Wildcards

Wildcards in tag values can used be to retrieve multiple series from the server instead of defining separate series for each tag in the widget configuration.

The * wildcard can be specified both in tag value as well as in entity name.

[series]
    entity = nurswgvml007
    metric = disk_used_percent
    [tags]
      mount_point = *

The wildcard series can be referenced by derived series using aliases.

Wildcard series are supported in all widgets including bar widgets.

The bar widget provides a multiple-column setting which places derived series with the same entity and tags into separate columns.
