Looking for application monitoring and observability solutions? On this page, I’ve listed the top application performance monitoring (APM), infrastructure monitoring, and observability solutions to date.
Running Linux servers on under 1 GB of RAM (think 512 MB or even 256 MB) can be challenging, but it’s absolutely feasible with the right distro choice.
This list of Linux benchmark scripts and tools should prove helpful for quick performance checks of CPU, storage, memory, and network on Linux servers and VPS.
The top command (referred to below as Linux top) is a command on Unix and Unix-like systems such as Linux, which provides a dynamic real-time overview of a running system.
In the previous article, we looked at how swap space, particularly swapping, can severely slow down Linux performance.
We know that using Linux swap space instead of RAM (memory) can severely slow down performance.
Rule of thumb / TL;DR:
If your system only uses swap occasionally and keeping swap demand within ~20–30% of your physical RAM as zram is enough, ZRAM is the simpler and more effective option.
Many Internet Service Providers (ISPs) like AT&T, Comcast, Xfinity, Cox, Verizon, Spectrum, T-Mobile, and others supply a basic modem/router combo (gateway) to customers.
