(cross-post from fm-discuss) Hello. I'm a core developer for the net-snmp project. My particular area of expertise is sensors and my specific interest is populating HOST-RESOURCES-MIB and LM-SENSORS-MIB. Up until now, on most platforms I've been able to do it with kstat and/or picld library calls.
I'm currently working with T2000's and having little or no luck getting at the sensors. At best, I can program the ALOM to send me a trap, but I need to monitor the temperator sensors live. I've got a server room with cooling issues and if the temperature gets too high, I need to get the doors open and set up fans. I've been monitoring ambient temperature using SNMP graphing and monitoring tools. Hence, I'm interested in libtopo and whatever I can derive from it. Hell, I'll even write the damn code if someone will tell me where to pick up the information from the bus. In order to simplify our API, we ended up coding a HAL (Hardware Abstraction Layer) and moved the underlying nasty code underneath it. Hence, I welcome your effort to do the same thing for a Sensor Abstraction Layer and would like to get involved. For all three projects (net-snmp, libtopo, SAL) I need to be able to see the sensors on the bus and I'm coming up empty. My last hope was busstat and I'm seeing: #busstat -l Busstat Device(s): dram0 dram1 dram2 dram3 jbus0 jbc0 pciex_imu0 pciex_imu1 pciex_mmu0 pciex_mmu1 pciex_tlu0 pciex_tlu1 pciex_lpu0 pciex_lpu1 busstat -e of the various devices isn't giving me anything I recognize as being associated with sensors, and it doesn't appear to have any way of drilling down to lower layers. Am I missing something or can I simply assume that a T2000's sensors simply don't show up on the bus at all.
