How GSX Monitor sends Information using Simple Network Management Protocol (SNMP) Traps

How It Works

SNMP Traps enable an agent (GSX Monitor) to notify the management station (Enterprise Management System) of significant events (alerts) by way of an unsolicited SNMP message. The unsolicited Traps or data packets are sent from the SNMP client to the destination server without being explicitly requested or acknowledged.

Here is a text file containing an example of a SNMP Trap generated by GSX Monitor. 

In the above image, we can see the variables [1] - [14]. The alert message details are in variable [1] the trapVars.trapMessage.0 variable: we can see a disk space alert in the message details. The host name generating the alert is in variable [5] trapVars.resource.0. If an alert profile is configured to send SNMP Traps, GSX Monitor will use some custom variables that are defined in the table below.

Variable	Definition	Type
[1] - trapMessage	Complete trap message	DisplayString
[2] - gsxStationName	GSX Monitor workstation sending the trap	DisplayString
[3] - className	Class of the alert	DisplayString
[4] - alertType	Type of the alert	DisplayString
[5] - resource	Resource in error	DisplayString
[6] - subResource	Sub-resource in error	DisplayString
[7] - status	Status of the resource sending the trap	DisplayString
[8] - severity	Severity of the error	Integer
[9] - date	Date of error detection, using ticks format	DisplayString (ticks)
[10] - alertID	Unique identifier of the alert	DisplayString
[11] - EntityID	Unique internal GSX Monitor installation identifier	DisplayString
[12] - Reminder	(Is this Alert a Reminder)	Boolean
[13] - Escalation	(Is this Alert an Escalation)	Boolean
[14] - Test	(Is this Alert a Test)	Boolean
[15] - Statistics Reset	Resets all open alerts associated with the EntityID	Boolean
[16] - SCOM Severity	The severity level; info, warning, critical.	Integer
[17] - Alert Date	The date the alert is sent	DisplayString

Variable [10] was introduced in GSX Monitor 10.6.
Variables [11 - 17] were introduced in GSX Monitor 10.11.1.
Variable [9] was changed to server tick format in GSX Monitor 10.10.
