The only way is to try to figure out what the original ifIndexes were for the ports and move the RRDs around.

You could probably reconstruct this by looking at the eventlog to see the ifAlias changing for various ports, but it might not be worth the effort.

If you don't do this, you should delete the RRDs, because their data is now invalid.

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”

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

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
