Introduction

Starting with release 2011.02, a task for the MC_SytemAlerter workflow can be configured to send an alert to the Alarmmodule, developed by Imtech for the IWP system. The alert sending has been implemented as an invocation of the Alarmmodule via a SOAP call (also know as a Webservice call). This page how to describe the FEWS-related part of the implementation.

Currently these tasks can only be scheduled using the "Upload task(s) from file" functionality in the Admin interface. The uploaded XML configuratio should conform to the taskList.xsd schema. For examples see below. The Alarmmodule alert part is defined in the referenced mcSystemAlerter.xsd schema.

Schedule fixed alert

In the fixed alert scenario, the alert is entered as part of the taskproperties of the scheduled MC_SystemAlerter task. This can be used to send regular or one-off alerts and will probably mostly be used for testing purposes.

Schedule template alert

The alert with the template is intended to be used as a suspended task which can be triggered through event-action configurations to trigger a single task, in that case, the log messages triggering the alert will be added to the task, if in the template, the following tags are used:

  • %LOG% will be replaced by the message part of log entry
  • %EVENT_CODE% will be replaced by the event code of the log entry
  • %MC_ID% will be replaced by the MasterController ID creating the alert.
