Assumption:
Upper Warning threshold is enabled.
Upper Warning = 20 (degrees Celsius)
Deassertion Hysteresis = 3 (degrees Celsius)
"Deassertion" level = 20-3 = 17 (degrees Celsius)
When the PX detects that a temperature sensor's reading drops below
20 degrees Celsius, moving from the "above upper warning" range to the
"normal" range, either of the following may occur:
 If the temperature falls between 20 and 17 degrees Celsius, the PX
does NOT turn on the "deassertion" action.
 If the temperature drops to 17 degrees Celsius or lower, the PX turns
on the "deassertion" action to announce the end of the "above upper
warning" state.
Ways to Probe Existing User Profiles
This section indicates available ways to query existing user accounts on
the PX.
 With SNMP v3 activated, you get the "user unknown" error when the
user name used to authenticate does not exist.
 Any user with the permission to view event rules can query all local
existing users via JSON RPC.
 Any user with the permission to view the event log may get
information about existing users from the log entries.
 Any authenticated users can query currently-existing connection
sessions, including Webcam-Live-Preview sessions, which show a
list of associated user names.
