1. Dashboard'a birden fazla satır eklenebilir.

2. Her satırda bir veya daha fazla panel bulunur. 

Paneller için açıklama şöyle

The panel is the basic visualization building block in Grafana. Each panel has a query editor specific to the data source selected in the panel. The query editor allows you to extract the perfect visualization to display on the panel. With the exception of a few special use panels, a panel is a visual representation of one or more queries. The queries display data over time. This can range from temperature fluctuations to current server status to a list of logs or alerts. In order to display data, needs to have at least one data source added to Grafana.

There are a wide variety of styling and formatting options for each panel. Panels can be dragged and dropped and rearranged on the dashboard. They can also be resized.

Drag and drop panels by clicking and holding the panel title, then dragging it to its new location. it can also easily resize panels by clicking the (-) and (+) icons.

Templates and variables

Açıklaması şöyle

A template is any query that contains a variable.

For example : 

wmi_system_threads{instance=~"$server"}

Variable syntax

Açıklaması şöyle

Panel titles and metric queries can refer to variables using two different syntaxes:

- $varname This syntax is easy to read, but it does not allow users to use a variable in the middle of a word. Example: apps.frontend.$server.requests.count

- ${var_name} Use this syntax when the user wants to interpolate a variable in the middle of an expression.

- ${var_name:<format>} This format gives users more control over how Grafana interpolates values.

- [[varname]] Do not use it. Deprecated old syntax, will be removed in a future release.

Before queries are sent to the data source the query is interpolated, meaning the variable is replaced with its current value. During interpolation, the variable value might be escaped in order to conform to the syntax of the query language and where it is used. For example, a variable used in a regex expression in an InfluxDB or Prometheus query will be regex escaped. Read the data source specific documentation topic for details on value escaping during interpolation.

Variable values are always synced to the URL using the syntax var-<varname>=value.

Variable best practices

- Variable drop-down lists are displayed in the order they are listed in the variable list in Dashboard settings.

-  Put the variables that you will change often at the top, so they will be shown first (far left on the dashboard).

Örnek

Şöyle yaparız. Burada $__timeFilter bir değişken. Grafana dashboard ile seçili zaman aralığını temsil ediyor.

SELECT 
  UNIX_TIMESTAMP(date_format(created_date,'%Y-%m-%d %H:%i')) as time_sec,
  count(*) as value,
  variable_name as metric
FROM dashboard.service_response_time
  WHERE $__timeFilter(created_date)
  GROUP BY time_sec,variable_name
  ORDER BY time_sec ASC;
