The above command will show the current process running on the system with memory they are using. This will become very handy once you are looking for which process is taking memory and how much. This command will sort the memory usage in ascending and descending order. 4.vmstat -s This w...
This is the amount of memory that the database server uses for shared memory buffers. If this value is too low, the database would use more disk, which would cause more slowness, but if it is too high, could generate high memory utilization. According to the documentation, if you have ...
Alternatively, you can pipe the output of the ls command into the grep utility to use the same idea of listing only directories in Linux environments. The syntax of this variation will be as follows: # ls -F | grep "/$" Use GUI File Managers to Find Folder Size in Linux If you have...
Monitoring system resources is crucial for the optimum performance of a server. Memory usage, in particular, is a key indicator of system performance and stability. Linux does not inherently store long-term, detailed system resource utilization data. For instance, tools liketop,htop, andfreeprovide...
