    Description

      I want to make a feature suggestion for a config for the RX/TX Power section.
      Mostly the optical signal is meassured in dB i.e. on OTDR or optical transceiver datasheets or handover documentation for fibers or passive equiqment i.e. cables, connectors.

      Would it be possible to add an option to convert the units from mW into dB on the Webinterface and in the database? One table field for mW and another for dB so that both units can be also used for the alerting module. It could be a optional feature enabled in config.php.

      It's possible to calculate mW into dBm based on https://en.wikipedia.org/wiki/DBm or http://www.rapidtables.com/convert/power/mW_to_dBm.htm (easier).

      I'am pretty sure that using dBm units would help a lot of peope to improve their link stability if they can read directly the dB values from Observium instead of manually converting them into dB. Some devices are already telling us the dBm values but some are using mW. With a forced "convert mW to dBm" it would be possible to have a consistent unit state.

      What do you think about this?

          You must can update to the latest rolling svn version.

          or wait for next stable sync.

          Yes... as you said. You are on the latest stable and not rolling version.

          Hello, 

          I'm not seeing such option in my Observium:

          Ability added in r9367.

          See option in Global Settings -> Entities -> Ports (Convert Port DOM power sensors to dBm).

          @Obs Team: Do you have any feedback from your side for this feature request?

          @premchand: You mean that you also have mW units instead of dBm for Cisco devices? The Brocade is giving us the values as dBm, but Cisco not. So I'am pretty sure that a transformation of both would be a useful feature to convert each unit into the other one to have standard unit for this kind of information.

          same problem 

          my observium  now show sfp power in dBm
