System Monitor (sysmon.sh) is the bash script which shows the real-time usage of CPUs, NICs, RAM (conventional memory, HugePages, and swap). The main distinction of this script from many other utilities is that it also shows HugePages utilization. Read the HugePages Configurator post for more information.

HugePages Configurator

By |2019-01-20T19:18:18+00:00August 27th, 2017|Linux, Scripts|0 Comments

HugePages Configurator (hugecfg.sh) is the bash script which allows you to easily configure HugePages and show real-time values as well as settings in a config file. HugePages is a feature integrated into the Linux kernel 2.6. Enabling HugePages makes it possible for the operating system to support memory pages greater than the default (usually 4KB). Using very large page sizes can improve system performance by reducing the amount of system resources required to access page table entries. HugePages is useful for both 32-bit and 64-bit configurations. HugePage sizes vary from 2MB to 256MB, depending on the kernel version and the hardware architecture.
