Robert Clark 3a5917dfdc Add support for legacy InfiniBand drivers 
Older versions of the OFED drivers contain 64-bit variants of the port counters and are located in a directory named 'counters_ext'. This patch includes these older metrics that have since been deprecated with OFED 4.0.

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.

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.

Bjørn Forsman 64e637cbcc Ignore autofs filesystems on linux

filesystem on every scrape. This is undesirable. Better ignore autofs.

The underlying filesystem that autofs mounts will be monitored though,
when the (real) filesystem is mounted.

A collector for DRBD
 2016-12-25 11:04:43 +01:00
Ed Schouten b0d15eaac6 Reduce the severity of these messages. 
They get printed all the time, as there are some tokens in the /proc
file that we simply don't support. It's better to keep these as
debugging messages, which may come in useful if new tags start to
appear.

- Use the right number of printf() arguments. Use %q where it makes sense.
- Use "DRBD" instead of "Drbd", per Go's style guide.
- Add _total suffixes to counter metrics.
- Mention the unit (bytes) in documentation strings once more.

Ed Schouten 6269f7502a Add a collector for DRBD. 
This collector exposes most of the useful information that can be found

kibibytes.

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".

Jonas Wielicki c481dd19da Re-introduce human-readable chip types 
The chip label generation has been changed in #334 to prefer the
unique device path (e.g. the location on the PCI bus) due to #333.

Here, a new annotation metric ``node_hwmon_chip_names`` is
introduced which allows to link the unique chip sysfs path to a
human-readable chip name which may not be unique among chip sysfs
paths (for example, dual-slot systems have multiple
chipType="coretemp" sensors).

This allows to mitigate the downsides of the solution to #333
(namely that the device path may not be stable across kernels and
reboots) for cases where it does not matter that multiple devices
may have the same human-readable name (e.g. aggregation or where
at most one device with a common chip name is present).

For cases where no human-readable name can be derived, the
annotation metric is not emitted.

Ed Schouten 9749c2c0b3 mdstat: Fix parsing of RAID0 lines that contain additional attributes. 
We seem to have a small number of Linux servers here that have lines in
/proc/mdstat that cannot be parsed by the node exporter, due to them
containing attributes that are not matched by the regular expression
("super 1.2").

Extend the regular expression to skip this data, just like we do for all
of the other status lines.

Rene Treffer abe8e297a6 Prefer device path based names over exported names (#334) 
* Prefer device path based names over exported names

For some sensors (like coretemp) it is possible that multiple
instances exist, thus base the name on the device path and not on
the exported name.

* Update end-to-end test for dual socket machines

Explicitly have 2 coretemp instances with a symlink for the device
such that the hwmon collector must pick that name (or fail)

systimer_freq can be extracted from following
