We've been trying to poll our Cisco Firepower 2100 (ASA) and Cisco Secure 3100 (ASA) to monitor the device power supply, fan and temperature sensor in our NMS via SNMP. Currently, we can only monitor device CPU and memory. Cisco TAC has confirmed that there's a bug (CSCvd33367) and it seem an engineering bug (Severity 6/Enhancement). Cisco TAC haven't resolved this issue in a long time (since February 2017) and there's no workaround.
We've raised this to our Cisco Account Manager to raise this to their engineering hoping this would resolved anytime soon. Below is a snippet from the said bug:
SNMP OID's for Disk, Fan and power supply
Description:
SNMP monitoring on the firepower is based on OID's. Actually firepower manages basic linux OIDs, customer would like to use also those OID's for monitoring Firepower status. Moreover, there is a more stringent need to have storage OIDs for pure ASAs which are not FMC managed to have disk monitoring in FMC.
Symptom:
The customer would like to use SNMP to monitor Fan, power supply and Raid disk status with the OID's for those features on the FP. He would like to know if those OID's can be included in future releases and that way he can monitor tose features using OIDs.
Conditions:
Firepower does not have OID's available for monitoring fan, power supply and Raid disk status.
Workaround: N/A
Further Problem Description: N/A
Note that its Severity is “6 Enhancement”, which means that Cisco Engineering is not looking at this behavior as a “bug” per se. That is, from Engineering’s viewpoint, the product is working as designed and this CDETS ID represents a request to enhance the original behavior. Feature enhancements are pushed by Sales account teams into Product Marketing, which prioritizes enhancement requests back to Engineering.
