`sn_agent.disco_ci_clobber_of_agentless_disco_threshold_days`

Sets how many days can pass before agent discovery can replace an existing CI found by agentless Discovery. The default is 14 days; once exceeded, Enhanced Discovery can overwrite the CI with newer data when the related clobber-prevention setting is enabled.

Default: 14
Type: integer
Application: Not stated

Key questions about this property

The answers below summarize the purpose, scope, default effect, and review scenarios for this property.

What does it do?	Sets the number of days after agentless Discovery during which an existing CI is linked instead of rediscovered by an agent, when the related clobber-prevention setting is enabled.
What area does it affect?	Agent Client Collector Discovery
What does the default mean?	The default value is "14", which sets the baseline numeric behavior for this property.
When should you review it?	Review when adjusting how long agentless Discovery data takes precedence over agent-discovered data in the CMDB.

Property record

Facts stated in the ServiceNow documentation. No out of the box record has been read from an instance yet.

Property name	`sn_agent.disco_ci_clobber_of_agentless_disco_threshold_days`
Type	integer
Application	Not stated
Default value	`14`
Description	The maximum number of days since an existing CI has been discovered using Agent-less Discovery where the existing CI links instead of re-discovering it using the Agent. This takes effect when disco_disable_ci_clobber_of_agentless_disco is true and it has been an extended period of time (over 14 days, by default) since a non-ACC discovery_source (like ServiceNow) has discovered the CI. Once this threshold is exceeded, Enhanced Discovery is allowed to execute and clobber an existing CI regardless of whether a CI has been previously discovered by a non-ACC discovery_source. This enables the most recent discovered data to be present in the CMDB.
