Message | Enter the body of the mail message. For further information about how to obtain the text, see Target Field Configuration below. |
Send SNMP Trap
When you select the Send SNMP Trap notification type, events may be sent in the form of SNMP traps to systems configured to receive such information. For the MIB definition, see the $MZ_HOME/etc/mz_trap_mib.txt file.
Note!
A new SNMP trap format is now available. For backward compatibility purposes, the previous invalid format will still be used by default. However, if you want to use the new format you can add the property
snmp.trap.format.b
to the platform.conf and set it to true to activate the new values.
You can use the topo command to set the property snmp.trap.format.b:
$ mzsh topo set topo://container:<container>/pico:platform/val:config.properties.snmp.trap.format.b true
The value of the agent Address field will be taken from the Container property pico.rcp.server.host .

Configuring the AWS EC2 Access Policy
There are two methods to configure the AWS EC2 as follows:
Add AmazonSNSFullAccess Policy to IAM Role
Access the AWS EC2 instance page and select the IAM Role that you are using in the instance.
AWS EC2 Instance - IAM Role
In the Permissions tab, click the Add permissions drop-down and select Attach policies.
AWS EC2 Instance - Add permissions
Search for AmazonSNSFullAccess to add this permission.
AWS EC2 Instance - Add AmazonSNSFullAccess permission
Creating An Inline Policy to IAM Role
Access the AWS EC2 instance page and select the IAM Role that you are using in the instance.
AWS EC2 Instance - IAM Role
In the Permissions tab, click the Add permissions drop-down and select Create inline policy.
AWS EC2 Instance - Create inline policy
Select the SNS service.

AWS EC2 instance - Actions allowed
Actions allowed - publish
Write - Publish
Effect - Allow
Resources - Specific
topic - Tick Any in this account option
Click Next.
Enter the policy name and click Create policy.
System Log
When you select the System Log notification type, messages produced by the selected events are sent to the standard System Log. The Contents field from each event is used as the message in the log.
Event Notification - Notification Type System Log
Note!
Do not route frequent events to the System Log. Purging a large log might turn into a performance issue. If still doing that, keep the log size at a reasonable level by applying the System Task System Log Cleaner. For further details see System Log Cleaner in Workflow Types.
Target Field Configuration
Some of the notifier types have one or many parameters that may be dynamically populated by data from an event. These parameters are configured in the Target Field Configuration section.
Depending on the parameter type, there will be one or several population types available in the list next to it.
Manual
Select Manual to hard code a value, and thus give no possibility to select any dynamic values to be embedded in the message. The value entered will be assigned to the parameter exactly as typed.
Target Field Configuration - Log Line
Event Field
Select Event Field to assign the value of one specific event field. The event fields for the added events can be viewed in the Event Setup Tab.
For further information about fields valid for selection, see Event Fields.
Event Contents
Select Event Contents to add the event value of each event's Contents field. All event types have suitable event content text. For example, in the figure Events can be customized to suit any target, the Event Contents string will be:
Username: mzadmin3, Action: Notifier AnumberEvents updated.
Another example is that the following string is reported for a User Defined Event:
Workflow name: <name>, Agent name: <name>, Message: <string>
The Message string originates from the dispatchMessage function. Note that nothing will be logged unless dispatchMessage is used. Also, in this case, the Field Maps in the Event Setup will be disabled.
Note!
The same result is achieved when selecting Event Field/strong as Log Line, and then selecting Contents as mapping (the Event Setup tab).
Formatted
Select Formatted to enter text combined with variable names, which are assigned to event field values in the Event Setup Tab tab.
Each variable in Notifier Setup has its own Notifier Field in Event Setup - Send Mail
For each variable entered in a field with the Formatted option selected, a notifier field will be added in the Event Setup tab where you can then assign event field values.
Variable names must be preceded by a $, started with a letter, and be comprised of a sequence of letters, digits, or underscores.
Target Field Configuration - Log Line
The settings in the screenshot above will be interpreted as containing the variables 'NO' and 'ANUM'.
