Overrides

Use overrides to apply additional rendering options for metrics, including custom thresholds and clickthroughs.

This is an example override that sets the unit for metrics that match a regular expression:

Below is the same override with thresholds added:

The final result of the above override with thresholds applied:

Override settings

Label: Label overrides to ease search. The label is not rendered on the polygon.
Metric: If set, the panel will provide "hints" for metric names, and allow you to enter a regular expression to match multiple metrics.
Decimals: Sets the maximum number of decimals to be displayed. Leave this empty to show all decimals.
Statistic to Display (Stat): Allows you to specify a different statistic to use for the matching metric, and will replace the global statistic. As with the global setting, the full set of statistics Grafana provides are available.
Unit Formatting: All of the unit types are available in this selector and will be applied to the value displayed. A suffix is typically added by the formatter to indicate the unit like "B/sec" or symbols for temperatures, percentages, and similar.
Thresholds: An override can specify a set of thresholds that are to be applied to the matching metric, and will replace any global threshold settings. See Use thresholds for details on how thresholds are evaluated.
Prefix: Text in this field will be prepended to the rendered metric.
Suffix: Text in this field will be appended to the rendered metric after any unit text is applied.
Clickthrough URL: Use this setting to indicate the URL to open when clicking the polygon. See more at Use Clickthroughs.

See the menu at the bottom right side of the override for additional controls.

Ordering: Allows you to move the override so you can force a different evaluation priority or simply to group similar overrides together.
Hide/Show: Use the "eye" icon to enable/disable the override.
Duplicate: Allows you to make a copy of the current override and append it to the end of the list, named with "Copy" at the end.
Delete: This button will delete the override completely.
