System monitoring utility.

Several modules exist to monitor different aspects of the system. A simple Lua file is used to configure the update interval and the presentation, which can be either simple text or curses windows.

• source (gitlab)
• source (github)

Modules include:

• backlight: screen backlight level.
• battery: battery charge and graph.
• date: date/time on one or more time zones.
• fs: file system space utilization.
• load: system load average.
• thermal: ACPI thermal measurement.

Example:
