All tools in OpenBSD base system use swpginuse instead of swpgonly
for reporting swap usage (snmpd, swapctl, top, vmstat), so let
memory collector use that as well for consistency.
* Add overlay to defIgnoredFSTypes
To avoid statfs() errors if node_exporter is running as non privileged user.
* Updated defIngoredFSTypes values in sorted order
* Update vendor github.com/prometheus/procfs/...
* Refactor NFS collector
Use new procfs library to parse NFS client stats.
* Ignore nfs proc file not existing.
* Refactor with reflection to walk the structs.
The node exporter runs unprivileged, so it cannot statfs any filesystems
under this directory causing log spam. In addition there tends to be
high churn in the filesystems here (as it's basically application
monitoring) which can cause high cardinaltiy and in one case caused
Prometheus's index symbol table to get very large.
Accordingly this should be ignored to reduce log spam and avoid
performance issues. The filesystems themselves can in principle be
monitored via container oriented exporters, and the underlying
filesystems will still be monitored.
* Unify CPU collector conventions
Add a common CPU metric description.
* All collectors use the same `nodeCpuSecondsDesc`.
* All collectors drop the `cpu` prefix for `cpu` label values.
* Fix subsystem string in cpu_freebsd.
* Fix Linux CPU freq label names.
* Improve stat linux metric names.
cpu is no longer used.
* node_cpu -> node_cpu_seconds_total for Linux
* Improve filesystem metric names with units
* Improve units and names of linux disk stats
Remove sector metrics, the bytes metrics cover those already.
* Infiniband counters should end in _total
* Improve timex metric names, convert to more normal units.
See
3c073991eb/kernel/time/ntp.c (L909)
for what stabil means, looks like a moving average of some form.
* Update test fixture
* For meminfo metrics that had "kB" units, add _bytes
* Interrupts counter should have _total
* Move FreeBSD/DragonflyBSD out of meminfo add kvm.
This gives us SwapUsed, and everything under one roof.
* Fix typos per review.
* Update to use newer API.
* Remove premature optimization per PR feedback.
* Implements meminfo collector for OpenBSD
This is a rework of #151.
* Fix CGO import
* Add some useful metrics
* Rename total -> size for normalization
* remove injection hook for textfile metrics, convert them to prometheus format
* add support for summaries
* add support for histograms
* add logic for handling inconsistent labels within a metric family for counter, gauge, untyped
* change logic for parsing the metrics textfile
* fix logic to adding missing labels
* Export time and error metrics for textfiles
* Add tests for new textfile collector, fix found bugs
* refactor Update() to split into smaller functions
* remove parseTextFiles(), fix import issue
* add mtime metric directly to channel, fix handling of mtime during testing
* rename variables related to labels
* refactor: add default case, remove if guard for metrics, remove extra loop and slice
* refactor: remove extra loop iterating over metric families
* test: add test case for different metric type, fix found bug
* test: add test for metrics with inconsistent labels
* test: add test for histogram
* test: add test for histogram with extra dimension
* test: add test for summary
* test: add test for summary with extra dimension
* remove unnecessary creation of protobuf
* nit: remove extra blank line
It might happen that a given upgrade comes from multiple origins, in
which case the origins are separated by ", " and thus breaking
whitespace-based split. For example:
Inst package [1.2.3] (1.2.4 Debian:8.10/oldstable, Debian-Security:8/oldstable [amd64])
To workaround this case, mangle the apt-get output to remove whitespaces from
the origins list.
* Added text collector conversion for ipmitool output.
* Sort metrics before exporting, add namespace.
* Added HELP string, tidy up a bit.
* Make status a gauge.
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.
