Alarm statuses

[paulcsiki]

Hi everyone,


I'm trying to create an application that notifies me whenever a vCenter alarm gets triggered however I keep getting a gray value for the OverallStatus field of the AlarmState object for that particular alarm. I see 4 triggered alarms in the vSphere Management Console but the API reports all alarms as not triggered.


This is my C# code:

List < Alarm > list = new List < Alarm > ();

ManagedObjectReference mgr = serviceContent.alarmManager;

AlarmState[] alarmStates = null;

foreach(ManagedObjectReference reference in alarmReferences) {

AlarmInfo info = (AlarmInfo) GetPropertiesAsync(reference, new[] {

"info"

})[0];

if (info == null) continue;

if (alarmStates == null) {

var asyncResult = service.BeginGetAlarmState(mgr, info.entity, null, null);

asyncResult.AsyncWaitHandle.WaitOne();

alarmStates = service.EndGetAlarmState(asyncResult);

}

AlarmState state = LookupAlarmState(info.alarm, alarmStates);

if (state == null) {

var asyncResult = service.BeginGetAlarmState(mgr, info.entity, null, null);

asyncResult.AsyncWaitHandle.WaitOne();

AlarmState[] newStates = service.EndGetAlarmState(asyncResult);

if (newStates != null && newStates.Length > 0) {

alarmStates = alarmStates.Concat(newStates).Distinct().ToArray();

state = LookupAlarmState(info.alarm, alarmStates, true);

}

if (state == null) continue; // we don't add alarms that don't have states

}

Alarm alarm = new Alarm(info.alarm.Value, info.name, info.alarm, info, state, info.description, info.enabled);

if (filterFunc(alarm)) list.Add(alarm);

}

return list;

private static AlarmState LookupAlarmState(ManagedObjectReference alarmMor, IEnumerable < AlarmState > alarmStates, bool reverse = false) {

if (alarmStates == null || alarmMor == null) return null;

if (reverse) alarmStates = alarmStates.Reverse();

return alarmStates.Where(state = > state != null).FirstOrDefault(state = > state.alarm.Value == alarmMor.Value);

}

 


Also I've tried to get the Alarm via PowerCLI:


Get-VMHost | Select-Object TriggeredAlarmState


And again no alarms were returned. What am I doing wrong?


Thank You,


Paul
