This update for netdata fixes the following issues:
- Update to 1.29.3 Release v1.29.3 is a patch release to improve the
stability of the Netdata Agent. We discovered a bug that when
proc.plugin attempts to collect the
operstate parameter for a virtual network interface. If the chart is
obsoleted, the Netdata Agent crashes. This release also contains
additional bug fixes and improvements. Bug fixes
* Fix proc.plugin to invalidate RRDSETVAR pointers on obsoletion.
- Update to 1.29.2 Release v1.29.2 is a patch release to improve the
stability of the Netdata Agent. We discovered that an improvement
introduced in v1.29.0 could inadvertently set all os_* host labels to
unknown, which could affect users who leverage these host labels to
organize their nodes, deploy health entities, or export metrics to
external time-series databases. This bug has been fixed. This release
also contains additional bug fixes and improvements. Improvements
* Make the Opsgenie API URL configurable.
* Add k8s_cluster_id host label.
* Enable apps.plugin aggregation debug messages.
* Add configuration parameter to disable stock alarms.
* Add ACLK proxy setting as host label.
* Add freeswitch to apps_groups.conf.
* Simplify thread creation and remove unnecessary variables in the eBPF
plugin. Bug fixes
* Fix the context filtering on the data query endpoint.
* Fix container/host detection in the system-info.sh script.
* Add a small delay to the ipv4_tcp_resets alarms.
* Fix collecting operstate for virtual network interfaces.
* Fix sendmail unrecognized option F error.
* Fix so that raw binary data should never be printed.
* Change KSM memory chart type to stacked.
* Allow the REMOVED alarm status via ACLK if the previous status was
* Reduce excessive logging in the ACLK.
- Changes in 1.29.1 Release v1.29.1 is a hotfix release to address a crash
in the Netdata Agent. A locking bug in one of the internal collectors in
Netdata could cause it to crash during shutdown in a way that would
result in the Netdata Agent taking an excessively long time to exit. Bug
* Fix crash during shutdown of cgroups internal plugin.
- Update to 1.29.0 (go.d.plugin 0.27.0) The v1.29.0 release of the Netdata
Agent is a maintenance release that brings incremental but necessary
improvements that make your monitoring experience more robust. We've
pushed improvements and bug fixes to the installation and update
scripts, enriched our library of collectors, and focused on fixing bugs
reported by the community. At a glance Netdata now collects and
meaningfully organizes metrics from both the Couchbase JSON document
database and the nginx-module-vts module for exposing metrics about
NGINX virtual hosts. We've also migrated more collectors from Python to
Go in our continued efforts to make data collection faster and more
robust. The newest effort includes our Redis, Pika, and Energi Core
Wallet collectors. On the dashboard, we improved the responsiveness of
panning forward and backward through historical metrics data by
preventing unnecessary updates and reducing the number of calls. The
charts should also now immediately update when you stop panning.
* Reduce the number of alarm updates on ACLK.
* Remove unused entries from structures.
* Improve the retry/backoff during claiming.
* Support multiple chart label keys in data queries.

- Update to v1.28 Release v1.28.0 is a hotfix release to address a
deadlock in the Netdata Agent. If the Agent-Cloud link (ACLK) connection
drops and the Agent fails to queue an on_connect message, it also fails

properly freeze charts that were outside of the browser's viewport. If a
user who loaded many charts by scrolling through the dashboard, charts
outside of their browser's viewport continued updating. This excess
of chart updates caused all charts to update more slowly than every

- Update to v1.14.0 The release introduces major additions to Kubernetes
monitoring, with tens of new charts for Kubelet, kube-proxy and coredns
metrics, as well as significant improvements to the netdata helm chart.
Two new collectors were added, to monitor Docker hub and Docker engine
metrics. Finally, v1.14 adds support for version 2 cgroups, OpenLDAP
over TLS, NVIDIA SMI free and per process memory and configurable syslog
facilities. Bug Fixes:
* Fixed problem autodetecting failed jobs in python.d plugin. It now
properly restarts jobs that are being rechecked, as soon as they are
able to run.
* CouchdDB monitoring would stop sometimes with an exception. Fixed the
unhandled exception causing the issue.
* The netdata api deliberately returned http error 400 when netdata ran
in memory mode none. Modified the behavior to return responses,
regardless of the memory mode
* The python.d plugin sometimes does not receive SIGTERM when netdata
exits, resulting in zombie processes. Added a heartbeat so that the
process can exit on SIGPIPE.
* The new SMS Server Tools notifications did not handle errors well,
resulting in cryptic error messages. Improved error handling.
* Fix segmentation fault in streaming, when two dimensions had similar
* Kubernetes Helm Chart: Fixed incorrect use of namespaces in
ServiceAccount and ClusterRoleBinding RBAC fixes.
* Elastic search: The option to enable HTTPS was not included in the
config file, giving the erroneous impression that HTTPS was not
supported. The option was added.

support all possible option. Added option to connect to a PostreSQL
instance by defining a connection string (URI).
* python.d.plugin: There was no way to delete obsolete dimensions in
charts created by the python.d plugin. The plugin can now delete
dimension at runtime.
* netdata supports sending its logs to Syslog, but the facility was
hard-coded. We now support configurable Syslog facilities in
* Kubernetes Helm Chart improvements:
+ Added serviceName in statefulset spec to align with the k8s
+ Added preStart command to persist slave machine GUIDs, so that pod
deletion/addition during upgrades doesn't lose the slave history.

