Yes, probably all cameras use same snmpEngineID.. This Oid main for check duplicate devices.. (set of sysName+snmpEngineID)
Dana, please make SNMP dump from two different cameras and send me:
snmpwalk -v2c -c <community> --hexOutputLength=0 -ObentxU <hostname> .1
myagent.snmpwalk snmpwalk -v2c -c <community> --hexOutputLength=0
-ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk

Looks like they have the same engine ID - it's what the message is saying...

Hi,
Do the devices have different snmpEngineIDs? It should allow you to add multiple devices with the same sysName.

When I add a Vivotek camera to Observium, works great for one, but when I try to add another one, the System name is the same (in this case h.264 mega-pixel network camera) and it will not add. The name of the device is different, what Observium “pulls in thru SNMP” is the same.
Already got device with SNMP-read sysName (h.264 mega-pixel network camera) and 'snmpEngineID' = 80005BA9017F000001 (jq-office-lobby-cam01.bcp.cat.com).
I see in JIRA that we are supposed to be able to add more devices with the same system name, but this is not working for the version I have of Observium 20.4.10371 (stable).
It is my “belief” that Vivotek is reporting back it’s system name to SNMP incorrectly. I do not really “care” if the System Name is wrong, but I cannot add another camera at all.
This is what is in the camera configuration and I don’t see any other location for a host name.
If I do an snmpwalk on the device:
SNMPv2-MIB::sysName.0 = STRING: H.264 Mega-Pixel Network Camera
Observium is pulling what the camera is giving …. So is there a way to change this in the database or a way to say add it anyway?
