Data in CloudFabrix's AIOps platform is organized as datasets. Each dataset is associated with a unique tag. A tag allows to fetch the data related to that dataset and is mandatory while making queries so that only related data from dataset is fetched. For example, a CaaSDataset class provides methods to fetch all the tags and their associated metadata. There are also convenience methods (pre-defined functions/API) are provided for well known tags including Inventory, Incidents, Alerts, etc. Optionally filters defined in the form of CFXQL can be specified as argument.
