Dataset management

Last Updated: Apr 11, 2018

Alarm and data query are the presentation of datasets, while datasets are the underlying data of the preceding controls. ARMS presents data in the form of dataset to conceal the details, such as the underlying data storage structure and mechanisms of compression storage, data backup, and data query. Therefore, you don’t need to understand how data is stored on the storage media. You only need to focus on how to use the data.

Dataset query

  1. In the left-side navigation pane of the console, choose Custom Monitoring > Datasets, and click Query Data on the right of the dataset to be queried.

    Note: On the “Datasets” page, besides the multi-dimensional datasets created earlier, datasets related to the alarm control are also displayed, and the names of these datasets are the same as the control names. Here, a multi-dimensional dataset is used as an example.

  2. On the Query Data tab, select the required dimension and click Query. Data is displayed in the form of data chart.

    • Query Policy: If you select Freshness First, your data is returned in real time but may be inaccurate because of the incompleteness. If you select Integrity First, your data is displayed after the system ensures that the data is accurate.

    • Zero Fill Policy: If this policy is selected, zeros are filled to the null values in your data.

    • Advanced Configuration: For the mapping table function, see Mapping table management.

  3. After data can be queried on the page, you can use the ARMS RESTful API to query data and use data in custom ways. For more information, see ARMS Open API overview.

  4. If the multi-dimensional data is stored, you can select Drill Down and click Query to view detailed data of each dimension. The ARMS Open API provides a Drill Down interface.
