netdata (1.10.0) - 2018-03-27

Please check full changelog at github. https://github.com/netdata/netdata/releases

netdata (1.9.0) - 2017-12-17

Please check full changelog at github. https://github.com/netdata/netdata/releases

netdata (1.8.0) - 2017-09-17

This is mainly a bugfix release. Please check full changelog at github.

netdata (1.7.0) - 2017-07-16

  • netdata is still spreading fast

    we are at 320.000 users and 132.000 servers

    Almost 100k new users, 52k new installations and 800k docker pulls since the previous release, 4 and a half months ago.

    netdata user base grows at about 1000 new users and 600 new servers per day. Thank you. You are awesome.

  • The next release (v1.8) will be focused on providing a global health monitoring service, for all netdata users, for free.

  • netdata is now a (very fast) fully featured statsd server and the only one with automatic visualization: push a statsd metric and hit F5 on the netdata dashboard: your metric visualized. It also supports synthetic charts, defined by you, so that you can correlate and visualize your application the way you like it.

  • netdata got new installation options It is now easier than ever to install netdata - we also distribute a statically linked netdata x86_64 binary, including key dependencies (like bash, curl, etc) that can run everywhere a Linux kernel runs (CoreOS, CirrOS, etc).

  • metrics streaming and replication has been improved significantly. All known issues have been solved and key enhancements have been added. Headless collectors and proxies can now send metrics to backends when data source = as collected.

  • backends have got quite a few enhancements, including host tags and metrics filtering at the netdata side; prometheus support has been re-written to utilize more prometheus features and provide more flexibility and integration options.

  • netdata now monitors ZFS (on Linux and FreeBSD), ElasticSearch, RabbitMQ, Go applications (via expvar), ipfw (on FreeBSD 11), samba, squid logs (with web_log plugin).

  • netdata dashboard loading times have been improved significantly (hit F5 a few times on a netdata dashboard - it is now amazingly fast), to support dashboards with thousands of charts.

  • netdata alarms now support custom hooks, so you can run whatever you like in parallel with netdata alarms.

  • As usual, this release brings dozens of more improvements, enhancements and compatibility fixes.

netdata (1.6.0) - 2017-03-20

  • birthday release: 1 year netdata

    netdata was first published on March 30th, 2016. It has been a crazy year since then:

    225.000 unique netdata users

          currently, at 1.000 new unique users per day

    80.000 unique netdata installations

          currently, at 500 new installation per day

    610.000 docker pulls on docker hub

    4.000.000 netdata sessions served

          currently, at 15.000 sessions served per day

    20.000 github stars

          Thank you!
   You are awesome!

  • central netdata is here

    This is the first release that supports real-time streaming of metrics between netdata servers.

    netdata can now be:

    • autonomous host monitoring (like it always has been)

    • headless data collector (collect and stream metrics in real-time to another netdata)

    • headless proxy (collect metrics from multiple netdata and stream them to another netdata)

    • store and forward proxy (like headless proxy, but with a local database)

    • central database (metrics from multiple hosts are aggregated)

    metrics databases can be configured on all nodes and each node maintaining a database may have a different retention policy and possibly run (even different) alarms on them.

  • monitoring ephemeral nodes

    netdata now supports monitoring autoscaled ephemeral nodes, that are started and stopped on demand (their IP is not known).

    When the ephemeral nodes start streaming metrics to the central netdata, the central netdata will show register them at "my-netdata" menu on the dashboard.

    For more information check: https://github.com/netdata/netdata/tree/master/streaming#monitoring-ephemeral-nodes

  • monitoring ephemeral containers and VM guests

    netdata now cleans up container, guest VM, network interfaces and mounted disk metrics, disabling automatically their alarms too.

    For more information check: https://github.com/netdata/netdata/tree/master/collectors/cgroups.plugin#monitoring-ephemeral-containers

  • apps.plugin ported for FreeBSD

    @vlvkobal has ported "apps.plugin" to FreeBSD. netdata can now provide "Applications", "Users" and "User Groups" on FreeBSD.

  • web_log plugin

    @l2isbad has done a wonderful job creating a unified web log parsing plugin for all kinds of web server logs. With it, netdata provides real-time performance information and health monitoring alarms for web applications and web sites!

    For more information check: https://github.com/netdata/netdata/blob/master/collectors/python.d.plugin/web_log#web_log

  • backends

    netdata can now archive metrics to JSON backends (both push, by @lfdominguez, and pull modes).

  • IPMI monitoring

    netdata now has an IPMI plugin (based on freeipmi) for monitoring server hardware.

    The plugin creates (up to) 8 charts:

    1. number of sensors by state
    2. number of events in SEL
    3. Temperatures CELSIUS
    4. Temperatures FAHRENHEIT
    5. Voltages
    6. Currents
    7. Power
    8. Fans

    It also supports alarms (including the number of sensors in critical state).

    For more information, check: https://github.com/netdata/netdata/tree/master/collectors/freeipmi.plugin
