There are 4 same templates:

• HPE ProLiant BL460 SNMP
• HPE ProLiant BL920 SNMP
• HPE ProLiant DL360 SNMP
• HPE ProLiant DL380 SNMP

These are exactly same and duplicate of each other except the name.

There is a very similar generic template named "HP iLO SNMP" This template is only slightly different.

• It is missing "Network interface discovery"
• It has some extra items such as ICMP Ping and some SNMP objects

There is no need to have separate templates as iLO is iLO on all servers. These templates are querying iLO and independent of the server model.

I spent time trying to understand which template to use and this change will save countless hours in maintenance and reduce confusion between users.

I asked about this in forum also, but nobody answered as of yet:

I made an issue report, but I was forwarded here instead:
