Because Nagios is too complex, the previous Zabbix has emerged as a condition of knowledge. I just want to find a tool that can collect data for analysis in real time, glances is undoubtedly the best choice.In addition, when I was looking for tools, I found a relatively good simple monitoring tool--linux dashboard. On GitHub, you can go to research.Glances installation is very simple, not only support the display of data directly on the terminal, but also support the display on the web, in addit
. Combined with the above mentioned single-machine storage content, you can do a quick query. Further, we consider the time range of timing data is very long, we need to be divided into several segments according to the time range, respectively, stored on different machines, so for the large-scale series of data can support concurrent queries, optimize query speed. For example, the first row and the third row are the same tag (sensor=95d8-7913;city= Shanghai), so the same shard is assigned, and

(11,0,7,0), these values can be expressed in 4bit. That is to say [23,5,4,0xb0700000] (23,22,24,25,24). 4 of them represent a total of 4 in the following. If such a rule has been maintained to 100 int value, it can be represented by 16 int, with a compression rate of up to 6.3.The specifics are a lot more complicated, but here's a simple example. The InfluxDB lossless compression algorithm has a complete description on its page (note 3), which can be
States is a configuration language in Saltstack and requires a large number of states files to be written in daily configuration management. For example, install a package, then manage a configuration file, and finally ensure that a service runs correctly.Write some states SLS files (files describing the state configuration) to describe and implement our functionality. The states SLS file is written in Yaml syntax. Of course states SLS files also support the use of the Python language, in fact,
