The Operating System uptime may not increase while the endpoint is asleep or hibernating.
Sensor Uptime:
The amount of time since the Carbon Black service started.
NOTES:
* Because the "Host Uptime" value may not increase when the endpoint is asleep or hibernating, the "Sensor Uptime" value can legitimately be higher than "Host Uptime".
* If the "Sensor Uptime" is consistently a low number, it may indicate an issue with service stability.
Host Uptime:
The amount of time the operating system has been running as reported by the operating system itself.
NOTE:
* This may not increase when the endpoint is asleep or hibernating.
