This is a rewrite of commonly used munin plugins in C as a single binary.
|
|
|
|
|
The purpose is reducing resource usage:
|
2008-06-21 13:52:41 +02:00
|
|
|
* disk space: the binary is smaler than the plugins together
|
|
|
|
|
* more diskspace: it has no dependencies on other programs
|
|
|
|
|
* less forks: it does not fork internally
|
|
|
|
|
* faster startup: it doesn't start perl or shell
|
|
|
|
|
* less memory: just a small C program
|
|
|
|
|
* less file accesses: one binary for many plugins
|
|
|
|
|
This can be useful for machines with restricted resources like embedded
|
|
|
|
|
machines.

Disadvantages?
|
|
|
|
|
~~~~~~~~~~~~~~
|
|
|
|
|
You lose flexibility. You can no longer just edit the plugin and if you try
|
|
|
|
|
you have to be very careful not to break it. If you want to deploy this you
|
|
|
|
|
have to create one binary for each architecture.

How to use?
|
|
|
|
|
~~~~~~~~~~~
|
|
|
|
|
After compiling there will be binary munin-plugins-busybox. You can just
|
|
|
|
|
replace symlinks in /etc/munin/plugins/ with symlinks to this binary.
