pc memory usage monitor

display of DataView is inaccurate.Workaround (Pending validation):1. Use the built-in Zabbix variable proc.cpu.util[2. Modify the commands in the script, using the following method instead:First, get the PID of the process name, and then combine top to run the following command:Top-b-n 1-p $pid 2>1 | Awk-v pid= $pid ' {if (= = pid) print $9} '3. Modify the commands in the script, using the following method instead:The PID of the process name is obtained first, and then the relevant data is read

Use the top command to dynamically monitor the memory usage of programs that run for a short period of time. Solution: Top-d 0.01-N2000-B | grep lzma -D specifies the interval at which top data is collected. The value is 0.01 seconds. -N indicates the total number of statistics. Set this parameter to 2000 to ensure that the top node does not end the stati

Use the top command to dynamically monitor the memory usage of programs with very short running times Solution: Top-d 0.01-N2000-B | grep lzma -D specifies the interval at which top data is collected. The value is 0.01 seconds. -N indicates the total number of statistics. Set this parameter to 2000 to ensure that the top node does not end the statistics d

Solution:top-d 0.01-n 2000-b|grep Lzma-d Specifies how often the top collects data, which is 0.01 seconds.-n Specifies the total number of times, which is set to 2000, to ensure that top does not end the statistics during the program run.GREP specifies the process characteristics that need to be counted.How to use:1. Enable 2 sessions, one session runs as above command, another session runs the specified program, and the top command outputs the resource usag
