- improved IoT and containers support!
- alarms improved in almost every way!
- new plugins:
softnet netdev,
extended TCP metrics,
UDPLite

In detail:
* improved alarms
Many new alarms have been added to detect common kernel
configuration errors and old alarms have been re-worked
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
and severity filtering per recipient!
Also, netdata support HTML5 notifications, while the
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).
* Dozens of other improvements and bugfixes
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
- mysql
- nginx
- phpfm
- postfix
- sensors
- squid
- tomcat
The following new modules have been added:
- apache_cache
- dovecot
- ipfs
- memcached
- nginx_log
- redis
* other data collectors:
- Thanks to @simonnagl netdata now reports disk space usage.
* dashboards now transfer a certain settings from server to server
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)
- netdata now monitors Linux Containers (docker, lxc, etc)
IMPORTANT:
This version requires libuuid. The package you need is:
- uuid-dev (debian/ubuntu), or
- libuuid-devel (centos/fedora/redhat)
In detail:
* netdata is now 30% faster !
- Patches submitted by @fredericopissarra improved overall
netdata performance by 10%.
- A new improved search function in the internal indexes
made all searches faster by 50%, resulting in about
20% better performance for the core of netdata.
- More efficient threads locking in key components
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
* SNMP: counter64 support fixed
* MYSQL: more charts, about QCache, MyISAM key cache,
InnoDB buffer pools, open files
* DISK charts now show mount point when available
* Dashboard: improved support for older web browsers
and mobile web browsers (thanks to @simonnagl)
* Multi-server dashboards now allow de-coupled refreshes for
each chart, so that if one netdata has a network latency
the other charts are not affected
* Several other minor improvements and bugfixes
