-**Real-time performance monitoring, done right!**
+**Real-time performance and health monitoring, done right!**
This is the default dashboard of **netdata**:
- real-time, per second updates, snappy refreshes!
- 300+ charts out of the box, 2000+ metrics monitored!
- zero configuration, zero maintenance, zero dependencies!
+ - dozens of health monitoring alarms, out of the box!
Live demo: [http://my-netdata.io](http://my-netdata.io)
This is what you get:
-- **Stunning bootstrap dashboards**, out of the box (themable: dark, light)
+- **Stunning bootstrap dashboards**, out of the box (theme-able: dark, light)
- **Blazingly fast** and **super efficient**, mostly written in C (for default installations, expect just 2% of a single core CPU usage and a few MB of RAM)
-- **Zero configuration** - you just install it and it autodetects everything
+- **Zero configuration** - you just install it and it auto-detects everything
- **Zero dependencies**, it is its own web server for its static web files and its web API
- **Zero maintenance**, you just run it, it does the rest
- **Custom dashboards** that can be built using simple HTML (no javascript necessary)
-- **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, so you can easily monitor any application, any API)
+- **Extensible**, you can monitor anything you can get a metric for, using its Plugin API (anything can be a netdata plugin - from BASH to python and node.js, so you can easily monitor any application, any API)
- **Embeddable**, it can run anywhere a Linux kernel runs (even IoT) and its charts can be embedded on your web pages too
---
- **Entropy** (random numbers pool, using in cryptography)
-- **NFS file servers**, v2, v3, v4 (I/O, cache, read ahead, RPC calls)
+- **NFS file servers and clients**, v2, v3, v4 (I/O, cache, read ahead, RPC calls)
- **Network QoS** (yes, the only tool that visualizes network `tc` classes in realtime)
- **Users and User Groups resource usage**, by summarizing the process tree per user and group (CPU, memory, disk reads, disk writes, swap, threads, pipes, sockets, etc)
-- **Apache web server** mod-status (v2.2, v2.4) and cache log statistics (multiple servers)
+- **Apache web servers** mod-status (v2.2, v2.4) and cache log statistics (multiple servers - compatible with lighttpd too)
-- **Nginx web server** stub-status (multiple servers)
+- **Nginx web servers** stub-status (multiple servers)
- **mySQL databases** (multiple servers, each showing: bandwidth, queries/s, handlers, locks, issues, tmp operations, connections, binlog metrics, threads, innodb metrics, etc)
- **memcached databases** (multiple servers, each showing: bandwidth, connections, items, etc)
-- **ISC Bind name server** (multiple servers, each showing: clients, requests, queries, updates, failures and several per view metrics)
