3 **Real-time performance monitoring, done right!**

9 **netdata** is a highly optimized Linux daemon providing **real-time performance monitoring for Linux systems, Applications, SNMP devices, over the web**!
11 It tries to visualize the **truth of now**, in its **greatest detail**, so that you can get insights of what is happening now and what just happened, on your systems and applications.
15 1. **Beautiful out of the box** with bootstrap dashboards
16 2. You can build your **custom dashboards**, with simple HTML (no javascript necessary)
17 3. **Blazingly fast** and **super efficient**, just 2% of a single core and a few MB of RAM
18 3. **Zero configuration** - you just install it and it autodetects everything
19 4. **Zero dependencies**, it is its own web server for its static web files and its web API
20 4. **Extensible**, you can monitor anything you can get a metric for, using its Plugin API (anything can be a netdata plugin - from BASH to node.js)
21 7. **Embeddable**, it can run anywhere a Linux kernel runs
23 This is what it currently monitors (most with zero configuration):
25 1. **CPU usage, interrupts, softirqs and frequency** (total and per core)
26 2. **RAM, swap and kernel memory usage** (including KSM and kernel memory deduper)
27 3. **Disk I/O** (per disk: bandwidth, operations, backlog, utilization, etc)
28 4. **Network interfaces** (per interface: bandwidth, packets, errors, drops, etc)
29 5. **IPv4 networking** (packets, errors, fragments, tcp: connections, packets, errors, handshake, udp: packets, errors, broadcast: bandwidth, packets, multicast: bandwidth, packets)
30 6. **netfilter / iptables** Linux firewall (connections, connection tracker events, errors, etc)
31 7. **Processes** (running, blocked, forks, active, etc)
33 9. **NFS file servers**, v2, v3, v4 (I/O, cache, read ahead, RPC calls)
34 10. **Network QoS** (yes, the only tool that visualizes network `tc` classes in realtime)
35 11. **Applications**, by grouping the process tree (CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets, etc)
36 12. **Apache web server** mod-status (v2.2, v2.4)
37 13. **Nginx web server** stub-status
38 14. **mySQL databases** (more than one DBs, each showing: bandwidth, queries/s, handlers, locks, issues, tmp operations, connections, binlog metrics, threads, innodb metrics, etc)
39 15. **ISC Bind / Named** (clients, requests, queries, updates, failures and several per view metrics)
40 16. **Postfix** message queue (entries, size)
41 17. **Squid proxy** (clients bandwidth and requests, servers bandwidth and requests)
42 18. **Hardware sensors** (temperature, voltage, fans, power, humidity, etc)
43 19. **NUT UPSes** (load, charge, battery voltage, temperature, utility metrics, output metrics)
45 You can also monitor any number of **SNMP devices**, although you will need to configure these.
