Thorhallur Sverrisson 492c96f6b6 Moving buddyinfo_test.go to procfs library 2017-02-15 10:15:43 -06:00
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.

Ben Kochie 5a6db5c8d2 Handle multiple NFS device mounts 
It's possible to mount an NFS share in multiple locations.
* Duplicates contain the same metric values, so they can be ignored.

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
devstat_getstats. In particular, it allocates and resizes memory
referenced by devinfo.

Dominik Honnef ea55d0f5cb Don't race in FreeBSD devstat collector 
Querying the number of devices separately from the device list itself is
racy. Devices may be added or removed between the two calls; and removed
devices would lead to a segfault.

Dominik Honnef 20ca0f1376 Eliminate memory leak in FreeBSD devstat collector 
The memory allocated by calloc was never freed. Since the devinfo struct
never leaves the function, anyway, we might as well just allocate it on
the stack.
