With a multi-source CMDB , data can be imported through different ways , ServiceNow provides many tools and capabilities to import data .
IRE (Identification and Reconciliation engine ) is the ServiceNow capability that can perform identification and reconciliation processes across all the different data sources .
Data needs to meet all mandatory requirements from IRE before inserting that data to the CMDB .
When CMDB data is imported with standard data source / transform map , and you are facing import issues (data not imported , attributes not populated …) , the default message log level , in the system logs module , is not providing enough insights to understand what is happening at IRE level , what data is not meeting the IRE requirements .
In order to identify the IRE message logs :
Go to logs (System Logs > System Log > All) and set “source” with identification_engine
In order to enable the IRE logs , you have to create this property glide.importlog.log_to_table and set it to true .
This system property will write the information-level log messages into the import_log table .
These logs can be challenged with data owners .
This property produce more verbose logs , enable it only in the analysis period , and turn it off after that .
