> *New to netdata? Here is a live demo: [http://my-netdata.io](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
|
|
|
|
```bash
|
|
$ 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:
|
|
|
|
```sh
|
|
# 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:
|
|
|
|
```sh
|
|
$ 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:
|
|
|
|
```sh
|
|
$ 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:
|
|
|
|
```sh
|
|
$ 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:
|
|
|
|
```sh
|
|
# 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](https://github.com/megastep/makeself).
|
|
|
|
The target system does **not** need to have bash installed.
|
|
|
|
The same files can be used for updates too.
|
|
|
|
```bash
|
|
$ cd /opt
|
|
$ git clone https://github.com/firehol/netdata.git netdata --depth=1
|
|
$ cd netdata
|
|
$ ./netdata-installer.sh
|
|
```
|
|
|

## 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**<br/>
|
|
usage, interrupts, softirqs, frequency, total and per core, CPU states
|
|
|
|
- **Memory**<br/>
|
|
RAM, swap and kernel memory usage, KSM (Kernel Samepage Merging), NUMA
|
|
|
|
- **Disks**<br/>
|
|
per disk: I/O, operations, backlog, utilization, space, software RAID (md)
|
|
|
|
|
|
|
|
- **Network interfaces**<br/>
|
|
per interface: bandwidth, packets, errors, drops
|
|
|
|
|
|
|
|
- **IPv4 networking**<br/>
|
|
bandwidth, packets, errors, fragments,
|
|
tcp: connections, packets, errors, handshake,
|
|
udp: packets, errors,
|
|
broadcast: bandwidth, packets,
|
|
multicast: bandwidth, packets
|
|
|
|
- **IPv6 networking**<br/>
|
|
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**<br/>
|
|
SYNPROXY metrics
|
|
|
|
- **fping** latencies</br>
|
|
for any number of hosts, showing latency, packets and packet loss
|
|
|
|
|
|
|
|
- **Processes**<br/>
|
|
running, blocked, forks, active
|
|
|
|
- **Entropy**<br/>
|
|

|
|
|
|
|
|
|
|
|
|
|
|
- **Applications**<br/>
|
|
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**<br/>
|
|
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**<br/>
|
|
`mod-status` (v2.2, v2.4) and cache log statistics, for multiple servers
|
|
|
|
- **statsd**<br/>
|
|
[netdata is a fully featured statsd server](https://github.com/firehol/netdata/wiki/statsd)
|
|
|
|
- **ceph**<br/>
|
|

And you can extend it, by writing plugins that collect data from any source, using any computer language.
