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

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/firehol/netdata/wiki/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/firehol/netdata/wiki/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/firehol/netdata/wiki/The-spectacles-of-a-web-server-log-file
* 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 CELCIUS
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/firehol/netdata/wiki/monitoring-IPMI

to avoid notification floods.
Alarms now support notification hysteresis (both static
and dynamic), notification self-cancellation, dynamic
thresholds based on current alarm status
* improved alarm notifications
netdata now supports:
- email notifications
- slack.com notifications on slack channels
- pushover.net notifications (mobile push notifications)
- telegram.org notifications
For all the above methods, netdata supports role-based
notifications, with multiple recipients for each role

dashboard is open in a browser window (no need to be
the active one).
All notifications are now clickable to get to the chart
that raised the alarm.
* improved IoT support!
netdata builds and runs with musl libc and runs on systems
based on busybox.
* improved containers support!
netdata runs on alpine linux (a low profile linux distribution
used in containers).

netdata (1.3.0) - 2016-08-28
At a glance:
- netdata has health monitoring / alarms!
- netdata has badges that can be embeded anywhere!
- netdata plugins are now written in Python!
- new plugins: redis, memcached, nginx_log, ipfs, apache_cache
IMPORTANT:
Since netdata now uses Python plugins, new packages are
required to be installed on a system to allow it work.
For more information, please check the installation page:
https://github.com/firehol/netdata/wiki/Installation
In detail:
* netdata has alarms!
Based on the POLL we made on github
(https://github.com/firehol/netdata/issues/436),
health monitoring was the winner. So here it is!
netdata now has a poweful health monitoring system embedded.
Please check the wiki page:
https://github.com/firehol/netdata/wiki/health-monitoring
* netdata has badges!
netdata can generate badges with live information from the
collected metrics.
Please check the wiki page:
https://github.com/firehol/netdata/wiki/Generating-Badges
* netdata plugins are now written in Python!
Thanks to the great work of Paweł Krupa (@paulfantom), most BASH
plugins have been ported to Python.
The new python.d.plugin supports both python2 and python3 and
data collection from multiple sources for all modules.
The following pre-existing modules have been ported to Python:
- apache
- cpufreq
- example
- exim
- hddtemp

- nginx
- phpfm
- postfix
- sensors
- squid
- tomcat
The following new modules have been added:
- apache_cache

when changing servers via the my-netdata menu.
The settings transferred are the dashboard theme, the online
help status and current pan and zoom timeframe of the dashboard.
* API improvements:
- reduction functions now support 'min', 'sum' and 'incremental-sum'.
- netdata now offers a multi-threaded and a single threaded
web server (single threaded is better for IoT).
* apps.plugin improvements:
- can now run with command line argument 'without-files'
to prevent it from enumating all the open files/sockets/pipes
of all running processes.
- apps.plugin now scales the collected values to match the
the total system usage.
- apps.plugin can now report guest CPU usage per process.
- repeating errors are now logged once per process.
* netdata now runs with IDLE process priority (lower than nice 19)
* netdata now instructs the kernel to kill it first when it starves
for memory.
* netdata listens for signals:
- SIGHUP to netdata instructs it to re-open its log files
(new logrotate files added too).
- SIGUSR1 to netdata saves the database
- SIGUSR2 to netdata reloads health / alarms configuration
* netdata can now bind to multiple IPs and ports.
* netdata now has new systemd service file (it starts as user
netdata and does not fork).
* Dozens of other improvements and bugfixes
netdata (1.2.0) - 2016-05-16
At a glance:
- netdata is now 30% faster
- netdata now has a registry (my-netdata dashboard menu)

contributed to the overal efficiency.
* netdata now has a CENTRAL REGISTRY !
The central registry tracks all your netdata servers
and bookmarks them for you at the 'my-netdata' menu
on all dashboards.
Every netdata can act as a registry, but there is also
a global registry provided for free for all netdata users!
* netdata now monitors CONTAINERS !
docker, lxc, or anything else. For each container it monitors
CPU, RAM, DISK I/O (network interfaces were already monitored)
* apps.plugin: now uses linux capabilities by default
without setuid to root
* netdata has now an improved signal handler
thanks to @simonnagl
* API: new improved CORS support
