26 CHAPTER 3 • SENSORS PAGE
Note
Despite having a green circle status, a device may have recorded communication er-
rors; despite having a red box status, some valid data may have been received.
Data
The Data status column contains an icon representing the data state of each sensor in the
list. The Data status for a sensor is based on:
Recent Data – The most recent data for each sensor is cached by Collector. The data in
this cache will expire based on system settings (by default after three times the collec-
tion frequency).
No Recent Data – If there is no recent data, the data status will return an error (icon
with a red square).
Slow Collection Jobs – If collection jobs are taking longer than the allowed time (as
determined by collection frequency), then the data status will change to an warning
state (icon with yellow triangle).
No Collection Jobs – If the sensor is enabled and no collection jobs are running, then
the status will be in the error state.
Missing Some Collection Jobs – If there are too many missing collection jobs then the
sensor will be in a warning state.
Missing Data Intervals(Error/Warn) – Checks the number of missing intervals from
the most recent 100. If too many are missing then it will cause either an error or warn-
ing state based on the thresholds set in the system settings.
Sensor
The Sensor column shows the hostname/IP address on which the sensor is registered, its
port identification and any additional ID information. The entry is formatted as follows: <ip
or hostname>:<port> (<id>). The ID field represents a multi-drop ID for sensors that sup-
port multi-drop communication, or a sensor-specific ID (which is used by the driver). Each
sensor or multi-drop ID is a link to the Sensor Configuration page for that sensor.
Network(s)
The Network column contains the name(s) of the network(s) that the sensor belongs to. A net-
work is an abstract grouping of sensors within Collector used only for convenience in managing
groups of similar data collection devices, groups that are in a certain geographic area or groups
that can be accessed by the same type of user. A sensor can belong to more than one network or
to no network. A Collector network has no bearing on actual sensor functionality. The sensor
itself will function without belonging to a network, and Collector can collect data from that lone
sensor. Networks can be created via the Networks section of the System page (see Chapter 6).
