1. Data Node

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

Data Node

• Create New Data Table: Users can customize new 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 Collection: Supports user-created data table collections, presented as database.data_table_collection.
    • Options: flow_metrics.vtap_flow*, flow_metrics.vtap_app*
  • Original Time Granularity: The original time granularity of the data table collection. The system currently supports 1m (one minute) and 1s (one second) by default.
  • Time Granularity: The data table will perform aggregation calculations based on the selected time granularity.
    • Options: 1h (one hour), 1d (one day)
  • Retention Period: Set the data retention period.
  • 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, none of which can be deleted.
  • Metric data tables (flowmetrics) and log data tables (flowlog) have a default retention period of 1 week for minute-granularity data and 1 day for second-granularity data. Expired data is automatically deleted. Users can set an appropriate retention period based on this.
  • PCAP data is retained for 1 week by default. Data older than 1 week is automatically deleted. Users can set an appropriate retention period based on this.
  • Monitoring data in the system is retained for 1 week by default. Data older than 1 week is automatically deleted. Users can set an appropriate retention period based on this.
