This test runs a selection of collectors against the fixtures and
compares the output to a reference.
The uname and filesystem collectors are disabled because they use system
calls that cannot be fixtured easily.
Remove all hardcoded references to `/proc`. For all collectors that do
not use `github.com/prometheus/procfs` yet, provide a wrapper to
generate the full paths.
Reformulate help strings, errors and comments to remove absolute
references to `/proc`.
This is a breaking change: the `-collector.ipvs.procfs` flag is removed
in favor of the general flag. Since it only affected that collector it
was only useful for development, so this should not cause many issues.
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

Updated sockstat to return TCP and UDP memory in bytes instead of page count
Collects more information for labelling scraped filesystems with the device
and fsType. This is useful for setting alerts which should change based on
filesystem type, or for filtering out shared mounts such as with NFS volumes.
This puts all collector-specific flags into their own namespace under
"collector.<collector-name>", and moves from camel case to dashes, which
is the standard in Prometheus land now.
Fixes issue described in #38
/proc/stat reports a blank line which needs to be ignored.
Old kernels misses one CPU time field, this needs to be ignored too.
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.
This collector exposes two metrics:
- net_bonding_slaves: configured slaves per bonding interface
- net_bonding_slaves_active: currently active slaves per bonding
interface
This collector exports the following metrics:
- raid_drive_temperature: drive temperature
- raid_drive_count: drive error and event counters
- raid_adapter_disk_presence: disk presence per adapter
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.
Diskstats: Split out metrics, keep 'device' label
Meminfo: Split out metrics, one each. Convert kB to bytes.
Netstats: Split out metrics, keep 'device' label.
Interrupts: Stays the same. Not perfect, but should be rarely used.
Loadavg: Make it clear it's the 1m loadavg
Last seen: Not clear this belongs in the node exporter, as it's more a user
thing than a machine thing. Changed to absolute time rather than relative.
All stats now have appropriate counter/gauge type.
The gmond (Ganglia) exporter module exports many metrics not under our
control. They should all be prefixed in a common way to make it obvious
where they came from.
