Nginx process classifier's probe's sensor inserts directly into the CMDB, bypassing IRE, for cmdb_ci_lb_nginx records - Discovery source /First Discovered not populated - Known Error

Nginx process classifier's probe's sensor inserts directly into the CMDB, bypassing IRE, for cmdb_ci_lb_nginx records - Discovery source /First Discovered not populated Description The "Nginx" discovery process classifier triggers the "SSHCommand-Nginx - Get Configuration" probe, and the sensor uses script include "Nginx" and "LBModule" to populate/update the Nginx Load Balancer [cmdb_ci_lb_nginx] table records directly, bypassing the CMDB IRE, and so the usual IRE reporting/tracking fields/tables are not all updated.

In the "LBModule" script includes, the functions are only updating last_discovered for the various load balancer tables. discovery_source and first_discovered are not being populated/updated.

This impacts reporting, and use of more advanced CMDB IRE reconciliation functions.

Steps to Reproduce

Using horizontal/IP-based "Discovery" plugin Discover a linux server that has Ngnix web server/load balancer running. The process classifier will trigger the "SSHCommand-Nginx - Get Configuration" probe, and the sensor will update cmdb_ci_lb_nginx records. Inspect the records to confirm the usual IRE fields are not all updated. e.g. 2022-09-18 01:17:20 mid_server_user 2022-08-13 01:17:21 mid_server_user 2022-09-18 01:17:20

Expected behaviour: Even non-Pattern probe sensors should be using IRE for this kind of insert/update, or at least populate the same reporting fields.
