Lost traffic history on Ethernet interface

[Kamrang]

Hi,

Please help me, I lost interface history data on some of my devices, even though the devices were never re-added or removed and I didn’t find any logs in librenms, I only found the voting increase history in the same month as in the picture below:

Most likely the ifIndex values changed meaning the ports got removed and re-added. Look at eventlog for the device to see if it shows ports being removed and re-added.

Some devices don’t honour static ifIndex values so you need to change the port association mode in Device → Settings → SNMP

Thank you for your answer, I will take the time to read the log and find out more. I will come back later.

I’ve checked but there are no logs showing the port being recreated or anything like that.
