SERVERSCHECK: Built-in Temp Sensor Not Discovered

Details

    • Bug

    Description

      The built-in temperature sensor which is gateway sensor 1 is not shown when a hub is attached and a sensor is connected to hub port 1. The built-in temperature sensor is shown if a sensor is not plugged into hub port 1.

      The sensorscheck MIB reverses the names for the sensor name and value depending on whether the sensor is connected directly to the gateway or connected via a hub. Discovery appears to be looking for both.

      Temp on GW : sensor1Value sensor1name
      Sensor1 on hub: sensor1value sensor1Name

      The debug from discover.php appears to show the gateway sensor 1 (built-in temperature sensor) being discovered, however, the debug from poller.php does not appear to find or poll the sensor.

      Debug output of the discovery and the poller are attached.

          Case sensitive Oid names compare.

          Should be fixed after r11315.
          After update (on rolling channel) need db schema update and rediscovery device.

          Please make and attach additional information about the device:

          • full snmp dump from device:

            snmpwalk -v2c -c <community>  --hexOutputLength=0 -ObentxU <hostname> .1 > myagent.snmpwalk
            snmpwalk -v2c -c <community>  --hexOutputLength=0 -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk

            If device not support SNMP version 2c, replace -v2c with -v1.

          • If you have problems with discovery or poller processes, please do and attach these debugs:

            ./discovery.php -d -h <device>
            ./poller.php -d -h <device>

          • additionally attach device and/or vendor specific MIB files
