I have an intstallation, where one Master node (A) and 4 child nodes (B,C,D,E).
There is also agent, which was added to node B.
One day I linked tamplate to this agent through Master Node and next before databases was synchronized I linked the same tamplate to the same host directly through Child Node.
When I discovered my mistake I remove this agent from Child node. Agent disappeared from Master node to.
Next I checked what is in databases, and I discovered, that in master node database not every items and applications referenced to deleted agent was deleted.
Chiled node database looks fine.
According that I have few question:
1. Can I delete this items and application directly from database?
2. Did Zabbix work fine in this situation? Shouldn't Zabbix have same mechanisms, to protect databases inconsistency ?
