Asset Diff API

Asset Diff API

GET http://{kubecost-addresss}/model/assets/diff

The Asset Diff API provides a diff of two windows that returns all the added, removed, or cost changed assets from the later window (before parameter) to the earlier window (after parameter). This endpoint does a comparison of two asset sets in the given windows and accumulates the results.

Path Parameters

Name	Type	Description
before*	String	Duration in time of the past. Supports hours or days before the current time in the following format: 2h or 3d. before must be further in the past than after (e.g. after=1d, before=1d offset 1d)
after*	String	Duration in time closest to now. Supports hours or days before the current time in the following format: 2h or 3d. after must be closer to now than before (e.g. before=1d offset 7d, after=1d offset 3d)
costChangeRatio	float64	Changes the ratio of cost changes when displaying 'Changed' types. e.g. costChangeRatio=0.1 will display all assets that had a cost change of 0.1 (10%) or more. Defaults to 0.05 (5%).
aggregate	String	Used to consolidate cost model data. Passing an empty value for this parameter, or not passing one at all, returns data by an individual asset.
filterClusters	String	Comma-separated list of clusters to match; e.g. cluster-one,cluster-two will return results from only those two clusters.
filterNodes	String	Comma-separated list of nodes to match; e.g. node-one,node-two will return results from only those two nodes.
filterNamespaces	String	Comma-separated list of namespaces to match; e.g. namespace-one,namespace-two will return results from only those two namespaces.
filterLabels	String	Comma-separated list of annotations to match; e.g. app:cost-analyzer, app:prometheus will return results with either of those two label key-value-pairs.
filterServices	String	Comma-separated list of services to match; e.g. frontend-one,frontend-two will return results from only those two services.
filterControllerKinds	String	Comma-separated list of controller kinds to match; e.g. deployment,job will return results with only those two controller kinds.
filterControllers	String	Comma-separated list of controllers to match; e.g. deployment-one,statefulset-two will return results from only those two controllers.
filterPods	String	Comma-separated list of pods to match; e.g. pod-one,pod-two will return results from only those two pods.
filterAnnotations	String	Comma-separated list of annotations to match; e.g. name:annotation-one,name:annotation-two will return results with either of those two annotation key-value-pairs.
filterContainers	String	Comma-separated list of containers to match; e.g. container-one,container-two will return results from only those containers.
