### 2.3 STATE_DB keys and value ###

The key used to represent a PCIE device for storing its AER stats in STATE_DB is of the format `PCIE_DEVICE|<Id>|<Bus>:<Dev>.<Fn>`.
For every device, AER stats will be stored as key, value pairs where key is of the format `<severity>|<AER Error type>`
The key used to represent a PCIE device for storing its attributes in STATE_DB is of the format `PCIE_DEVICE|<Bus>:<Dev>.<Fn>`.
For every device, AER stats will be stored as key, value pairs where key is of the format `<severity>|<AER Error type>` and the device ID will be stored with key `id`.

Example) For a PCIe device with Bus: 1, Dev: 0, Fn: 1, Id: b960 the STATE_DB entry will be as below:
