Overview

Going to start this list of troubleshooting tips in case it's helpful for anyone.

Fault Zero

Although I don't really keep an inbox zero, when troubleshooting I find it's very helpful to have minimal list of active errors/faults in an environment. In our ACI fabric we have a few which I eventually need to resolve but hopefully you can see it's quite easy to spot a fault such as a config error. APIC will also show you a scoped view e.g. all the faults in a tenant.

Compare that with our Intersight/UCS account and you can see as the list grows into 10s/100s (hopefully not 1000s?) it can be very hard to determine which faults are relevant to your current troubleshooting session.
