script to monitor cpu and memory usage in linux

This value is of type float, but cutting off the decimal part will not be a problem.Īnd last, comparing the obtained value with a constant, we determine the need for restarting the process. Using the formatted '-o pmem=' output, you can get memory consumption in percentage terms. The 'ps' utility is well suited for this, which can take a command name with the option '-C' or the process id with '-p' option. The script will show you the process ID, the owner of the process, the name of the process and how long the processes are running. Second, getting value of consumption process memory. Two scripts are included in this tutorial, which helps you to identify how long the high CPU/memory consumption processes are running on Linux. For this, I think 'crontab' will work well. If you are ready to make an effort, it is useful to start by breaking the task down into stages.įirst, launching the scheduled task. The script is quite ordinary and writing will take much less time than finding a ready-made solution. In addition,Ĭreation is much more interesting and useful.

Therefore, if you have a desire to try to write such a script yourself, then everyone here will readily help you.

For this, we will use the python os module since it provides methods to access both the number of. It's customary to help on this resource, that is, you solve a problem and you don't succeed or you're stuck on something and don't know how to continue. First, we will check the number of both physical and logical CPUs and then check the System Load.
