For example, if you're monitoring the CPU usage of a server, you can use a state timeline to visualize the different states, such as “LOW,” “NORMAL,” “HIGH,” or “CRITICAL,” over time. Each state is represented by a different color and the lengths represent the duration of time that the server remained in that state:

- **Timestamps** - Indicate when each state change occurred. This could also be the start time for the state change. You can also add an optional timestamp to indicate the end time for the state change.
- **Entity name/identifier** - Represents the name of the entity you're trying to monitor.

If your query results aren't in a table format like the preceding examples, especially for time-series data, you can apply specific [transformations](https://stackoverflow.com/questions/68887416/grafana-state-timeline-panel-with-values-states-supplied-by-label) to achieve this.
