## master / unreleased * [CHANGE] * [FEATURE] * [ENHANCEMENT] * [BUGFIX] ## 0.16.0-rc.0 / 2018-03-08 **Breaking changes** This release contains major breaking changes to metric names. Many metrics have new names, labels, and label values in order to conform to current naming conventions. * Linux node_cpu metrics now break out `guest` values into separate metrics. See Issue #737 * Many counter metrics have been renamed to include `_total`. * Many metrics have been renamed/modified to include base units, for example `node_cpu` is now `node_cpu_seconds_total`. In order to help with backwards compatibility, a `metric_relabel_config` is being worked on to allow for easier transition of metric names. See: https://github.com/prometheus/node_exporter/issues/830 Other breaking changes: * The megacli collector has been removed, is now replaced by the storcli.py textfile helper. * The textfile collector will now treat timestamps as errors. * [CHANGE] Split out guest cpu metrics on Linux. #744 * [CHANGE] Exclude Linux proc from filesystem type regexp #774 * [CHANGE] Ignore more virtual filesystems #775 * [CHANGE] Remove obsolete megacli collector. #798 * [CHANGE] Ignore /var/lib/docker by default. #814 * [CHANGE] Cleanup NFS metrics #834 * [CHANGE] Only report core throttles per core, not per cpu #836 * [CHANGE] Treat custom textfile metric timestamps as errors #769 * [CHANGE] Drop exec_ in boot_timestamp_seconds on *bsd #839 * [CHANGE] Use lowercase cpu label name in interrupts #849 * [FEATURE] Add `collect[]` parameter #699 * [FEATURE] Add text collector conversion for ipmitool output. #746 * [FEATURE] Add openbsd meminfo #724 * [FEATURE] Add systemd summary metrics #765 * [FEATURE] Add OpenBSD CPU collector #805 * [FEATURE] Add NFS Server metrics collector. #803 * [FEATURE] add sample directory size exporter #789 * [ENHANCEMENT] added Wear_Leveling_Count attribute to smartmon.sh script #707 * [ENHANCEMENT] Simplify Utsname string conversion #716 * [ENHANCEMENT] apt.sh: handle multiple origins in apt-get output #757 * [ENHANCEMENT] Export systemd timers last trigger seconds. #807 * [ENHANCEMENT] updates for zfsonlinux 0.7.5 #779 * [BUGFIX] Fix smartmon.sh textfile script #700 * [BUGFIX] netdev: Change valueType to CounterValue #749 * [BUGFIX] textfile: fix duplicate metrics error #738 * [BUGFIX] Fix panic by updating github.com/ema/qdisc dependency #778 * [BUGFIX] Use uint64 in the ZFS collector #714 * [BUGFIX] multiply page size after float64 coercion to avoid signed integer overflow #780 * [BUGFIX] smartmon: Escape double quotes in device model family #772 * [BUGFIX] Fix log level regression in #533 #815 * [BUGFIX] Correct the ClocksPerSec scaling factor on Darwin #846 ## 0.15.2 / 2017-12-06 * [BUGFIX] cpu: Support processor-less (memory-only) NUMA nodes #734 ## 0.15.1 / 2017-11-07 * [BUGFIX] xfs: expose correct fields, fix metric names #708 * [BUGFIX] Correct buffer_bytes > INT_MAX on BSD/amd64. #712 * [BUGFIX] netstat: return nothing when /proc/net/snmp6 not found #718 * [BUGFIX] Fix off by one in Linux interrupts collector #721 * [BUGFIX] Add and use sysReadFile in hwmon collector #728 ## 0.15.0 / 2017-10-06 **Breaking changes** This release contains major breaking changes to flag handling. * The flag library has been changed, all flags now require double-dashs. (`-foo` becomes `--foo`). * The collector selection flag has been replaced by individual boolean flags. * The `-collector.procfs` and `-collector.sysfs` flags have been renamed to `--path.procfs` and `--path.sysfs` respectively. The `ntp` collector has been replaced with a new NTP-based check that is designed to expose the state of a localhost NTP server rather than provide the offset of the node to a remote NTP server. By default the `ntp` collector is now locked to localhost. This is to avoid accidental spamming of public internet NTP pools. Windows support is now removed, the [wmi_exporter](https://github.com/martinlindhe/wmi_exporter) is recommended as a replacement. * [CHANGE] `node_cpu` metrics moved from `stats` to `cpu` collector on linux (enabled by default). #548 * [CHANGE] Blacklist systemd scope units #534 * [CHANGE] Remove netbsd/arm #551 * [CHANGE] Remove Windows support #549 * [CHANGE] Enable IPVS collector by default #623 * [CHANGE] Switch to kingpin flags #639 * [CHANGE] Replace --collectors.enabled with per-collector flags #640 * [FEATURE] Add ARP collector for Linux #540 * [FEATURE] Add XFS colector for Linux #568, #575 * [FEATURE] Add qdisc collector for Linux #580 * [FEATURE] Add cpufreq stats for Linux #548 * [FEATURE] Add diskstats for Darwin #593 * [FEATURE] Add bcache collector for Linux #597 * [FEATURE] Add parsing /proc/net/snmp6 file for Linux #615 * [FEATURE] Add timex collector for Linux #664 * [ENHANCEMENT] Include overal health status in smartmon.sh example script #546 * [ENHANCEMENT] Include `guest_nice` in CPU collector #554 * [ENHANCEMENT] Add exec_boot_time for freebsd, dragonfly #550 * [ENHANCEMENT] Get full resolution for node_time #555 * [ENHANCEMENT] infiniband: Multiply port data XMIT/RCV metrics by 4 #579 * [ENHANCEMENT] cpu: Metric 'package_throttles_total' is per package. #657 * [BUGFIX] Fix stale device error metrics #533 * [BUGFIX] edac: Fix typo in node_edac_csrow_uncorrectable_errors_total #564 * [BUGFIX] Use int64 throughout the ZFS collector #653 * [BUGFIX] Silently ignore nonexisting bonding_masters file #569 * [BUGFIX] Change raid0 status line regexp for mdadm collector (bug #618) #619 * [BUGFIX] Ignore wifi collector permission errors #646 * [BUGFIX] Always try to return smartmon_device_info metric #663 ## 0.14.0 / 2017-03-21 NOTE: We are deprecating several collectors in this release. * `gmond` - Out of scope. * `megacli` - Requires forking, to be moved to textfile collection. * `ntp` - Out of scope.
