Hi, I need to create a custom alarm manager with extended filter capabilities in its own tab in Smart Client.
How can I retrieve the alarm list? I tried to call IAlarmClient.GetAlarmLines from the Init method of a ViewItemWpfUserControl with an alarm client created from AlarmClientManager, but got a System.ServiceModel.FaultException.
I solved it by fetching the alarms in an event server plugin and sending them serialized to the smart client plugin through a communication filter. So it works fine now, but please let me know if I have missed anything and there’s a better way.
You can use this code inside SC …
_alarmClient = _alarmClientManager.GetAlarmClient(EnvironmentManager.Instance.MasterSite.ServerId);
_alarms = _alarmClient.GetAlarmLines(0, maxExport, new VideoOS.Platform.Proxy.Alarm.AlarmFilter()
{
Orders = new OrderBy[]
{
new OrderBy() { Order = Order.Descending, Target = Target.Timestamp }
},
Conditions = new VideoOS.Platform.Proxy.Alarm.Condition[]
{
new VideoOS.Platform.Proxy.Alarm.Condition() { Operator = Operator.GreaterThan, Target = Target.Timestamp, Value = dtStart },
new VideoOS.Platform.Proxy.Alarm.Condition() { Operator = Operator.LessThan, Target = Target.Timestamp, Value = dtEnd }
}
});

This is what I did, unfortunately it causes a FaultException when running in smart client.
Undantagstyp:System.ServiceModel.FaultException

The code I posted is from a SC-only plugin that has been working perfectly for a couple of years, which simply allows you to export all the alarms of a time interval to Excel. It has no ES components.

Im interested in pulling alarm reports as referenced above. Where/how do i utilize the code in SC?
This is my plugin, only in Alarm Workspace …
Click to open this windows … After setting Time Interval the plugin use the code i’ve posted, so it can show how may alarm are present, if you click to Anteprima (Preview) …
If you click on Export button you have to provide name an location of .csv file
