Setting up Alerts
Your Alert appliance has the ability to alert you when a variable reading is in a warning or critical state.
There are two parts to setting up alerts for a particular variable. The first part is to specify at what values is
a particular variable in warning or critical state. The second part is to specify what alert actions should be
taken when a particular variable is in those states.
For example, you can specify that a temperature variable is in critical state if it exceeds 35
o
C, and you may
want your Alert appliance to page or email you when the variable goes into that state.
The two types of variables on Sensorsoft devices and Sensorsoft Plug-in supported devices are scalar and
Boolean. Scalar variables represent qualities such as temperature and humidity. Scalar variables take on
numerical values such as 73
o
F or 25 %RH. Boolean variables represent logical values such as Power
(FAIL/OK), Flooding (WET/DRY), Relay (ON/OFF) and Input Contact (OPEN/CLOSED).
A scalar variable can be in one of 5 possible states:
1. Breach of Critical High Limit
A scalar variable goes into this state when its value becomes greater than or equal to the Critical High
Limit.
2. Breach of Warning High Limit
A scalar variable goes into this state when its value becomes greater than or equal to the Warning High
Limit but less than the Critical High Limit.
3. Breach of Warning Low Limit
A scalar variable goes into this state when its value becomes less than or equal to the Warning Low
Limit.
4. Breach of Critical Low Limit
A scalar variable goes into this state when its value becomes less than or equal to the Critical Low
Limit.
5. Normal
A scalar variable is in this state when its value is less than the Warning High Limit and greater than the
Warning Low limit.
A Boolean variable can be in one of 2 possible states:
1. Breach of Boolean Critical State
A Boolean variable goes into this state when its value is equal to the Boolean Critical Value.
2. Normal
A scalar variable is in this state when its value is not equal to the Boolean Critical Value.
Setting up Alerting Limits for Device Variables
1. Login to the Alert web interface as admin.
2. On the View Monitor List page, click on the Description hyperlink for the monitored device of
interest.
3. On the Device Configuration page, you will see a table that lists information about every variable on
this monitored device. Locate the variable that you would like to set alerting limits for. If the variable
of interest is a scalar variable, then you will need to set the alerting limits in the Critical Low Limit
field, Warning Low Limit field, Warning High Limit field, and Critical High Limit field as shown in
Figure 8. These values should be set in a rising order from Critical Low Limit to Critical High Limit.
