^top|^Cpu' top - 15:17:45 up 736 days, 4:32, 3 users, load average: 0.06, 0.03, 0.00 Cpu(s): 0.7% us, 0.8% sy, 0.0% ni, 97.1% id, 1.3% wa, 0.0% hi, 0.0% si When trying to use awk and sed commands, I run into trouble - no output is produced. What commands would I use to get the output to look like this: Time: 15:17:45 Cpu(s): 0.7% us, 0.8% sy, 0.0% ni, 97.1% id, 1.3% wa, 0.0% hi, 0.0%
