Interface number changed



Hi, some days ago I've involuntary disabled one of the two network interface on my server. Then I turned it on again but it looks like the interface has change its OID or interface number and the relative sensor reports an error. Of course I can create a new correct sensor but I would lose all historic data. How can I solve this problem?

Thanks in advance for help cotus

Dear Cotus,

please see How can I move the historic data of one sensor to another ?. The article will show one "official supported" option and another one which involves editing the configuration file, which would not be supported.

Best Regards.
