To summarize: this nice new feature is not yet fully implemented for all record types; also, camonitor misses an option to specify the request type to make this useful. I tried to add it but it doesn't work.
We are assuming when the release note states "support subscriptions that get events whenever a property of the PV changes."Note that event types concern properties of PVs as CA sees them. CA has no notion of records or fields.
Does it mean if the meta data i.e value of ioc:example:LOLOYou mean ioc:example.LOLO? ^changes and we were using probe or camonitor to monitor the ioc:example pv, it will change the value of LOLO since LOLO is a property of the pv.
Looking at 'camonitor -h' I see no option for specifying the DBR type, so it seems that --apart from timestamp and status/severity-- properties are not supported yet.
Cheers, Ralph
