+
- match_regex
Match values by their identifier based on regular expressions.
- target_replace
Replace parts of an identifier using regular expressions.
+ - target_scale
+ Scale (multiply) values by an arbitrary value.
+
- target_set
Set (overwrite) entire parts of an identifier.
network plugins, makes sure your resources are used efficiently. Also,
since collectd is programmed multithreaded it benefits from hyperthreading
and multicore processors and makes sure that the daemon isn't idle if only

* Once set up, hardly any maintenance is necessary. Setup is kept as easy
as possible and the default values should be okay for most users.
