ver 5.0 Itemprototype usage

[Blindbg]

Hello Zabbix Guruz

I'm new to Zabbix
currently using jmxtrans (https://www.jmxtrans.org/) with Grafana
would like to switch to Zabbix (with Grafana)

now, when using Discovery Rules LLD

I expect dummy "Item Prototypes" to be created for me, so I can then modify them according to my needs

However, I think that this is not the intended behavior, and "Items" should just appear as "red colored" in host "Items" list

I do not see any jmx attributes appear as "red ghosts" in my host "Items" list, before I define them as "Item Prototypes"

Have I misunderstood the whole Discovery idea?

thank you for explaining

Thanks cyber

I get what you are saying.
Let me explain my confusion

use JMX monitoring...
create template and 1 rule for discovery of attributes under java.lang (application Core) and other rule for attributes under java.nio (application IO)
to be as generic as possible have 1 item prototype in both name: {$JMXDESC} and key jmx[{JMXOBJ},{#JMXATTR}]

Can you do that without being told that you already have that key in use?

Blindbg Yes but you have a typo you forgot the hash character before JMXOBJ... {JMXOBJ},{#JMXATTR}] -> {#JMXOBJ},{#JMXATTR}]
That is probably why you get same key error because you have same key for every item
