Note
Many sensors do not use all 13 vehicle classes defined by Collector. The subset of
classes used by each sensor may dier by sensor type. Consult sensor driver docu-
mentation for more details about which class numbers are used for data from that
sensor type.
Notifications Tab
e Notications tab allows you to inform system administrators of certain adverse condi-
tions that may occur during regular Collector use (see Figure 7.17). If certain alert condi-
tions are met, Collector will automatically send an email containing the alert details.
Figure 7.17 – Notifications Tab
You can set your own alerts, but only system administrators with the right privileges can
view and edit other users’ notications.
Select a user from the Notications for User list, and the current notication settings (if
any) will be displayed in the controls on the right.
e following are the four primary alerts that can be enabled for user notication:
Queue Size Alert – Informs you that the Collector queue size on a server has exceeded
a certain limit.
CPU Alert – Informs you that the CPU usage for a Collector server has exceeded a
certain percentage.
Memory Alert – Informs you that the system memory usage for a Collector server has
exceeded a certain percentage.
Server Oine Alert – Informs you that a Collector server has gone oine and is no
longer communicating.
