What is hwmWhyReboot?

This OID reports the reason for the last system reboot as text, or null if the system has not rebooted since startup. Operators check this to diagnose unplanned outages, confirm maintenance reboots, or troubleshoot stability issues. A typical value like 'power failure' or 'software update' explains why the device restarted.
