Description: 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 WARN/CRIT. * 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 fixes * 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. Improvements * 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. * Truncate excessive information from titles for apps and cgroups collectors. * Use mguid instead of hostname in the ACLK collector list. * Cleanup and minor fixes to eBPF collector. * Add _is_k8s_node label to the host labels. * Move ACLK into a legacy subfolder. * Exclude autofs by default in the diskspace plugin. * Mark internal functions as static in health code. * Remove unused struct in health code. * Add support for per series styling for dygraphs. Dashboard * Fix minor vulnerability alert by updating socket-io dependency. * Fix dygraph panning responsiveness, chart heights and performance improvements. * Make legend position configurable. Collectors * Add Go version of the redis collector. * Add Go version of the pika collector. * Add Go version of the energis collector. * Add a new nginxvts collector. * Add a new couchbase collector. * Add Traefik v2 to the prometheus collector default configuration. * Add an expected_prefix configuration option to the prometheus collector. * Add patterns support to the filecheck collector. Bug fixes * Fix container detection from systemd-detect-virt. * Fix handling of TLS config so that cURL works in all cases. * Fix disconnect message sent via ACLK on agent shutdown * Fix prometheus remote write header * Fix values in Prometheus export for metrics, collected by the Prometheus collector * Fix handling spaces in labels values in the Prometheus collector * Fix mysql.slave_status alarm for go mysql collector * Make mdstat_mismatch_cnt alarm less strict * Dispatch cgroup discovery into another thread * Fix data source option for Prometheus web API in exporting configuration * Fix anomalies collector custom model bug * Fix broken dbengine stress tests. * Fix segmentation fault in the agent * Fix memory allocation when computing standard deviation * Fix temperature parsing in the hddtemp collector * Fix postgres password bug and change default config * Add handling "yes" and "no" and flexible space match in the python.d/fail2ban plugin * Fix spelling mistakes in the Python plugin and documentation. - 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 to properly release a lock in the web server thread. - Enable additional dependencies (gprc, json, libcurl, libelf, libwebsockets, protobuf, snappy, xenstat, yajl) - Update to v1.27.0 (go.d.plugin 0.26.2) The v1.27.0 release of the Netdata Agent brings dramatic improvements to long-term metrics storage via the database engine, and new dashboard features like a time & date picker for visualizing precise timeframes. Two new collectors bring incredible new value to existing features, including a bit of machine learning magic. This release contains 8 new collectors, 1 new notification method (2 others enhanced), 54 improvements, 41 documentation updates, and 58 bug fixes.

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 names. * 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. * RocketChat notifications were not being sent properly. Added default recipients for roles in the health alarm notification configuration. Improvements: * go.d.plugin v0.4.0 : Docker Hub and k8s coredns collectors, springboot2 URI filters support. * go.d.plugin v0.3.1 : Add default job to run k8s_kubelet.conf, k8s_kubeproxy, activemq modules * go.d.plugin v0.3.0 : Docker engine, kubelet and kub-proxy collectors. x509check module reading certs from file support * Added unified cgroup support that includes v2 cgroups * Disk stats: Added preferred disk id pattern, so that users can see the id they prefer, when multiple ids appear for the same device * NVIDIA SMI: Added memory free and per process memory usage charts to the collector * OpenLDAP: Added TLS support, to allow monitoring of LDAPS. * PHP-FPM: Add health check to raise alarms when the phpfm server is unreachable * PostgreSQL: Our configuration options to connect to a DB did not 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 netdata.conf. * Kubernetes Helm Chart improvements: + Added serviceName in statefulset spec to align with the k8s documentation + Added preStart command to persist slave machine GUIDs, so that pod deletion/addition during upgrades doesn't lose the slave history. + Disabled non-essential master netdata collector plugins to avoid duplicate data + 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 * python.d.plugin: Reduce memory usage with separate process for initial module checking and loaders cleanup * IPC shared memory charts * mysql module add ssl connection support * FreeIPMI: Have the debug option apply the internal freeipmi debug flags * Prometheus backend: Support legacy metric names for source=avg * Registry: Allow deleting the host we are looking at * SpigotMC: Use regexes for parsing.

