/* --------------------
|
|
* ipmitool_sensor_data: outgoing message
|
|
* --------------------
|
|
*
|
|
* The sensor data is formatted in a json style string that is sent
|
|
* to the hardware monitor daemon on the active controller as
|
|
* specified by the aformentioned configuration command.
|
|
*
|
|
* The following is a brief 3 sensor example of the expected
|
|
* ipmitool output and json string conversion that is sent to
|
|
* hardware mon.
|
|
*
|
|
* ipmitool output:
|
|
*
|
|
* Temp_CPU0 | 54.000 | % degrees C | ok | na | na | na | 86.000 | 87.000 | na
|
|
* PSU2 Input | 0.000 | % Watts | cr | na | 0.000 | na | na | na | na
|
|
* Critical IRQ | 0x0 | discrete | 0x0080| na | na | na | na | na | na
|
|
* Fan_SYS0_2 | 4700.000 | % RPM | ok | na | 500.000 | 1000.000 | na | na | na
|
|
*
|
|
* Message Design Strategy:
|
|
* 1. Maintain all the ipmitool output information so that it is available
|
|
* to the hardware monitor for future enhancements without the need to
|
|
* change the client side messaging.
|
|
* 2. Validate the format of the ipmitool output and report on any errors
|
|
* observed in a status field of the response string.
|
|
* 3. Deliver an industry standard json string formated message
|
|
* 4. Provide an overall status field indicating any formatting errors
|
|
* detected in the sensor data output format. This is not a summary
|
|
* status of the sensor data.
|
|
* 5. minimize the amount of data sent
|
|
* - use short sensor record labels
|
|
* n = name
|
|
* v = sensor reading value
|
|
* u = unit format used when interpreting the data
|
|
* s = correlated status
|
|
* - ipmitool labels for thresholds but only include labels for values that are not 'na'
|
|
* unr = Upper Non-Recoverable
|
|
* ucr = Upper Critical
|
|
* unc = Upper Non-Critical
|
|
* lnc = Lower Non-Critical
|
|
* lcr = Lower Critical
|
|
* lnr = Lower Non-Recoverable
|
|
*

* Json String: sensor data excluded
