Types of Alarm Notices
When alarms are detected by the S530 and a notification event is warranted, you have a choice of number of different
alarm methods. Specifically these are:
•
•
•
•
(requires EDGE wireless modem)
•
(requires dialup modem)
The following section describes these messages and how to use them.
SNMP Traps
SNMP Traps are alarm notices which are sent using TCP/IP and which conform to the requirements of the SNMP
protocol. In essence, the SNMP Trap is a TCP/IP alarm message using the SNMP protocol, which contains a number
of name/value pairs in its payload. In this payload the “name” is an SNMP Object ID and the “value” is the value of
that OID.
In the case of the S530 product, there are two defined SNMP traps that you can choose from. These traps are
defined in the SNMP MIB, which is provided with the S530 product (or which is available through the Asentria website
or
The first trap is a ‘Standard’ SNMP trap. This is the original SNMP trap format supported by Asentria products. In this
trap there are two name/value pairs in the trap payload;
‘siteName’
which is the sitename of the device sending the
trap and
‘stockTrapString’
which is a string value, which is the standard concatenated alarm message string
used for this and other alarms messages in the S530.
The stockTrapString message format looks like this:
Date Time :: SiteName :: Sensor Pod/Bank name :: Sensor Point Name :: Alarm Alias
For example, the stockTrapString might actually look like this
10/24 06:43 :: San Diego Site #12 :: Sensor Pod 12 :: Cabinet Temp :: Temperature Very High
For users familiar with SNMP, the actual SNMP MIB definintion of the Standard SNMP looks like this:
S530StockTempTrap TRAP-TYPE
ENTERPRISE S530
VARIABLES { siteName, stockTrapString }
DESCRIPTION
"A stock temperature trap is issued when a temperature event
happens."
::= 120
The other kind of SNMP trap which you can use what we call a ‘User Defined Trap’. In this trap we provide for a
series of traps which each have an individual “Trap number”. This can be easier to integrate with management
systems because the manager can have rules setup to kick in when you get “trap # 1000” or “trap # 1001” on. When
using User Defined Traps, the trap number to use is assigned as part of the Event Definition Setup. In the case of
User Defined Traps, the payload of the trap contains a number of OID variables, essentially anything that might be
relevant to the particular alarm being transmitted. If the variable is not relevant for the alarm being transmitted then
that variable is null.
For users familiar with SNMP, the actual trap definintion in the SNMP MIB looks like this:
