* 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.

The `node_cpu_info` metric contains some information like the `model`
(which is an integer), but not the human readable model name. Also the
stepping of the processor might be interesting, since different stepping
of a processor might behave differently.

With a bond interface the state of the slave interface from the bond's
point of view is reflected in `mii_status` and is independent of the
link's `operstate`.
When a bond is monitored with `miimon`, `mii_status` will reflect the
state of the physical link as configured via the operator.
When a bond is monitored via `arp_interval` the `mii_status` will
reflect the results of the bond ARP checking. This means the link can
be down from the bond's point of view, but up from a physical
connection point of view.
If a bond is not monitored via miimon or arp, the `mii_status` should
likely be always `up`, however I have observed a case where this is not
true and the `operstate` is `up` while `mii_status` is `down`. Kernel
bond documentation stresses that a bond should not be configured without
one of `mii_mon` or `arp_interval` configured however.
This change results in the metric 'node_bonding_active' matching the
up/down state of the bond's point of view rather than operstate.

Vmstat has over 100 fields, most of which are highly
detailed debug information. Trim this down to only
essential fields by default, configurable by flag.

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: 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).

* cpu: rename some variables (pkg => node)
* cpu: Use %v not %q in log.Debugf() format strings
* 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.

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.

Add new metrics for the InfiniBand network protocol including the amount of packets sent and received, the number of times the link has been downed and how many times the link has recovered from an error state.

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.
- 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.
This collector exposes most of the useful information that can be found
in /proc/drbd. Sizes are normalised to be in bytes, as /proc/drbd uses
kibibytes.
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".
