Thorhallur Sverrisson 3ba15c1ddb Adding support for /proc/buddyinfo for linux free memory fragmentation. 
/prod/buddyinfo returns data on the free blocks fragments available
for use from the kernel.  This data is useful when diagnosing
possible memory fragmentation.

Christian Schwarz f29f3873ea Add a collector for ZFS, currently focussed on ARC stats. 
It is tested on FreeBSD 10.2-RELEASE and Linux (ZFS on Linux 0.6.5.4).

On FreeBSD, Solaris, etc. ZFS metrics are exposed through sysctls.
ZFS on Linux exposes the same metrics through procfs `/proc/spl/...`.

In addition to sysctl metrics, 'computed metrics' are exposed by
the collector, which are based on several sysctl values.
There is some conditional logic involved in computing these metrics
which cannot be easily mapped to PromQL.

Not all 92 ARC sysctls are exposed right now but this can be changed
with one additional LOC each.

Dominik Honnef 38c5890428 Reuse devinfo struct 
The devstat API expects us to reuse one devinfo for many invocations of

Dominik Honnef ea55d0f5cb Don't race in FreeBSD devstat collector

Kevin Pettijohn d2fbeeb3c3 Added loadavg collector for solaris 
It seems solaris prefers "sys/loadavg.h" over "stdlib.h" when
fetching the load average.

For Illumos based OSes it was required to include "sys/time.h" to
ensure that "hrtime_t" was defined.

https://www.illumos.org/issues/6002

It also required setting the ldflags "-fno-stack-protector -lssp" to
avoid undefined symbols when linking with gcc.

/opt/local/go/pkg/tool/solaris_amd64/link: running gcc failed: exit status 1
Undefined                       first referenced

that other ones will fail.

Ed Schouten a696830c38 Add a collector for NFS client statistics. 
This change adds a new collector called "nfs" that parses the contents
of /proc/net/rpc/nfs and turns it into metrics. It can be used to
inspect the number of operations per type, but also to keep an eye on an
extraneous number of retransmissions, which may indicate connectivity
issues.

I've picked the name "nfs", as most operating systems use "nfs" for the
client component and "nfsd" as the server component. If we want to add
stats for the NFS server as well, we'd better call such a collector
"nfsd".