+ Added preStop command to wait for netdata to exit gracefully before
removing the container
+ Extended configuration file support to provide more control from the
helm command line
+ Added option to disable Role-based access control
+ Added liveness and readiness probes.
- Update to v1.13.0 netdata has taken the first step into the world of
Kubernetes, with a beta version of a Helm chart for deployment to a k8s
cluster and proper naming of the cgroup containers. We have big plans
for Kubernetes, so stay tuned! A major refactoring of the python.d
plugin has resulted in a dramatic decrease of the required memory,
making netdata even more resource efficient. We also added charts for
IPC shared memory segments and total memory used. Improvements:
* Kubernetes: Helm chart and proper cgroup naming

* 7 new data collectors and 11 rewrites of existing data collectors for
* A new management API for all netdata servers
* Bind different functions of the netdata APIs to different ports
Management API: Netdata now has a management API. We plan to provide a
of configuration commands using this API. In this release, the
management API supports disabling or silencing alarms during
maintenance periods. For more information about the management API,
Anonymous statistics: Anonymous usage information can be collected and
sent to Google Analytics. This functionality is disabled by default in
openSUSE. Remove /etc/netdata/.opt-out-from-anonymous-statistics to
enable. The statistics calculated from this information will be used
for: 1. Quality assurance, to help us understand if netdata behaves as
expected and help us identify repeating issues for certain
distributions or environment. 2. Usage statistics, to help us focus on
the parts of netdata that are used the most, or help us identify the
extend our development decisions influence the community. Information
is sent to Netdata via two different channels:
* Google Tag Manager is used when an agent's dashboard is accessed.
* The script anonymous-statistics.sh is executed by the Netdata daemon,
when Netdata starts, stops cleanly, or fails. Both methods are
controlled via the same opt-out mechanism. For more information, check
https://docs.netdata.cloud/docs/anonymous-statistics/ Data collection:
This release introduces a new Go plugin orchestrator. This plugin has
its own github repo (https://github.com/netdata/go-orchestrator). It
is open-source, using the same license and we welcome contributions.
The orchestrator can also be used to build custom data collection
plugins written in Go. We have used the orchestrator to write many new
Go plugins in our go.d plugin github repo. For more information, check
* Activemq (Go)
* Consul (Go)
* Lighttpd2 (Go)
* Solr (Go)
* Springboot2 (Go)
* mdstat - nonredundant arrays (C)
* CUPS printing system (C) High performance versions of older data
* apache (Go)

- Update to v1.11.1 Improved internal database: Overflown incremental
values (counters) do not show a zero point at the charts. Netdata
detects the width (8bit, 16bit, 32bit, 64bit) of each counter and
properly calculates the delta when the counter overflows. The internal
database format has been extended to support values above 64bit. New
data collection plugins:
* openldap, to collect performance statistics from OpenLDAP servers.
* tor, to collect traffic statistics from Tor.
* nvidia_smi to monitor NVIDIA GPUs. Improved data collection plugins:
* BUG FIX: network interface names with colon (:) in them were
incorrectly parsed and resulted in faulty data collection values.
* BUG FIX: smartd_log has been refactored, has better python v2
compatibility, and now supports SCSI smart attributes
* cpufreq has been re-written in C - since this module if common, we
decided to convert to an internal plugin to lower the pressure on the
python ones. There are a few more that will be transitioned to C in
the next release.
* BUG FIX: sensors got some compatibility fixes and improved handling
for lm-sensors errors. Health monitoring:
* BUG FIX: max network interface speed data collection was faulty, which
resulted in false-positive alarms on systems with multiple interfaces
using different speeds (the speed of the first network interface was
used for all network interfaces). Now the interface speed is shown as
* alerta.io notifications got a few improvements
* BUG FIX: conntrack_max alarm has been restored (was not working due to
an invalid variable name referenced) Registry (my-netdata menu):
* It has been refactored a bit to reveal the URLs known for each node
and now it supports deleting individual URLs.
- Update to 1.11.0
* Stock config files are now in /usr/lib/netdata; use the
/etc/netdata/edit-config script to copy and edit them.
* The query engine of netdata has been re-written to support query
plugins. We have already added the following algorithms that are
available for alarm, charts and badges:
+ stddev, for calculating the standard deviation on any time-frame.
+ ses or ema or ewma, for calculating the exponential weighted moving
average, or single/simple exponential smoothing on any time-frame.
+ des, for calculating the double exponential smoothing on any
+ cv or rsd, for calculating the coefficient of variation for any
time-frame. Fixed security issues:
* CVE-2018-18836 Fixed JSON Header Injection (an attacker could send \n
encoded in the request to inject a JSON fragment into the response).
* CVE-2018-18837 Fixed HTTP Header Injection (an attacker could send \n
encoded in the request to inject an HTTP header into the response).
* CVE-2018-18838 Fixed LOG Injection (an attacker could send \n encoded
in the request to inject a log line at access.log). boo#1139098
* CVE-2018-18839 Not fixed Full Path Disclosure, since these are
intended (netdata reports the absolute filename of web files, alarm
config files and alarm handlers).
* Fixed Privilege Escalation by manipulating apps.plugin or
cgroup-network error handling.
* Fixed LOG injection (by sending URLs with \n in them). New data
* rethinkdbs for monitoring RethinkDB performance
* proxysql for monitoring ProxySQL performance
* litespeed for monitoring LiteSpeed web server performance.

