32 Import Status Checker

This predefined module is created to write log messages when the import status of data feeds did not receive any new data for a certain amount of time.

It can be configured as predefined activity in a workflow file: 

	<activity>
		<predefinedActivity>import status checker</predefinedActivity>
	</activity>

It is using the <defaultTimeThreshold> and/or <extraTimeThreshold> configuration from the display config file SystemMonitorDisplay.xml, just like the Import Status tab.

Two new elements need to be added to the <timeThreshold? element; an <eventCode> and a <logLevel>. 

When th import status checker is configured in a workflow but the SystemMonitorDisplay.xml is not available in the config, Delft-FEWS will log an Error.

		<extraTimeThreshold>
			<dataFeedId>ImportScalar</dataFeedId>
			<timeThreshold>
				<periodLength value="12" unit="hour"/>
				<color>yellow</color>
				<eventCode>DataFeed.missing</eventCode>
				<logLevel>INFO</logLevel>
			</timeThreshold>
			<timeThreshold>
				<periodLength value="24" unit="hour"/>
				<color>orange</color>
				<eventCode>DataFeed.missing</eventCode>
				<logLevel>WARN</logLevel>
			</timeThreshold>
			<timeThreshold>
				<periodLength value="36" unit="hour"/>
				<color>red</color>
				<eventCode>DataFeed.missing</eventCode>
				<logLevel>ERROR</logLevel>
			</timeThreshold>
		</extraTimeThreshold>

When a data feed did not receive any new data longer than the period length, it will log a message with the <logLevel> and <eventCode>.

Since Delft-FEWS 2025.02 a <graceTime> element can be added to the <timeThreshold> element. The grace time is used to log a message only once in the configured period. This functionality is usefull when the Import Status Checker runs very frequently, but you do not want a log message each time it finds the same datafeed not to be updated.

		<timeThreshold>
			<periodLength value="5" unit="minute"/>
			<color>yellow</color>
			<eventCode>ImportStatus.missing</eventCode>
			<logLevel>ERROR</logLevel>
			<graceTime unit="hour" multiplier="6"/>
		</timeThreshold>
