如何在AWS中分配动态资产ID站点监视仪表板定义云形式？

Question

我们创建了一个云形式模板，用于自动实现AWS站点监视仪表板。我们想在下面的仪表板定义中动态地引用并分配资产逻辑ID。

{\"widgets\":[{\"type\":\"sc-line-chart\",\"title\":\"power_all_plants_5m\",\"x\":0,\"y\":0,\"height\":3,\"width\":3,\"metrics\":[{\"type\":\"iotsitewise\",\"label\":\"power_all_plants_5m (All Power Plants)\",\"assetId\":\"0cd25cb9-89f9-4a93-b2bf-88050436f700\",\"propertyId\":\"fd34bba7-4ea2-4d62-9058-ab78b726b61a\",\"dataType\":\"DOUBLE\"}],\"alarms\":[],\"properties\":{\"colorDataAcrossThresholds\":true},\"annotations\":{\"y\":[]}},{\"type\":\"sc-line-chart\",\"title\":\"Generator-1\",\"x\":3,\"y\":0,\"height\":3,\"width\":3,\"metrics\":[{\"type\":\"iotsitewise\",\"label\":\"sum_watts_5m (Generator-1)\",\"assetId\":\"45b97aaa-3f0c-4312-a8a5-a00e4da8ec37\",\"propertyId\":\"e22d9a23-4ac8-432a-816b-cc4a2138b287\",\"dataType\":\"DOUBLE\"},{\"type\":\"iotsitewise\",\"label\":\"rpm (Generator-1)\",\"assetId\":\"45b97aaa-3f0c-4312-a8a5-a00e4da8ec37\",\"propertyId\":\"c6a40902-f07b-40ba-b6c5-3509b069dd4c\",\"dataType\":\"DOUBLE\"}],\"alarms\":[],\"properties\":{\"colorDataAcrossThresholds\":true},\"annotations\":{\"y\":[]}},{\"type\":\"sc-line-chart\",\"title\":\"Generator-2\",\"x\":0,\"y\":3,\"height\":3,\"width\":3,\"metrics\":[{\"type\":\"iotsitewise\",\"label\":\"sum_watts_5m (Generator-2)\",\"assetId\":\"b999319c-20ec-4060-b3b7-bc5ce7ef189c\",\"propertyId\":\"e22d9a23-4ac8-432a-816b-cc4a2138b287\",\"dataType\":\"DOUBLE\"},{\"type\":\"iotsitewise\",\"label\":\"rpm (Generator-2)\",\"assetId\":\"b999319c-20ec-4060-b3b7-bc5ce7ef189c\",\"propertyId\":\"c6a40902-f07b-40ba-b6c5-3509b069dd4c\",\"dataType\":\"DOUBLE\"}],\"alarms\":[],\"properties\":{\"colorDataAcrossThresholds\":true},\"annotations\":{\"y\":[]}}]}

通过添加向后斜线（）以及双引号，将此JSON的字面形式转换为YAML，因为我们将YAML用作CloudFormation模板的默认语言，否则看起来如下。

我们想使用预先创建的资产动态分配资产ID。我们尝试了以下变化，但没有命运。

现有值 - ＆gt; 0CD25CB9-89F9-4A93-B2BF-88050436F700

尝试以下更改： -

[{\"Ref\":\"GeneratorAsset\"}]
!Ref GeneratorAsset
\"!Ref GeneratorAsset\"
{\"Ref\":GeneratorAsset}
{\"Ref\":\"GeneratorAsset\"}
\"{\"Ref\":\"GeneratorAsset\"}\"
\"{\"Fn::Sub\":${GeneratorAsset}}\"
\"{\"Fn::Sub\":${!GeneratorAsset}}\"
\"{\"Fn::Sub\":${!GeneratorAsset} }\"

此处GeneratorAsaters是在仪表板之前已经创建的资源。请求任何云形式专家，以帮助我们用正确的动态字符串替换ID值。
