Graphical monitoring grafana Build

Tips ： The following is the main body of this article , The following cases can be used for reference

One 、grafana Introduction to

grafana It's one that uses go Open source applications written in language , It is mainly used for visualization of large scale index data , It is the most popular time series data display tool in network architecture and application analysis , At present, it has supported most of the commonly used time series databases . The best reference is the official website （http://docs.grafana.org/）
Grafana Supports many different data sources . Each data source has a specific query editor , The editor's custom features and functions are open to specific data sources . The following data sources are officially supported :Graphite,Elasticsearch,InfluxDB,Prometheus,Cloudwatch,MySQL and OpenTSDB etc.
DashBoard： The dashboard , It's like a car dashboard that shows a lot of information , Including speed , Water tank temperature, etc .Grafana Of DashBoard It's to show in various graphic ways from Datasource The data we got .
Row： That's ok ,DashBoard The basic unit of composition , One DashBoard It can contain many row. One row It can show one kind of information or a combination of many kinds of information , For example, the system memory utilization rate ,CPU Five minute and ten minute average load, etc . So in a DashBoard A lot of content can be displayed on the Internet .
Panel： panel , It's actually row The way information is presented , Support forms （table）, list （alert list）, Thermogram （Heatmap） And so on , You can go to the official website for details .
Query Editor： Query editor , It is used to specify which part of the data to get . Be similar to sql Query statement , For example, you're going to be in a row It shows test The data in this table , that Query Editor It can be written as select *from test. It's just an analogy , Actually every DataSource The way to get data is different , So it's written differently （http://docs.grafana.org/features/datasources/）, Such as zabbix, Data is obtained by specifying a monitoring item .
Organization： organization ,org It's a big concept , Each user can have multiple org,grafana There is a default main org. Users can log in at different org Switch between , The premise is that the user has multiple org. Different org It's totally different , Include datasource,dashboard It's not the same . Create a org It's like opening a whole new view , be-all datasource,dashboard We have to start again .
User： user , The concept should be simple , Needless to say .Grafana There are three roles for users admin,editor,viewer.admin The highest authority , You can do anything , Include creating users , newly added Datasource, establish DashBoard.editor Roles cannot create users , You can't add Datasource, You can create DashBoard.viewer Characters can only be viewed DashBoard. stay 2.1 A new role has been added to the version and beyond read only editor（ Read only edit mode ）, This mode allows users to modify DashBoard, But it's not allowed to keep . Every user You can have multiple organization.
