Overview

All jobs in these modules run queries against the Data Flow Probe's PostgreSQL database to retrieve network connectivity information inserted by the Host Resources/Applications and/or TCP By Shell/SNMP and/or Collect Network Data by NetFlow jobs.

For details on Host Resource jobs, see Host Resources and Applications Discovery.

The Data Flow Probe includes a built-in PostgreSQL database so there is no need to install a separate PostgreSQL instance for NetFlow. Instead, data is saved to a dedicated scheme (called netflow for historical reasons).

NetFlow is supported by various Cisco routers and can be used to monitor traffic capacities and flows initialization or termination.
