Alarm iteration script error

Doug Irwin
over 2 years ago

New to Foglight scripting and new to Groovy.

Been a Foglight admin for some time now and coder for much longer.

INn the script console I've been putting togethor a little something to iterate over all the current alarms. It's WIP and for now just breaks out when it finds a matching alarm then displays some details.

def alarmID
String alarmMessage
String alarmRule
String alarmSource
boolean foundAlarm=false

def alarmService = server.get("AlarmService")
def alarmList = alarmService.getCurrentAlarms()

for (alarm in alarmList) {
	alarmMessage=alarm.getMessage()
	if(alarm && alarmMessage && !alarmMessage.isEmpty()) {
		alarmID=alarm.getID()
		alarmRule=alarm.getRuleName()
		alarmSource=alarm.getSourceName()
		if(alarmRule.contains('Database_Error_Log')) {
			if(alarmMessage.contains('Error: 9414, Severity: 20, State: 1')) {
				foundAlarm=true
				break
			}
		}
	}
}
if(foundAlarm) {
	"Match found\nID: $alarmID Rule: $alarmRule Source: $alarmSource Message: $alarmMessage"
} else {
	"No match found"
}

Now, if I comment out either  of the nested ifs that use contains it all works just fine. But if both are uncommented we get an error and stack thus
