System Usage Monitoring
The two graphs shown here inform you about your system
load. They are good indicators of how well is your system performing
with its actual usage and can be used to support decisions on 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 the usage of your main RAM memory (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 graph is shown. Clicking on the
at the right of the graph will
show you the daily, weekly, monthly and yearly graphs in a single
page. This can be handy to plan for system usage. Click on Back to
return to the daily graph.
Clicking on the Refresh button will update the
graphs.
