* mountstats: Use new NFS protocol field
In https://github.com/prometheus/procfs/pull/100, the NFSTransportStats
struct was expanded by a field called protocol that specifies the NFS
protocol in use, either "tcp" or "udp". This commit adds the protocol as
a label to all NFS metrics exported via the mountstats collector.

* cpu: Add a 2nd label 'package' to metric node_cpu_core_throttles_total
This commit fixes the node_cpu_core_throttles_total metrics on
multi-socket systems as the core_ids are the same for each package.
I.e. we need to count them seperately.
Rename the node_package_throttles_total metric label `node` to `package`.
Reorganize the sys.ttar archive and use the same symlinks as the Linux
kernel. Also, the new fixtures now use a dual-socket dual-core cpu w/o
HT/SMT (node0: cpu0+1, node1: cpu2+3) as well as processor-less
(memory-only) NUMA node 'node2' (this is a very rare case).

* cpu: Use the direct /sys path to the cpu files.
Use the direct path /sys/devices/system/cpu/cpu[0-9]* (without symlinks)
instead of /sys/bus/cpu/devices/cpu[0-9]*.
The latter path also does not exist e.g. on RHEL 6.9's kernel.

Netstat is 40% of the metrics on my laptop, many of which
are highly detailed information about IP internals in the kernel.
~300 such metrics on every machine in your fleet is excessive,
so focus on key metrics by default, overridable by the user.

* All collectors drop the `cpu` prefix for `cpu` label values.
* Fix subsystem string in cpu_freebsd.

* Improve filesystem metric names with units

Remove sector metrics, the bytes metrics cover those already.
* Infiniband counters should end in _total

* For meminfo metrics that had "kB" units, add _bytes
* Interrupts counter should have _total
Linux "guest" metrics for VMs are already accounted for in node_cpu
`user` and `nice` metrics. Separate these into their own metric to
avoid duplication of data.
* cpu: Metric 'package_throttles_total' is per package.
'package_throttles_total' is per package, not per cpu. This also reduces
the total number of cpu time series a lot (esp for multi core cpus).
* cpu: Better handling of a cpulist edge-case.
* cpu: Extract the package number from the directory name.
Do not rely on the range index.
* cpu: Add package_throttle_count for node0 cpu1
This file must be ignored by the cpu collector.
* Add bcache collector for Linux
This collector gathers metrics related to the Linux block cache
(bcache) from sysfs.
* Removed commented out code
* Use project comment style
* Add _sectors to metric name to indicate unit
* Really use project comment style
* Rename bcache.go to bcache_linux.go
* Keep collector namespace clean
Rename:
- metric -> bcacheMetric
- periodStatsToMetrics -> bcachePeriodStatsToMetric
* Shorten slice initialization
* Change label names to backing_device, cache_device
* Remove five minute metrics (keep only total)
* Include units in additional metric names
* Enable bcache collector by default
* Provide metrics in seconds, not nanoseconds
* remove metrics with label "all"
* Add fixtures, update end-to-end for bcache collector
* Move fixtures/sys into tar.gz
This changeset moves the collector/fixtures/sys directory into
collector/fixtures/sys.tar.gz and tweaks the Makefile to unpack the
tarball before tests are run.
The reason for this change is that Windows does not allow colons in a
path (colons are present in some of the bcache fixture files), nor can
it (out of the box) deal with pathnames longer than 260 characters
(which we would be increasingly likely to hit if we tried to replace
colons with longer codes that are guaranteed not the turn up in regular
file names).
* Add ttar: plain text archive, replacement for tar
This changeset adds ttar, a plain text replacement for tar, and uses it
for the sysfs fixture archive. The syntax is loosely based on tar(1).
Using a plain text archive makes it possible to review changes without
downloading and extracting the archive. Also, when working on the repo,
git diff and git log become useful again, allowing a committer to verify
and track changes over time.
The code is written in bash, because bash is available out of the box on
all major flavors of Linux and on macOS. The feature set used is
restricted to bash version 3.2 because that is what Apple is still
shipping.
The programm also works on Windows if bash is installed. Obviously, it
does not solve the Windows limitations (path length limited to 260
characters, no symbolic links) that prompted the move to an archive
format in the first place.
* Add qdisc collector for Linux
This collector gathers basic queueing discipline metrics via netlink,
similarly to what `tc -s qdisc show` does.
* qdisc collector: nl-specific code moved, names fixed
- netlink-specific parts moved to github.com/ema/qdisc
- avoid using shortened names
- counters renamed into XXX_total
* Get rid of parseMessage error checking leftover
* Add github.com/ema/qdisc to vendored packages
* Update help texts and comments
* Add qdisc collector to README file
* qdisc collector end-to-end testing
* Update qdisc dependency to latest version
Update github.com/ema/qdisc dependency to revision 2c7e72d, which
includes unit testing.
* qdisc collector: rename "iface" label into "device"
According to Mellanox, it is standard practice that the port_xmit_data and port_rcv_data
files are split into 4 lanes. To get the actual transmit and receive values for each
port, the metric needs to be multiplied by 4.