* linux_power_supplies for monitoring Linux Power Supplies attributes
Data collection orchestrators changes:
* node.d.plugin does not use the js command any more.
* python.d.plugin now uses monotonic clocks. There was a discrepancy in
clocks used in netdata that resulted in a shift in time of python
module after some time (it was missing 1 sec per day).
* added MySQLService for quickly adding plugins using mysql queries.
* URLService now supports self-signed certificates and supports custom
* all python.d.plugin modules that require sudo to collect metrics, are
now disabled by default, to avoid security alarms
on installations that do not need them. Improved data collection
* apps.plugin now detects changes in process file descriptors, also
fixed a couple of memory leaks. Its default configuration has been
enriched significantly, especially for IoT.
* freeipmi.plugin now supports option ignore-status to ignore the status
reported by given sensors.
* statsd.plugin (for collecting custom APM metrics)
+ The charting thread has been optimized for lowering its CPU
consumption when several millions of metrics are collected.
+ sets now report zeros instead of gaps when no data are collected
+ histograms and timers have been optimized for lowering their CPU
consumption to support several thousands of such metrics are
+ histograms had wrong sampling rate calculations.
+ gauges now ignore sampling rate when no sign is included in the
+ the minimum sampling rate supported is now 0.001.
+ netdata statsd is now drop-in replacement for datadog statsd
(although statsd tags are currently ignored by netdata).
* proc.plugin (Linux, system monitoring)
+ Unused interrupts and softirqs are not used in charts (this saves
quite some processing power and memory on systems with dozens of CPU
+ fixed /proc/net/snmp parsing of IcmpMsg lines that failed on a few
+ Veritas Volume Manager disks are now recognized and named
+ Now netdata collects TcpExtTCPReqQFullDrop and re-organizes metrics
in charts to properly monitor the TCP SYN queue and the TCP Accept
queue of the kernel.
+ Many charts that were previously reported as IPv4, were actually
reflecting metrics for both IPv4 and IPv6. They have been renamed to
+ netdata now monitors SCTP.
+ Fixed BTRFS over BCACHE sector size detection.
+ BCACHE data collection is now faster.
+ /proc/interrupts and /proc/softirqs parsing fixes.
* diskspace.plugin (Linux, disk space usage monitoring)
+ It does not stat() excluded mount points any more (it was
interfering with kerberos authenticated mount points).
+ several filesystems are now by default excluded from disk-space
monitoring, to avoid breaking suspend on workstations.
* python.d.plugin PYTHON modules (applications monitoring)
+ web_log module now supports virtual hosts, reports http/https
metrics, support squid logs
+ nginx_plus module now handles non-continuous peer IDs
+ ipfs module is optimized, the use of its Pin API is now disabled by
default and can enabled with a netdata module
option (using the IPFS Pin API increases the load on the IPFS
+ fail2ban module now supports IPv6 too.
+ ceph module now checks permissions and properly reports issues
+ elasticsearch module got better error handling

* charts.d.plugin BASH modules
+ nut now supports naming UPSes. Health monitoring:
* Added variable $system.cpu.processors.

* New notification methods:
+ Microsoft Teams
+ Amazon SNS Backends:
* Host tags are now sent to Graphite
* Host variables are now sent to Prometheus Streaming:
* Each netdata slave and proxy now filter the charts that are streamed.
This allows exposing netdata masters to third parties by limiting the
number of charts available at the master.
* Fixed a bug in streaming slaves that randomly prevented them to resume
streaming after network errors.
* Fixed a bug that on slaves that sent duplicated chart names under
* Fixed a bug that caused slaves to consume 100% CPU (due to a misplaced
lock) when multiple threads were adding dimensions
