In a similar vain...I'm using Cacti to graph services based on firewall mark. When a fwmark is removed I tell Cacti to reindex the LVS SNMP data so each data source is still groking the right part of the SNMP tree. This does that...but (today at least) also edited the path to the RRD for each data source to use the previous data source's RRD. I then became unhappy as I watched Cacti trash all my pretty graphs. How do other folks handle this case when a service disappears from LVS with Cacti?
