    Description

      Since XOS 22.3.1.4 or some versions below Extreme added the feature to pull dBm values from the ports. Works "ok" so far... only interger values are support crap.

      Observium is supporting this feature but during the convertion of this value it fails.

      Converted DBM value: -7.0E-6 W -> FALSE
      

      And sensor_unit is wrong. Output is dBm. Attached debug log and a CLI output from the transceiver.

          [OBS-2763] Extreme XOS dBm convert issue

          This sounds more like an SFP+ module bug instead of an issue in the whole firmware of EXOS. Did you try other vendor SFP+ modules?

          FYI... in XOS 31.6.1.3 this is still not fixed for all SFP+ modules.  A FiberStore version of an Extreme CW57-10G-80-1570 continues to quantize reported Rx power levels to integer microwatts, thus losing a LOT of precision in the Observium graphs.

          great!

          Extreme released new firmware which contains a bug fix.

          ExtremeXOS 22.7.1.2

          Update: Extreme confirmed this bug opened a official bug ticket for this. Fetching values via SNMP for "entPhySensorEntry" gives incorrect values. CR#xos0073216

          We will open a ticket for this issue at Vendor support :/
