Device Availability Report of Router

Device Availability Report of Router

Hi

I am monitoring routers & scheduled a report on device availability.

It gives router up time but not based on interfaces.

Can some one please help me solve this.

Can I have report based on serial interfaces & ethernet interfaces. (Link Uptime ) instead of just router uptime?

As current uptime shows some report but difficult to find out which link or interface was down from that report.

Thanks in advance
