Add node_softirqs_total metric (#2221)
This adds a new Linux metric, node_softirqs_total, which corresponds
to the 'softirq' line in /proc/stat. This metric is disabled by
default and it can be enabled with '--collector.stat.softirq'.

Benjamin Drung b6215e649c Add os release collector
Currently Node Exporter has a metric called `node_uname_info` which of
course exposes uname info. While this is nice, it does not help if you
are running different OSes which could have similar uname info.

Therefore parse `/etc/os-release` or `/usr/lib/os-release` and expose a
`node_os_info` metric which provide information regarding the OS
release/version of the node. Also expose the major.minor part of the OS
release version as `node_os_version`.

Since the os-release files will not change often, cache the parsed
content and only refresh the cache if the modification time changes.

This `os` collector will read files outside of `/proc` and `/sys`, but
the os-release file is widely used and the format is standardized:
https://www.freedesktop.org/software/systemd/man/os-release.html

Add flag to ignore network speed if it is unknown
Some devices (ex virtual) don't have a speed and report `-1` as the
speed value. Add a flag to allow ignoring speed on these devices.

Peter Bueschel da5972b539
Add gauges for allocated memory for queued UDP and TCP packages (#1503)
* Two new states will be added to the tcpstat collector called rx_queued_bytes and tx_queued_bytes.

For UDP datagrams an additional collector 'udp_queues' can be used to expose the total lengths of the tx_queue and rx_queue.
@SuperQ and @discordianfish this changes gives us the option to check for overloaded UDP + TCP processing.
The names of the new TCP states and the UDP metric can be discussed.
The current reasons are just:

I don't want to add another collector for the same exposed file, so I just added the new states to the tcpstat collector.
I chose the name 'udp_queue' instead of 'udpstat' as UDP has no state.

ideaship 8d90276283 Add bcache collector (#597)
* 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.
