atop – For Linux server performance analysis

We’re all familiar with top, a real-time system monitor. Some prefer htop and previously I mentioned iotop for use with storage read/write monitoring.

Linux Performance: Almost Always Add Swap. Part 2: ZRAM

Previously, we looked at how swap space, particularly swapping, can severely slow down Linux performance. We then tweaked Linux kernel parameters to make better use of server memory and to avoid heavy swapping. That article created some debate and good arguments for and against swap space. For example, if you have more than enough memory […]

50 Top Server & Application Performance Monitoring (APM) Solutions

Back in 2014, I compiled a list of top server and application performance monitoring solutions. Sharing that list publicly was a great way to gain feedback and recommendations on other tools available. In time that list grew from 20 to over 100 server monitoring and APM solutions!
