[//]: # (werk v2) # DCD: Not respecting "Validity of missing data" setting key | value ---------- | --- compatible | yes version | 2.4.0b1 date | 2024-01-23T14:05:03+00:00 level | 1 class | fix component | checks edition | cre This fixes disappearing hosts in case of temporarily missing data around the time when a cleanup background job is run (around midnight). In case a piggybacked host temporarily did not receive any data while the background (cron) job <code>cmk --cleanup-piggyback</code> was executed, a subsequent run of the DCD would not respect the "Validity of missing data" setting, wrongly removing the affected host from the monitoring configuration.
