===========================
Intervals
---------
Some modules define their own update intervals (e.g. most modules that query
an online service), such as to not cause a storm of "once every second" queries.
For such modules, the "global" interval defined via the ``interval`` parameter effectively defines the
highest possible "resolution". If you have a global interval of 10s, for example,
any other module can update at 10s, 20s, 30s, etc., but not every 25s. The status
bar will internally always align to the next future time slot.
The update interval can also be changed on a per-module basis, like
this (overriding the default module interval indicated above):
.. code-block:: bash
$ ./bumblebee-status -m cpu memory -p cpu.interval=5s memory.interval=1m

The update interval is the global "refresh" interval of the modules (i.e. how often
the bar will be updated with new data). The default interval is one second. It is
possible to use suffixes such as "m" (for minutes), or "h" for hours (e.g.
``-p interval=5m`` to update once every 5 minutes.
Note that some modules define their own intervals (e.g. most modules that query

All modules can be given “aliases” using ``<module name>:<alias>``, by
which they can be parametrized, for example:
