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 = *
Chartlab Example

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

Chartlab Example

Wildcard series are supported in all widgets including bar widgets.

Bar Chart Wildcards

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