I have different PLC connected to ignition through OPC-UA , during configuration we have to accept trusted certificate in each PLC.  
Each certificate had expiry data ..  
Question: is there any way to get these expiry data to be able to manage it automatically, means for example send notification one month before expiry data !!

```auto

```

No, nothing like that on the Ignition side right now. It would have to be a feature each server provides.

We consider Ignition as Hub now 😍 .. It would be good to get this value in `[System]Gateway/OPC/Connections/PLC/CertificateExpiry`
