    Description

      Hello Observium Team,
       
      We are currently running a Proof of Concept to determine whether we can replace PRTG with Observium. During this process, we noticed two issues that we believe are bugs:
       
      Cisco NX-OS Switches in ACI Mode (Cisco SDN Fabric): A connector/SFP is always reported as present.
      While Cisco NX-OS in non-ACI mode works perfectly, for NX-OS switches in ACI mode, Observium always sets ifConnectorPresent => true, even though no transceiver is installed. It seems like something is missing or incorrect in the mapping. I haven't found any clear leads in the Observium files. The only clue is a difference in the output of the "show interface status" command:

      • sfpAbsent (NX-OS)
      • sfp-absent (NX-OS ACI Mode)

      Perhaps the mapping needs to be extended?
       
      Furthermore, transceiver information for NX-OS switches in ACI mode is not listed under https://<your-observium>/transceivers/. I suspect that the information is provided differently in ACI mode and that a mapping or similar adjustment is required.
       
      Does Observium offer any features to perform rewrites on PHP files or similar modifications?
       
      We are using the Observium version provided by Adam for our PoC.
       
      Thank you!
