I have the two question about performance and hardware device path
1. I face the problem about the network card device path, I find some of the path is not in use, and want to delete them .
Let me take the sample:
The old ethernet address is in use eth0, but it is not in use in future. I want to add the new card assign the eth0. how can I delete and assign to new device.
2. How to check the history of performance for Disk and Memory ?
