Configuring Data Alarm Equations
The equation is the heart of any data event. The following are a few examples event equations:

alarm_code = "L31"

ext >= "A 600" AND exit_code = "DN"

(alarm_code > "1051" OR exit_code = "1Ow74x") AND switch = " 001.1.9*.**"

@ = "CRITICAL"
Here are a few tips to help you create your own data event equations:

Multiple field references are acceptable, as long as both fields are the same length. For example,
d=c
is a valid
equation if the fields that both 'd' and 'c' represent are two characters long

Variable names are case sensitive

Equation literals (the data contained within quotation marks) are case sensitive

If any rule is violated in a equation, an alarm will not be generated, nor will an error be presented
Note: There may be times when two or more fields are necessary to analyze one piece of data. For example, if a
time is represented in hh:mm format, some calculations may require two different fields. Other times, wildcards will do
the job of masking out non-important characters just fine.
The data alarm equations used in the T850 are standard Boolean-type operators. The following table outlines each of
the supported operators and their function.
Operator Function
> Greater Than
< Less Than
>= Greater Than or Equal to
<= Less Than or Equal to
! or <> Not Equal to
= Equal to
* Single character wildcard (matches any character or space)
() Parenthesis used to combine operations
OR Logical OR
AND Logical AND
@ Positional wildcard (used in place of a field name to match anywhere within an
incoming record)
