netdata
New to netdata? Here is a live demo: http://my-netdata.io
[TOC] netdata is a system for distributed real-time performance and health monitoring. It provides unparalleled insights, in real-time, of everything happening on the system it runs (including applications such as web and database servers), using modern interactive web dashboards.
netdata is fast and efficient, designed to permanently run on all systems (physical & virtual servers, containers, IoT devices), without disrupting their core function.
netdata runs on Linux, FreeBSD, and MacOS.
Installation
Dependances
$ apt-get install zlib1g-dev uuid-dev libmnl-dev gcc make git autoconf autoconf-archive autogen automake pkg-config curl jq nodejs
install netdata!
Linux one liner
For all Linux systems, you can use this one liner to install the git version of netdata:
# basic netdata installation
$ bash <(curl -Ss https://my-netdata.io/kickstart.sh)
# install required packages for all netdata plugins
$ bash <(curl -Ss https://my-netdata.io/kickstart.sh) all
The above:
$ bash <(curl -Ss https://my-netdata.io/kickstart.sh) all --dont-wait --dont-start-it
x86_64 pre-built binary for any Linux
You can install a pre-compiled static binary of netdata for any Intel/AMD 64bit Linux system (even those that don't have a package manager, like CoreOS, CirrOS, busybox systems, etc). You can also use these packages on systems with broken or unsupported package managers.
To install the latest version use this:
$ bash <(curl -Ss https://my-netdata.io/kickstart-static64.sh)
For automated installs, append a space + --dont-wait to the command line. You can also append --dont-start-it to prevent the installer from starting netdata. Example:
$ bash <(curl -Ss https://my-netdata.io/kickstart-static64.sh) --dont-wait --dont-start-it
If your shell fails to handle the above one liner, do this:
# download the script with curl
$ curl https://my-netdata.io/kickstart-static64.sh >/tmp/kickstart-static64.sh
# or, download the script with wget
$ wget -O /tmp/kickstart-static64.sh https://my-netdata.io/kickstart-static64.sh
# run the downloaded script (any sh is fine, no need for bash)
$ sh /tmp/kickstart-static64.sh
The static builds install netdata at
/opt/netdata.
The static binary files are kept in this repo: https://github.com/firehol/binary-packages
Download any of the .run files, and run it. These files are self-extracting shell scripts built with makeself.
The target system does not need to have bash installed.
The same files can be used for updates too.
$ cd /opt
$ git clone https://github.com/firehol/netdata.git netdata --depth=1
$ cd netdata
$ ./netdata-installer.sh
Features
What does it monitor?
netdata collects several thousands of metrics per device. All these metrics are collected and visualized in real-time.
Almost all metrics are auto-detected, without any configuration.
This is a list of what it currently monitors:
-
CPU
usage, interrupts, softirqs, frequency, total and per core, CPU states -
Memory
RAM, swap and kernel memory usage, KSM (Kernel Samepage Merging), NUMA -
Disks
per disk: I/O, operations, backlog, utilization, space, software RAID (md)
-
Network interfaces
per interface: bandwidth, packets, errors, drops
-
IPv4 networking
bandwidth, packets, errors, fragments, tcp: connections, packets, errors, handshake, udp: packets, errors, broadcast: bandwidth, packets, multicast: bandwidth, packets -
IPv6 networking
bandwidth, packets, errors, fragments, ECT, udp: packets, errors, udplite: packets, errors, broadcast: bandwidth, multicast: bandwidth, packets, icmp: messages, errors, echos, router, neighbor, MLDv2, group membership, break down by type -
Linux DDoS protection
SYNPROXY metrics -
fping latencies
for any number of hosts, showing latency, packets and packet loss
-
Processes
running, blocked, forks, active -
Entropy
random numbers pool, using in cryptography
- Applications
by grouping the process tree and reporting CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets - per group
-
Users and User Groups resource usage
by summarizing the process tree per user and group, reporting: CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets -
Apache and lighttpd web servers
mod-status(v2.2, v2.4) and cache log statistics, for multiple servers -
ceph
OSD usage, Pool usage, number of objects, etc.
And you can extend it, by writing plugins that collect data from any source, using any computer language.
