Sysstat includes a component that collects the measured values in the background.

(See the box titled "Installing Ganglia.") If you do not need graphical analysis, install the sysstat package instead of Ganglia.
On Raspbian, you only need to set up Ganglia packages the configuration work is minimal. Although Ganglia is suitable for performance monitoring in clusters, it can also handle single computers. Ganglia is a useful monitoring tool for working with the Raspberry Pi. This record saves you from having to keep an eye on the window with the top output during your tests. Sophisticated monitoring programs, however, regularly record the status of various readings and can thus provide historical data. Top provides important evidence, but only for the current status. CPU load usually isn't a problem, but if you are consistently seeing high values for the %CPU, you actually need a faster CPU.įigure 2: … if you have a high value for "wait," a more powerful CPU would just wait faster for data. A summary at the top displays the overall system load.Īs you can see in Figure 1, the overall %CPU usage is up to 98.1. The top command displays the processes running on the system and the amount of system resources each process is consuming. When beset by performance problems, experienced Linux users will turn to the top utility, which outputs information about the current system load. With performance problems of this kind, regardless of the hardware platform, the best strategy is always: measure, change, and measure again. I knew I needed to find some performance tweaks somewhere. I was able to complete the ownCloud installation, but the response times were intolerable. Recently, I tried to set up my Pi with the private cloud app ownCloud, and the sluggish performance prompted me to investigate the options for performance tuning on the Raspberry Pi. Raspberry Pi is perfectly suited for hosting your own web projects, but more complex applications can make the tiny Pi break a sweat.
