DNS & Net

DNS and lower-level network events matter when the visible exception is downstream of resolution failure, socket churn, or slow network setup.

DNS and net timeline
6ms   DNS lookup for billing-db.internal
17ms  TCP connect to collector.internal:443
41ms  Error surfaced during upstream request

Enable this layer when network diagnosis matters. Leave it off if higher-level HTTP and database events already explain the failure path well enough.

Database Queries

Record query order and duration so missing rows, timeouts, and constraint failures have useful surrounding context.

Database Support

Database capture expectations for relational and document stores commonly used with errorcore.
