# Enhancing the CMDB with host data found in logs

When Health Log Analytics streams logs, it extracts host data from the
log events. If host data is discovered that doesn't match the information in the Configuration Management Database (CMDB), the system creates a configuration item (CI) candidate
based on the data it found in the logs for you to review.

After reviewing a CI candidate, you can choose to either add it to the CMDB or dismiss it as
irrelevant. The Log-Based CI Candidates table lists all CI candidates that
Health Log Analytics has created, sorted by system update time. The
Operation column shows the suggested action to take on each CI candidate.
You are automatically notified when there are new CI candidates for your consideration. For more
information, see [Add log-based CIs to the CMDB](https://www.servicenow.com/docs/Bbj_x9V~s4lhDyDtryPeJg "Keep the Configuration Management Database (CMDB) updated with host data discovered in your logs by adding log-based configuration items (CIs) to it.").

For a description of the related system properties, see the "logsourceinfo (CMDB)" section in
the [HLA System Properties \[KB0869842\]](https://support.servicenow.com/kb_view.do?sysparm_article=KB0869842) article in the Now Support Knowledge Base.

This feature is supported in the Health Log Analytics application, Version 22.0.12 - December 2021 and later, available from the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home). You can use it on the ServiceNow AI Platform using the Rome Patch 6 release
(scheduled to be released on January 27, 2022) or later.
