uuid plugin: Add a plugin which sets the hostname to an UUID.
Florian Forster wrote:
> Just out of curiosity: Why don't hostnames work for you?
For guests there's the question of what we put in the hostname field. The
previous plugin (libvirtstats) puts the guest's name in this field, but there
are some problems with this:
physicalserver1 <--- (hostname of physical server)
|
\--- database <--- (name of guest)
\--- web
physicalserver2
|
\--- database
\--- web
coldbackupserver
|
(no guests)
Guest names aren't really unique. Different physical servers may have guests
with overlapping names as in the example above. Also guest names aren't fixed.
Xen in particular renames guests at will. For example if a guest is about to
migrate then Xen renames the guest as 'migrating-foo' and if the guest is about
to shutdown Xen renames it as 'Zombie-foo'. The administrator of the physical
server can also rename guests.
While you're migrating you'll have an intermediate situation like this:
physicalserver1
|
\--- migrating-database
\--- migrating-web |
| migration
coldbackupserver |
| V
\--- database
\--- web
During live migrations the old instance ('migrating-foo') is still running.
The UUID is unique across physical servers, and is copied by migration and
preserved across shutdowns so if you care about which guest your stats "really"
came from then only the UUID tells you this.
Guests also have a hostname which is separate from the guest's name (the
guest's name is stored in the hypervisor, the hostname is stored inside the
guest's kernel). However it's not feasible to access the guest's hostname from
the hypervisor since this would involve some sort of snooping into the guest
kernel. The guest might be running Windows or FreeBSD etc. The only feasible
way to get this is to run an instance of collectd inside each guest, but then
the uuid plugin will also work in this scenario and can get the UUID since it
is exposed inside the guest either through an emulated BIOS or in
/sys/hypervisor/uuid.

src/utils_cache.[ch]: Added a global cache for all values that are dispatched.
The cache translates counter values to gauge values using the last counter
value available. This can then be used to check against threshold values, as
we'll need to do for monitoring functionality.
Right now the cache doesn't do much: It sits there and caches the values, but
is not yet ever queried. The already implemented (but so far unused) function
`uc_get_rate' returns an array of gauge_t values.
The longterm goal is to have the network, rrdtool and unixsock plugins use this
cache, too. This will require some `plugin specific' data with appropriate
control structures and, which is likely the hardest part, some clever locking
for all that.

perl plugin: Set $0 to "collectd".
perl_parse() has to set it to "-e" which is not very meaningful. It would
be even nicer to set it to argv[0] but this is not available from inside
the plugin.

plugin.h: Make DEBUG() a noop when compiling without debugging support.
This saves a couple of useless calls to plugin_log() which the compiler
does not detect and remove itself.
A couple of DEBUG()'s in the apcups, hddtemp, mbmon and ntpd plugins have
been upgraded to INFO()'s. All of them provide error messages of failed
system / libc calls which should be available to the user somehow.
Besides, they use a local string buffer which generates an "unused
variable" warning if DEBUG() expands to a noop.

During the creation of a rpm on Mandriva 2007.1 from tar.bz2 sources, and by
