* Add hwmon support (mainly known from lm-sensors)
This commit adds initial support for linux hardware sensors, exported
through sysfs.
Details of the interface can be found at
https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface
* Add end-to-end test with some real life data
* Cleanup comments on hwmon collector
* Drop raw sensor name from hwmon output
* Let the sensor label be "sensor"
* Add hwmon short description to README.
The option to write out a memory profile to file was removed in a730cff.
Declaring flags as local variable does not only result in cleaner, more
testable code, but also ensures that the program won't compile anymore
when unused flags are left in place.
Removes unused signal handlers left over from signal based collection
and block the non windows-relevant collectors loadavg and interrupts.
Signal based collection removed in 1c17481a42.
Enabled by default collectors are chosen for Linux, which supports all
of the implemented collectors. But for other OSes (OS X, for example)
this list is not suitable, because they lack most of those collectors.
Because of that, it is not possible to run node_exporter with default
options on such OSes. Fix this by filtering list of enabled by default
collectors based on their availability for current platform.
Closes#149

This creates a single metric like:
node_uname_info{domainname="(none)",machine="x86_64",nodename="desktop",release="3.16.0-48-generic",sysname="Linux",version="#64~14.04.1-Ubuntu SMP Thu Aug 20 23:03:57 UTC 2015"} 1
Fixed file-nr update function
Fixed file-nr test case
Fixed file-nr test case again
Fixed file-nr separator to tab
Updated file-nr to filenr.
Updated file-nr to filenr.
Fixed file-nr test cases, added comments
Remove reporting the second value from file-nr as it will alwasy be zero in linux 2.6 and greator
Renaming file-nr to filefd
Updated build constraint
Updates and code cleanup for filefd.
Updated enabledCollectors with the correct name for filefd
Fixed filefd test wording
initial work on sockstat work
Fixed package name
Finished implementation of the sockstat plugin
missed a return value
Added sockstat to default plugins to start
Fixed scanner read on sockstat
fixed sockstat linux test for TCP alloc
update sockstat test case
Updated sockstat to return TCP and UDP memory in bytes instead of page count
This allows static metrics (e.g. an attributes collector replacement),
and cronjobs to expose stats by echoing into a file.
For example:
echo "my_metric 123" > mycronjob.prom.$$
mv mycronjob.prom.$$ mycronjob.prom
Remove special tags necessary for gmond and runit collectors. All
collectors get built. Selection of which collectors to use continues to
happen via parameter.
This catches things like listen overflows, retransmits
and other things that are very useful for retroactive debugging
thus I think it's justified to have it on by default.
Switch to Update using the Collecter Collect interface, due to not knowing all
metricnames in all modules beforehand we can't use Describe and thus the full
Collecter interface.
Remove 'updates', it's meaning varies by module and doesn't add much.
Last login is disabled by default as it's broken on ubuntu 12.04
Interrupts is disabled by default as it's very granular and we'll have total interrupts from /proc/stat
Allow ignoring devices from diskstats, ignore ram and loop devices by default.
Use glog for logging.
