How to Check the Health of a Unix/Linux Server

Filed under
HowTos

An occasional health checkup will improve a computer system's service and extend its useful life.

There are six steps to a basic health checkup for a Unix/Linux server but before starting the checkup run the vmstat system utility program.

vmstat is a Unix/Linux command that displays the status of the virtual memory kernel plus some other useful system statistics. It can be run by typing 'vmstat 5' which will display one line of data every 5 seconds until it is canceled.

I recommend that you run vmstat for a 24 hour period and save the information into a file. This can be done by typing 'vmstat 1200 > /tmp/vmstat.data.'

After the 24 hours has elapsed cancel the command. The file /tmp/vmstat.data will contain three lines of output for each of the 24 hours.

Why Dell’s gamble on Linux laptops has paid off

The whole juggernaut that is now Linux on Dell started as the brainchild of two core individuals, Barton George (Senior Principal Engineer) and Jared Dominguez (OS Architect and Linux Engineer). It was their vision that began it all back in 2012. It was long hours, uncertain futures and sheer belief that people really did want Linux laptops that sustained them. Here is the untold story of how Dell gained the top spot in preinstalled Linux on laptops. Where do you start when no one has ever really even touched such a concept? The duo did have some experience of the area before. George explained that the XPS and M3800 Linux developer’s laptops weren’t Dell’s first foray into Linux laptops. Those with long memories may remember Dell testing the waters for a brief while by having a Linux offering alongside Windows laptops. By their own admission it didn’t work out. “We misread the market,” commented George. Read more Also: New Entroware Aether Laptop for Linux Powered with Ubuntu

A Short MATE Desktop 1.17 Review in February 2017

MATE 1.17 is a testing release, it has no official announcement like 1.16 stable release (odd = unstable, even = stable). But what made me interested is because Ubuntu MATE 17.04 includes it by default so I write this short review. The most fundamental news is about MATE Desktop is now completely ported to GTK+3 leaving behind GTK+2. You may be interested seeing few changes and I have tried Ubuntu MATE 17.04 Alpha 2 to review MATE 1.17 below. Enjoy MATE 1.17! Read more Also: What's up with the hate towards Freedesktop?
