{"storageSummary":{"binariesSummary":{"binariesCount":"703","binariesSize":"882.39 MB","artifactsSize":"3.41 GB","optimization":"25.23%","itemsCount":"4,126","artifactsCount":"1,917"},"fileStoreSummary":{"storageType":"file-system","storageDirectory":"/jfrog_uat_nfs/binaries","totalSpace":"1.30 TB","usedSpace":"1.23 GB (0.09%)","freeSpace":"1.30 TB (99.91%)"},"repositoriesSummaryList":[{"repoKey":"sbt_remote-cache","repoType":"CACHE","foldersCount":0,"filesCount":0,"usedSpace":"0 bytes","itemsCount":0,"packageType":"SBT","percentage":"0%"},{"repoKey":"test7.mvlo","repoType":"LOCAL","foldersCount":0,"filesCount":1,"usedSpace":"128 bytes","itemsCount":1,"packageType":"Maven","percentage":"0%"},{"repoKey":"scripttestkp.rplo","repoType":"LOCAL","foldersCount":0,"filesCount":0,"usedSpace":"0 bytes","itemsCount":0,"packageType":"RPM","percentage":"0%"},{"repoKey":"test7.grvr","repoType":"VIRTUAL","foldersCount":0,"filesCount":0,"usedSpace":"0 bytes","itemsCount":0,"packageType":"Gradle","percentage"
