Displays the configuration information of database-related data tables used on the page in a list format.

Data Node

• Create Data Table: Users can create new custom data tables based on existing data sources, supporting up to 10 data tables. The creation information is roughly as follows:
  • Name: Supports Chinese, English, numbers, and underscores, with a maximum length of 10 characters
  • Data Table Set: Supports user-created data table sets, in the format of database.data_table_set
    • Options: flow_metrics.vtap_flow*, flow_metrics.vtap_app*
  • Original Time Granularity: The original time granularity of the data table set. The system currently supports 1m (one minute) and 1s (one second) by default
  • Time Granularity: The data table will be aggregated and calculated based on the selected time granularity
    • Options: 1h (one hour), 1d (one day)
  • Retention Period: Set the data retention time
  • Additive Metric Aggregation: If the original data table uses sum, only sum can be selected; if the original data table uses max/min, only max/min can be selected
  • Non-additive Metric Aggregation: todo
• Edit: Supports modifying the retention period of the data table
• Delete: Only supports deleting user-defined new data sources
• Note:
  • The system has 15 default basic data tables, which cannot be deleted
  • For metric-type (flowmetrics) and log-type (flowlog) data tables, minute-granularity data is retained for 1 week by default, and second-granularity data is retained for 1 day by default. Expired data is automatically deleted, and users can set an appropriate retention period accordingly
  • PCAP data is retained for 1 week by default. Data older than 1 week will be automatically deleted, and users can set an appropriate retention period accordingly
  • Monitoring data in the system is retained for 1 week by default. Data older than 1 week will be automatically deleted, and users can set an appropriate retention period accordingly
