System Usage Monitoring
This section's two graphics inform you about your
system's load. They are good indicators of how well your system is
performing with its actual usage, and can be used to support decisions
regarding CPU/RAM upgrades.
- avgload: represents the CPU average usage for the last 24
hours. The unit used roughly indicates the number of processes trying
to access the CPU at the same time. A normal load should remain below
2. If the load is between 2 and 5, your system is a rather busy one.
Above 6, you should consider upgrading your CPU.
- memusage: represents your main RAM memory's usage (in
megabytes). Different colors are used to give more precise information
about the way memory is used (RAM used in black, RAM free in green,
Swap in red, and cache in yellow).
By default, a daily graphic is shown. Clicking on
at the right of the graphic
will show you the daily, weekly, monthly and yearly graphics in a
single page. This can be handy to plan for system usage. Click on Back
to return to the daily graphic.
Clicking on the Refresh button will update the
graphs.
