Description
Number of neighbors of a device
Description
The percentage of data packets generated
by motes (or accepted via send API) that
the manager received.
The ratio of number of acknowledged
packets by the total number of packets
transmitted.
The average time required for a data
packet to travel from the originating mote
to the manager.
Total number of lost upstream packets
across all devices and sessions.
Current time of the gateway. Seconds since
Epoch according to system's real-time
clock.
This value is seconds elapsed since last up-
date of network statistics data. Statistics
are averaged over a period of 15 minutes.
0 – Normal, 2 – WirelessHART queue or
stack is full.
Number of native WirelessHART devices
(excluding gateway and wired instruments
[i.e. sub devices]).
Number of total devices in the network (ex-
cluding gateway but including wired instru-
ments [i.e. sub devices]).
Number of live devices in the network (ex-
cluding gateway but including wired instru-
ments [i.e. sub devices]).
