    Description

      Trigger prototype expressions for discovery rules "Temperature CPU Discovery" and "Temperaure Discovery" and host macros should be reviewed in default "Cisco UCS SNMP" template.

       

      In discovery rule "Temperature CPU Discovery", macros below are used but not defined in host macros :

      $TEMP_WARN:"CPU"
      $TEMP_CRIT:"CPU"
      $TEMP_CRIT_LOW:"CPU"

       

      In discovery rule "Temperaure Discovery" there are two issues.

      First, same macros are used regardless of sensor location :

      $TEMP_WARN:"Ambient" => 30°C
      $TEMP_CRIT:"Ambient" => 35°C

      I think these values are not appropriate to monitor IOH or server rear panel temperature. The result is that false positive problems are generated when monitoring an UCS server with default "Cisco UCS SNMP" template.

      Second issue is that $TEMP_CRIT_LOW:"Ambient" is used in prototype trigger expressions but not defined in host macros.
