Monitor Exadata Temperature

Ambient operating temperature for exadata machine can be monitored on the EM12c exadata page. In EM12c, There is a click on the top of the exadata figure that will show you the current temperatures of the components. If the temperature is above 32 degrees then a critical alert is generated and an email is automatically sent. You can also query this information on command line.

EXADATA HW: High Temperature (CL_TEMP) Alert From One Of The Cell Nodes (Doc ID 1544182.1)

From the command line
Just for the current node:

[root@hostdbadm02 ~]# ipmitool sensor list | grep degree | grep T_AMB
T_AMB            | 22.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na   

To monitor all of the compute nodes and the cell server temperatures execute the following :

[root@hostdbadm01 ~]# dcli -g /root/all_group -l root ipmitool sensor list | grep degree | grep T_AMB
hostdbadm01: T_AMB            | 21.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na
hostdbadm02: T_AMB            | 21.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na
hostdbadm03: T_AMB            | 21.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na
hostdbadm04: T_AMB            | 23.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na
hostceladm01: T_AMB            | 22.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na
hostceladm02: T_AMB            | 22.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na
hostceladm03: T_AMB            | 22.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na
hostceladm04: T_AMB            | 21.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na
hostceladm05: T_AMB            | 21.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na
hostceladm06: T_AMB            | 22.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na
hostceladm07: T_AMB            | 23.000     | degrees C  | ok    | 3.000     | na        | na        | na        | na        | na

Or you can use the following command. This one is much better.

[root@hostdbadm01 ~]# dcli -g /opt/oracle.SupportTools/onecommand/all_group -l root 'ipmitool sunoem cli "show /SYS/T_AMB" | grep value'
hostdbadm01: value = 18.750 degree C
hostdbadm02: value = 19.000 degree C
hostdbadm03: value = 19.500 degree C
hostdbadm04: value = 20.500 degree C
hostceladm01: value = 21.250 degree C
hostceladm02: value = 21.000 degree C
hostceladm03: value = 20.750 degree C
hostceladm04: value = 20.500 degree C
hostceladm05: value = 20.250 degree C
hostceladm06: value = 21.250 degree C
hostceladm07: value = 21.500 degree C