We plan to provide a full set 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, check https://docs.netdata.cloud/web/api/health/#health-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 https://github.com/netdata/go-orchestrator#go-orchestrator-wip New data collectors: * Activemq (Go) * Consul (Go) * Lighttpd2 (Go) * Solr (Go) * Springboot2 (Go) * mdstat - nonredundant arrays (C) * CUPS printing system (C) High performance versions of older data collectors: * apache (Go) * dns_query (Go) * Freeradius (Go) * Httpcheck (Go) * Lighttpd (Go) * Portcheck (Go) * Nginx (Go) * cpufreq (C) * cpuidle (C) * mdstat (C) * power supply (C) Other improved data collectors: * Fix the python plugin clock (collectors falling behind). * adaptec_raid: add to python.d.conf. * apcupsd: Detect if UPS is online. * apps: Fix process statistics collection for FreeBSD. * apps: Properly lookup docker container name when running in ECS * fail2ban: Add 'Restore Ban' action. * go_expavar: Don't check for duplicate expvars. * hddtemp: Don't use disk model as dim name. * megacli: add to python.d.conf. * nvidia_smi: handle N/A values. * postgres: Fix integer out of range error on Postgres 11, fix locks count. * proc: Don't show zero charts for ZFS filesystem. * proc; Fix cached memory calculation. * sensors: Don't ignore 0 RPM fans on start. * smartd_log: check() unhandled exception: list index out of range. * SNMP: Gracefully ignore the offset if the value is not a number Health Monitoring: * Add Prowl notifications for iOS users. * Show count of active alarms per state in email notifications. * Show evaluated expression and expression variable values in email notifications. * Improve support for slack recipients (channels/users). * Custom notifications: Fix bug with alarm role recipients. Dashboards: * Server filtering in my-netdata menu when signed in to netdata.cloud * All units are now IEC-compliant abbreviations (KiB, MiB etc.). * GUI: Make entire row clickable in the registry menu showing the list of servers. Backends: * Do not report stale metrics to prometheus. Other: * Treat DT_UNKNOWN files as regular files. * API: Stricter rules for URL separators. - 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 a badge. * 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 time-frame. + 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). boo#1139094 * CVE-2018-18837 Fixed HTTP Header Injection (an attacker could send \n encoded in the request to inject an HTTP header into the response). boo#1139095 * 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 collection modules: * rethinkdbs for monitoring RethinkDB performance * proxysql for monitoring ProxySQL performance * litespeed for monitoring LiteSpeed web server performance. * uwsgi for monitoring uWSGI performance * unbound for monitoring the performance of Unbound DNS servers. * powerdns for monitoring the performance of PowerDNS servers. * dockerd for monitoring the health of dockerd * puppet for monitoring Puppet Server and Puppet DB. * logind for monitoring the number of active users. * adaptec_raid and megacli for monitoring the relevant raid controller * spigotmc for monitoring minecraft server statistics * boinc for monitoring Berkeley Open Infrastructure Network Computing clients. * w1sensor for monitoring multiple 1-Wire temperature sensors. * monit for collecting process, host, filesystem, etc checks from monit. * 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 client certificates. * 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 modules: * 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 collected. + histograms had wrong sampling rate calculations. + gauges now ignore sampling rate when no sign is included in the value. + 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 cores). + fixed /proc/net/snmp parsing of IcmpMsg lines that failed on a few systems. + Veritas Volume Manager disks are now recognized and named accordingly. + 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 ip.*. + 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 server). + fail2ban module now supports IPv6 too. + ceph module now checks permissions and properly reports issues + elasticsearch module got better error handling + nginx_plus module now uses upstream ip:port instead of transient id to identify dimensions. + redis, now it supports Pika, collects evited keys, fixes authentication issues reported and improves exception handling. + beanstalk, bug fix for yaml config loading. + mysql, the % of active connections is now monitored, query types are also charted. + varnish, now it supports versions above 5.0.0 + couchdb + phpfpm, now supports IPv6 too. + apache, now supports IPv6 too. + icecast + mongodb, added support for connect URIs + postgress + elasticsearch, now it supports versions above 6.3.0, fixed JSON parse errors + mdstat , now collects mismatch_cnt + openvpn_log * node.d.plugin NODE.JS modules + snmp was incorrectly parsing a new OID names as float. * charts.d.plugin BASH modules + nut now supports naming UPSes. Health monitoring: * Added variable $system.cpu.processors. * Added alarms for detecting abnormally high load average. * TCP SYN and TCP accept queue alarms, replacing the old softnet dropped alarm that was too generic and reported many false positives. * system alarms are now enabled on FreeBSD. * netdata now reads NIC speed and sets alarms on each interface to detect congestion. * Network alarms are now relaxed to avoid false positives. * New bcache alarms. * New mdstat alarms. * New apcupsd alarms. * New mysql alarms. * New notification methods: + rocket.chat + Microsoft Teams + syslog + fleep.io + 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 certain conditions. * Fixed a bug that caused slaves to consume 100% CPU (due to a misplaced lock) when multiple threads were adding dimensions on the same chart. * The receiving nodes of streaming (netdata masters and proxies) can now rate-limit the rate of inbound streaming requests received. * Re-worked time synchronization between netdata slaves and masters. API: * Badges that report time, now show "undefined" instead of "never".
