I've been handed the reigns of an old G8 DL380e that runs the office I work at. I found the HP Array Config Utility, which lets me keep track of the drives, and I found the HP ProLiant Integrated Management Log Viewer, which has been helpful (had PSU #2 flaking out and didn't know it until I saw errors there).
Does HP or a third-party company have software that lets me monitor CPU temps and system fan speeds?
I'd like to be able to dig into it a bit more, but everywhere else I turn I need a subscription for this, or a subscription for that.
