# Templates and variables
|
|
|
|
|
|
|
|
|
|
A variable is a placeholder for a value. You can use variables in metric queries and in panel titles. So when you change
|
|
|
|
|
the value, using the dropdown at the top of the dashboard, your panel's metric queries will change to reflect the new value.
|
|
|
|
|
|
|
|
|
|
Variables allow you to create more interactive and dynamic dashboards. Instead of hard-coding things like server, application,
|
|
|
|
|
and sensor names in your metric queries, you can use variables in their place. Variables are displayed as dropdown lists at the top of
|
|
|
|
|
the dashboard. These dropdowns make it easy to change the data being displayed in your dashboard.
