python memory usage

I think many of my friends will find that their mysql occupies a large amount of internal and cpu resources. To solve this problem, most of us will directly reduce the number of mysql accesses and connections and directly generate static or cache files, below I have more ways to solve mysql's high CPU and memory usage. In order to install the mysql environment for testing, after installation, it is found th

"The proc file system is a pseudo file system, which only exists in the memory and does not occupy the external storage space. It provides interfaces for accessing system kernel data in the form of a file system. Users and applications can obtain system information through proc and change certain kernel parameters. " This section describes how to obtain some firewall-related performance parameters from the/proc file system and how to modify the Kernel

On Mac, you can use the graphical tool Activity Monitor to view the CPU and memory usage of the system. So how can I use the command line to view it?For CPU usage, use the top command.You can also use top for memory usage, but the complete command I commonly use is: top-l 1

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
