The configuration management database (CMDB) API enables you to manage classes and variables for specific hosts.

List CMDB

You can see a list of stored host-specific configurations

URI: https://hub.cfengine.com/cmdb

Method: GET

Parameters:

  • fromEpoch (integer) Returns configurations with epoch value greater than set in the filter. Epoch is the sequence number of the latest CMDB change. In every API list request, cmdb_epoch will be present in the meta section, which contains the maximum epoch value among selected items. Optional parameter.
  • fromTime (timestamp) Include changes performed within interval. Format: YYYY-mm-dd HH:MM:SS or YYYY-mm-dd. Optional parameter.
  • toTime (timestamp) Include changes performed within interval. Format: YYYY-mm-dd HH:MM:SS or YYYY-mm-dd. Optional parameter.
  • skip (integer) Number of results to skip for the processed query. The Mission Portal uses this for pagination. Optional parameter.
  • limit (integer) Limit the number of results in the query. Optional parameter.
  • hostContextInclude (array) Includes only results that concern hosts which have all specified CFEngine contexts (class) set. Optional parameter.
  • hostContextExclude (array) Excludes results that concern hosts which have specified CFEngine context (class) set. Hosts that have at least one of the specified contexts set will be excluded from the results. Optional parameter.
