Schema: Connection Log Tables

This chapter contains information on the schema and supported joins for connection data.

For more information, see the sections listed in the following table. The Version column indicates the Database Access versions supported by each listed table.

Table 7-1 Schema for Connection Log Tables
See...	For the table that stores information on...	Version
connection_log	Individual connections. Supersedes deprecated table `rna_flow`.	5.0+
connection_summary	Connection log summaries. Supersedes deprecated table `rna_flow_summary`.	5.0+
si_connection_log	Individual connections. Used for security intelligence.	5.3+

connection_log

The connection_log table contains information on connection events. The Firepower System generates a connection event when a connection between a monitored host and any other host is established; the event contains detailed information about the monitored traffic.

The connection_log table supersedes the deprecated rna_flow table starting with Version 5.0 of the Firepower System.

For more information, see the following sections:

connection_log Sample Query

The following query returns up to 25 connection event records from the connection_log table, sorted in descending order based on packet timestamps.

SELECT first_packet_sec, last_packet_sec, initiator_ipaddr, responder_ipaddr, security_zone_ingress_name, security_zone_egress_name, initiator_port, protocol_name, responder_port, application_protocol_id, client_application_id, web_application_id, url, url_category, url_reputation

WHERE first_packet_sec <= UNIX_TIMESTAMP("2011-10-01 00:00:00" ) ORDER BY first_packet_sec

DESC, last_packet_sec DESC LIMIT 0, 25;

connection_summary

The connection_summary table contains information on connection summaries or aggregated connections. The Firepower System aggregates connections over five-minute intervals. To be aggregated, connections must:

have the same source and destination IP addresses
use the same protocol
use the same application
either be detected by the same managed device (for sessions detected by managed devices with Firepower) or be exported by the same NetFlow-enabled device and processed by the same managed device

The aggregated data in a connection summary includes the total number of packets and bytes sent by the initiator and responder hosts, as well as the number of connections in the summary.

The connection_summary table supersedes the deprecated rna_flow_summary table starting with Version 5.0 of the Firepower System.

For more information, see the following sections:
