説明
これらのパラメーターと、各ダッシュボードウィジェットフィールドオブジェクトの有効なプロパティ値を使用することで、dashboard.createメソッドおよびdashboard.updateメソッドでアイテムの値ウィジェットを設定できます。
ウィジェットのfieldsプロパティは、ダッシュボードの作成または更新時に検証されません。 これにより、ユーザーは組み込みウィジェットを変更したり、カスタムウィジェットを作成したりできますが、ウィジェットを誤って作成または更新してしまうリスクも生じます。 アイテムの値ウィジェットを正常に作成または更新するには、以下の表に記載されているパラメーターの動作を参照してください。
Parameters
The following parameters are supported for the Item value widget.
| Parameter | type | name | value | |
|---|---|---|---|---|
| Refresh interval | 0 | rf_rate | 0 - No refresh; 10 - 10 seconds; 30 - 30 seconds; 60 - (default) 1 minute; 120 - 2 minutes; 600 - 10 minutes; 900 - 15 minutes. |

| Item | 4 | itemid.0 | Item ID. Parameter behavior: - required if Item (Widget) is not set |
|
| Item (Widget) | 1 | itemid._reference | Instead of Item ID:ABCDE._itemid - set a compatible widget (with its Reference parameter set to "ABCDE") as the data source for items.Parameter behavior: - required if Item is not set |
|
| Show | 0 | show.0 | 1 - Description; 2 - Value; 3 - Time; 4 - Change indicator; 5 - Sparkline. Default: 1, 2, 3, 4. Note: To configure multiple values, create a dashboard widget field object for each value with an incremented number in the property name. |

Advanced configuration
The following advanced configuration parameters are supported for the Item value widget.
The number in the Thresholds property name (e.g. thresholds.0.color) references the threshold place in a list, sorted in ascending order. However, if thresholds are configured in a different order, the values will be sorted in ascending order after updating widget configuration in Zabbix frontend (e.g. "thresholds.0.threshold":"5" → "thresholds.0.threshold":"1"; "thresholds.1.threshold":"1" → "thresholds.1.threshold": "5").

例
次の例は、アイテムの値ウィジェットのダッシュボードウィジェットフィールドオブジェクトの設定を説明することだけを目的としています。 ダッシュボードの設定の詳細については、dashboard.createを参照してください。
アイテムの値ウィジェットの設定
アイテム"42266"(Zabbixエージェントの可用性)のアイテム値を表示するアイテムの値ウィジェットを設定します。さらにウィジェットを複数の詳細オプションを使用して、Zabbixエージェントの可用性ステータスに基づいて変更される動的な背景色といった視覚的な調整をします。
