The actual scene
The company's products to be seen whether Ubuntu host capability to measure customer site products to meet the needs of high-frequency use
Selection
After comparing a lot of tools, consider the time factor cost, with a relatively simple Munin
installation steps
1. apt-get install munin
2. Place the following statement in front of the # removed
// generates a file storage path
dbdir / var / lib / munin htmldir / var / cache / munin / www started at / var / log / angina rundir / var / RUN / the munin
// the HTML template path
tmpldir / etc / the munin / Templates
// hostname modify (if necessary), the position following the following line
# a simple host tree
3. Configure the web server to allow access munin page, such as Nginx

Many indicators can be seen daily, weekly, monthly and yearly statistics view, very convenient
Extension: server performance monitoring of key indicators
- CPU: idle index, the higher the free end of the load
- Memory : See unused size, the greater the smaller the unused server load
- Disk: IO Wait Time greater, the larger the disk. IOwait divided into Read IO Wait Time and Write IO Wait TIme
- Network: the network and look into the average bandwidth and server bandwidth to do with the percentage (this is Ali cloud and Huawei cloud clearer)
Extension: Other common tools
- Zabbix: the most widely used enterprise applications
- Nagios: Open Source powerful graphical tools
- open-falcon: millet open source monitoring system , more suitable for domestic use habits programmer
- MRTG: graphical interface tool
The first three are open source monitoring tools are often used to compare, contrast can refer to the following ( evaluation on this network, just a reference tool only to achieve maximum value at the appropriate scene )

Extension: Under Linux common supervisory command
- top: a powerful real-time performance monitoring command, is strongly recommended
- free: Checking the Memory Usage
- df: View disk space
- netstat: View network case
