Though I am just starting my career in Linux. I find your article very good and helpful. Thank you very much for this.
I would definite like to have a mentor like you man.
It’s good, thanks.
Thanks for sharing. Good reference for a neophyte like me 🙂
Also add text console based “hegemon” from https://github.com/p-e-w/hegemon
You can add Netdata, a free, open source, light-weight, browser-based, real-time, performance and health monitoring for systems and applications. It’s amazing how many metrics it makes available.
I wrote a mini script, to get and show the System Information in a minimalistic way in one line. Please check this in:
You know ‘ss’ is the next generation of netstat and will (in my understanding) replace netstat.
‘ip’ will replace ifconfig and arp to name a few.
You also missed LibreNMS a fork of Observium, but with a more vibrant community.
Nice but many linux instances are running as containers in clouds. Visibility of hardware and resources can vary or/and create wrong results. Most of these tools are written when 1 linux instance running on hardware with no virtalization. Tools needs to be updated and here information regarding this issiue should be addressed like works in container or not……
