Hi Deema,

To pass information from the alarm that triggered the correlation rule to an automation script, you can follow the process described in DataMiner Docs: How do I parse Correlation Alarm Info Data.

To mask an alarm, you could use the code available in the following example: https://github.com/SkylineCommunications/SLC-AS-MaskServiceAlarms/blob/main/MaskServiceAlarms_1/MaskServiceAlarms_1.cs

See method AlarmAction.

Hope it helps.

I keep getting this error. I am not sure what I am doing wrong.

The following was returned from the script:
EXIT: "Something went wrong: (Code: 0x80131500) Skyline.DataMiner.Automation.ScriptAbortException: Script parameter 65006 exists, but no value was passed from Correlation.
at Skyline.DataMiner.Automation.Engine.ExitFail(String reason)

using Skyline.DataMiner.Automation;
using Skyline.DataMiner.Net;
using Skyline.DataMiner.Net.Enums;
using Skyline.DataMiner.Net.Messages;

private void RunSafe(IEngine engine)

ScriptParam correlationInfoParam = engine.GetScriptParam(65006);

if (correlationInfoParam == null)
{
engine.ExitFail("Script parameter 65006 does not exist in the Automation script. Please add it as a string parameter.");
return;
}

if (string.IsNullOrWhiteSpace(correlationInfoParam.Value))

engine.ExitFail("Script parameter 65006 exists, but no value was passed from Correlation.");
return;

string alarmInfo = correlationInfoParam.Value;
string[] parts = alarmInfo.Split('|');

string targetRowIndex = "0";

engine.GenerateInformation($"Received alarm - DMA: {dmaID}, Element: {elementID}, Parameter: {parameterID}, IDX: {parameterIdx}, Value: {alarmValue}, RootAlarmID: {rootAlarmID}");

if (parameterID != targetParameterID || parameterIdx != targetRowIndex)
{
engine.ExitSuccess($"Skipped: ParameterID={parameterID}, IDX={parameterIdx}");
return;
}

var connection = engine.GetUserConnection();

AlarmTreeID treeId = new AlarmTreeID(dmaID, elementID, rootAlarmID);

var maskRequest = new SetAlarmStateMessage(
treeId,
AlarmUserStatus.Mask,

connection.HandleMessage(maskRequest);
