Netdata Real-time performance monitoring tool for Linux

Guide

This article will introduce a very useful tool--netdata, which is a real-time Linux performance monitoring tool, for an open source tool, I have a translation of its English documents, the level of limited, there are translation errors in the place to welcome everyone to point out, I hope this article to help you, thank you.

Netdata

Real-time performance monitoring (looks like it's very high)

Features:

Netdata is a highly optimized Linux daemon that provides real-time performance monitoring for Linux systems, applications, SNMP services, and more. It is visualized by means of which the most subtle details of the monitored person are revealed. In this way, you can clearly understand the state of your system and your application at this time. Using this software, you can get:

1. Graceful interface: Control interface under Bootstrap frame 2. Custom Control Interface: You can use simple HTML code to customize the control interface (no JavaScript required) 3. Extremely fast and efficient: programs are written using C (default installation, Expect only 2% of single-core CPU usage and a little memory usage) 4.0 Configuration: You just have to install it, and then it automatically monitors all data 5.0 dependencies: its static network files and network interfaces have its own network server 6. Extensible: Use its own plug-in API ( There are many ways to make its plugins, from bash to node. js, and you can detect any measurable data. 7. embeddable: It can run anywhere the Linux kernel can run

Monitoring content:

This is what it detects at the moment (most do not need to be configured to start monitoring after installation)

1.CPU usage, interrupts, soft interrupts and frequencies (total and per single core) 2.RAM, swap and utilization of kernel memory (including KSM and kernel memory Deduper) 3. Hard drive input/output (bandwidth, operation, sorting, utilization, etc.) for each hard drive

4.ipv4 Network (packet, error, shard): TCP: Connection, packet, error, handshake UDP: Packet, error broadcast: bandwidth, packet multicast: bandwidth, packet 5. Netfilter/iptables Linux Firewall (connection, connection tracking events, errors, etc.) 6. Process (running, blocked, forked, active, etc.) 7. Operating Efficiency 8. NFS File server, V2,V3,V4 (input/output, cache, pre-read, RPC call) 9. Network Service Quality (the only tool that can visualize network status in real time)

11. Application, by grouping the process tree (CPU, memory, hard disk read, hard disk write, swap, thread, pipe, socket, etc.)

12.Apache Web Server status (v2.2, v2.4) 13.Nginx Web Server Status 14.Mysql database (multiple servers, single display: bandwidth, query/s, processor, lock, problem, temporary operation, connection, binary log, thread, InnoDB engine, etc.) 15. ISC bind domain Name server (multiple servers, single display: Customer, request, query, update, failure, etc.) 16. Postfix mail Server Message Queue (entry, size) 17. Squid Proxy Server (customer bandwidth and requests, service bandwidth and requests) 18. Hardware sensor (temperature, voltage, fan, power supply, humidity, etc.) 19.NUT upses (load, charge, battery voltage, temperature, usage indicator, Output indicator)

You can monitor any number of SNMP services, but you'll need to configure the software to extend it, and you can write plugins in any language to collect data from any source
