HostName is different in discovery and Actual

[Kamal Sharma]

Hi Team,

I am doing a windows server discovery in which getting the hostname different in discovery (CMDB) but in Actual  (on Host) is different.

Hostname In discovery (Under Device tab) or CMDB is ---  ip-172-xx-xx-xxx

Hostname in Actual  (On server) -- SYsxxxxAWS

What is the root cause for this, please help me to correct it.

Hi,

Do you have any reconciliation rules in place which are not allowing to update this data?

Thanks,
Ashutosh

Hi Ashutosh

No, there is no rule.

Also after making the "DNS or NetBios is trusted hostname source" false, issue got resolved.

Hi Kamal,

There is a property called glide.discovery.hostname.wmi_trusted.

This determines whether discovery will use reverse DNS lookup, or will use WMI to return the name.

By default this property is set to false.

I have seen companies where the DNS is not so "healthy" and consequently using WMI is the better way to go.

Regards

Martin

Hi Martin

Yes, you are right as this is the cloud env.

I made glide.discovery.hostname.wmi_trusted as true but still no luck to change or update.
