Hello,
I have searched to see if this has been answered to no avail.
I have a Server 2022 VM that is being monitored.
It has a LAN interface, X.X.X.X and a iSCSI interface Y.Y.Y.Y
In the event log I see message after message that alternates between
“IP: X.X.X.X → Y.Y.Y.Y”
and
“IP: Y.Y.Y.Y → X.X.X.X”
Can someone tell me what this signifies?
The message provides no additional information and the server appears to be running correctly.
So we’re detecting a different IP address each time we poll or discover the device. Does the hostname have multiple IPs associated with it?
Thank you for the reply.
Yes, the LAN is on one interface, and there is an iSCSI connection on another.
I wondered if that was the case, so to experiment I disabled the iSCSI interface in the port configuration within LibreNMS. The messages stopped filling the event log.
Is this anything to worry about or is it expected behavior?
Well expected behaviour in so far as if the device tells us it’s got a different IP, we update and record that.
Expected that it should be returning a different IP all the time then no. You’ll need to look at why a dns lookup for the hostname is returning different IPs or using different interfaces each time.
This makes the most sense. I’ll double check the dns side of things. Thank you!
