Delete and re-create it, my opinion. I don’t know any workarounds to restore the graphs with the proper ifIndex numbers.

Hi Shawn,
 
Looks like you did not have persistent ifindex configured on your IOS-XR device.
Try with: “snmp-server ifindex persist”

Betreff: [Observium] Graphs not collecting data after a route reboot

After having a Cisco ASR9001 router reboot over the weekend, some graphs are no longer displaying data and new graphs have been created.
 
Some graphs like processors, memory, etc.  are populating correctly, while others like traffic and ports are empty.  This router has been in observium
 for years.  The only thing that changed was a reboot over the weekend due to a power issue.  No upgrades, changes, etc.
 
In some cases, the "old" graph for an interface is showing nothing, but a new graph for that interface seems to have been automatically created and
 is now showing data.
 
Is there any way to fix this?  I could probably delete the device completely and re-add it, but I hate to loose all of the historical data from it.
 
I can post links to screenshots to illustrate
 
thanks
