Following is an bash script to monitor data center temperature via SNMP query from Emerson UPS. We can monitor the temperature via manageable ups builtin feature as well, but since i was required to do some extra functions which were not supported by the ups web panel, so i made following. although i removed few functions, but sharing it for general public as an example.
Following is an example code of SNMP query of temperature monitor from Emerson UPS ITA 10k UPS. [Sensor IRM-S02TH-001]
