Software Benefits for Flood Forecast & Alarming. The AlarmManager.
AlarmManager
Water Resources Management
The WISKI Alarm Manager is a complete alarming system that can be configured monitor thresholds for any parameter measured in the WISKI database, including Stage and Flow thresholds, changes over time of given values, as well as any water quality parameter you collect.
Alarm handling
The AlarmManager offers two types of alarm handling.
Case 1:
SODA calls the stations to get measurements values “station poll”
The data are converted into a ZRXP format
The AlarmManager imports the data and classifies it regarding to the alarm levels
If the configured threshold values are exceeded, the message distributor sends alarm messages to the recipients
Case 2:
An external system sends an event message in XML
The AlarmManager imports the message and classifies it regarding to the reported status
If there is a reaction for this status the message distributor sends alarm messages to the recipients
Importing event messages
The AlarmManager imports event messages from several sources. The interfaces between the external systems and the AlarmManager are directories that are watched by the AlarmManager via FTP import services. Each type of source has its own associated parser. With this modular system it is easy to enhance the import system with new event sources. Current event sources include:
Dial in / data polling from station
Observer messages
Event messages from the SODA logger poll
Results from the WISKI calculation server
SDS (System Diagnostic Service)
External systems
Classification
AlarmManager offers two classification types for incoming events. When it concerns information about time series values, the application checks if the value exceeds the threshold value of the associated station. If it does exceed the threshold value, AlarmManager appoints the proper alarm status to the time series. Event messages without time series values are classified by event types. The event type is defined by the transmitter and the media type by the event message.
Reactions
It is possible to configure single reactions that are based on the classification of an event. A reaction describes which recipients or recipient groups should get an alarm message when a specific type of event messages is received or when the alarm state of a time series changes.
Basic data and alert phases
Templates
The messages that are sent to the recipients can be preconfigured in templates. All important variables relating to the event, such as station number, parameter, measured value, threshold, and the time of the event, will then be automatically inserted into the appropriate place in the template. The user can create the templates with Microsoft Word and store them as XML files. AlarmManager is capable of accessing the locally edited templates via its own interface.
Recipients
A weekly calendar can be configured for each recipient, which specifies when this recipient is available and which communication pathways can be used to access it. Therefore it is possible to e-mail the user during working hours and, in addition to that, to send a text message during his standby period after work or during the weekend. A selection of receivers can be grouped so that a large number of groups can be notified in the event of an alarm. In addition to configuration with the weekly calendar, the standby service can be configured with an annual calendar.
Remote call system SODA
A special form of recipient is the remote call system SODA. The incoming event then triggers a preconfigured remote call a “task” in SODA. For example, this can be used where a precipitation event at one measurement site will lead to the whole catchment area being polled.
Monitoring
AlarmManager allows you to comprehend the processing of incoming event messages due to a powerful monitor. Additionally the AlarmManager stores information about all user and server actions in the application log. This way detailed information about all activities running in the AlarmManager is madeavailable.
