Introduction:
Alarms from snmpcollector probe may only include IP address of devices being monitored in the alarm messages, this is due to that the device is not resolved into a valid name. By default snmpcollector has the default of publishByHostname=true and it retrieves the device name via SNMP polling.
Instructions:
1. You can modify snmpcollector raw config to set 'publishByHostname=false' and deactivate & activate snmpcollector probe. 

After that new QoS objects (new table_id) will be generated.

2. Contact local network/system administrator to add device name and IP mapping for network devices being monitored in both forward and reverse lookup zones in DNS server used by UIM server and any servers with nas probe deployed. 

If this is not possible, add this mapping in the hosts files in your UIM server (primary hub server) by default this should be: C:\Windows\System32\drivers\etc\hosts for Windows server 

If you have multiple nas probes on secondary hub, add static mapping on the secondary hub servers if DNS approach is not possible.

3. Clean up 
run ipconfig /flushdns on UIM server 

Open nas probe in UIM server and select Name Services tab, select Properties tab, make sure 'Enable Name serivces' and 'Use Default Name-Resolution..' are checked. 

Select Address table tab, drop any relevant records for network devices and force nas probe to perform lookup again.

If you have nas probe on secondary hub with snmpcollector, perform above in the secondary hub server instead.

4. Acknowledge all alarms from pollagent (snmpcollector) probe and check incoming alarms to have device name in the Host Name column and IP address in the Source column in alarm console.
