|Title||HW/SW Inventory: Do not overwrite inventory tree if ALL data sources of a host fail|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Compatible - no manual interaction needed|
If a host has multiple data sources and ALL of these sources have an exception like empty data, connection problems or timeouts then the inventory tree won't be overwritten. This may reduce flapping inventory history entries.
If all sources fail the HW/SW Inventory service reports Cannot update tree WARN.
Note: This also concerns hosts with exactly one data source. If this source fails the inventory tree won't be overwritten, too.
