7e41a2b279 Ignore /var/lib/docker by default. (#814)
The node exporter runs unprivileged, so it cannot statfs any filesystems
under this directory causing log spam.  In addition there tends to be
high churn in the filesystems here (as it's basically application
monitoring) which can cause high cardinaltiy and in one case caused
Prometheus's index symbol table to get very large.
Accordingly this should be ignored to reduce log spam and avoid
performance issues. The filesystems themselves can in principle be
monitored via container oriented exporters, and the underlying
filesystems will still be monitored.

* Improve stat linux metric names.

cpu is no longer used.

* node_cpu -> node_cpu_seconds_total for Linux

* Improve filesystem metric names with units

* Improve units and names of linux disk stats

Remove sector metrics, the bytes metrics cover those already.

* Infiniband counters should end in _total

* Improve timex metric names, convert to more normal units.

See
3c073991eb/kernel/time/ntp.c (L909)
for what stabil means, looks like a moving average of some form.

* Update test fixture

* For meminfo metrics that had "kB" units, add _bytes

* Interrupts counter should have _total

a8d7d1101a cpu: Support processor-less (memory-only) NUMA nodes (#734)
* cpu: Support processor-less (memory-only) NUMA nodes

Processor-less (memory-only) NUMA nodes exist e.g. in systems that use
Intel Optane drives for RAM expansion using Intel Memory Drive
Technology (IMDT).

IMDT RAM expansion supports two modes:

* "Unify Remote Memory domains": present a processor-less (memory-only)
  NUMA domain, which is the default
* "Expand local memory domains": to expand each processor’s memory domain
  with a portion of the memory made available by Optane and IMDT

This commit fixes a crash in the first case (when "cpulist" is empty).

Here's an example of such a system:

$ numastat -m|head -n5

3762191e66 Add timex collector (#664)
This collector is based on adjtimex(2) system call.  The collector returns
three values, status if time is synchronised, offset to remote reference,
and local clock frequency adjustment.

Values are taken from kernel time keeping data structures to avoid getting
involved how the synchronisation is implemented.  By that I mean one should
not care if time is update using ntpd, systemd.timesyncd, ptpd, and so on.
Since all time sync implementation will always end up telling to kernel what
is the status with time one can simply omit the software in between, and
look results of the syncing.  As a positive side effect this makes collector
very quick and conceptually specific, this does not monitor availability of
NTP server, or network in between, or dns resolution, and other unrelated
but necessary things.

Minimum set of values to keep eye on are the following three:

    The node_timex_sync_status tells if local clock is in sync with a remote
    clock.  Value is set to zero when synchronisation to a reliable server
    is lost, or a time sync software is misconfigured.

    The node_timex_offset_seconds tells how much local clock is off when
    compared to reference.  In case of multiple time references this value
    is outcome of RFC 5905 adjustment algorithm.  Ideally offset should be
    close to zero, and it depends about use case how large value is
    acceptable.  For example a typical web server is probably fine if offset
    is about 0.1 or less, but that would not be good enough for mobile phone
    base station operator.

    The node_timex_freq tells amount of adjustment to local clock tick
    frequency.  For example if offset is one second and growing the local
    clock will need instruction to tick quicker.  Number value itself is not
    very important, and occasional small adjustments are fine.  When
    frequency is unusually in stable one can assume quality of time stamps
    will not be accurate to very far in sub second range.  Obviously
    explaining why local clock frequency behaves like a passenger in roller
    coaster is different matter.  Explanations can vary from system load, to
    environmental issues such as a machine being physically too hot.

Rest of the measurements can help when debugging.  If you run a clock server
do probably want to collect and keep track of everything.

c169b4b1c5 Add metrics from SNTPv4 packet to ntp collector & add ntpd sanity check (#655)
* Add metrics from SNTPv4 packet to ntp collector & add ntpd sanity check

1. Checking local clock against remote NTP daemon is bad idea, local
ntpd acting as a  client should do it better and avoid excessive load on
remote NTP server so the collector is refactored to query local NTP
server.

2. Checking local clock against remote one does not check local ntpd
itself. Local ntpd may be down or out of sync due to network issues, but
clock will be OK.

3. Checking NTP server using sanity of it's response is tricky and
depends on ntpd implementation, that's why common `node_ntp_sanity`
variable is exported.

* `govendor add golang.org/x/net/ipv4`, it is dependency of github.com/beevik/ntp

* Update github.com/beevik/ntp to include boring SNTP fix

* Use variable name from RFC5905

* ntp: move code to make export of raw metrics more explicit

* Move NTP math to `github.com/beevik/ntp`

* Make `golint` happy

* Add some brief docs explaining `ntp` #655 and `timex` #664 modules

* ntp: drop XXX comment that got its decision

* ntp: add `_seconds` suffix to relevant metrics

* Better `node_ntp_leap` comment

* s/node_ntp_reftime/node_ntp_reference_timestamp_seconds/ as requested by @discordianfish
