This article shows how to setup this script as an alert action. Please take time to review the main overview article if you have not already done so: Slack Alert Integration - Overview . The main overview article contains information necessary to completely setup this script.
This script is specifically designed for node based alerts.

In the Trigger Actions I added 'Execute an External Program' action.

This is the full text in the 'Network path to external program' field.
- C:\windows\system32\windowspowershell\v1.0\powershell.exe -ExecutionPolicy unrestricted -command "<C:\path\to\script>\Slack_Alert_Trigger_Action_Node_Packet_Loss.ps1 '${N=SwisEntity;M=DisplayName}' '${N=SwisEntity;M=Stats.PercentLoss}' '${N=SwisEntity;M=PercentLossThreshold.IsLevel1State}' '${N=SwisEntity;M=PercentLossThreshold.IsLevel2State}' '${N=Alerting;M=AlertDetailsUrl}' '${N=SwisEntity;M=DetailsUrl}' '${N=Alerting;M=AcknowledgeUrl}' '${N=Generic;M=DateTime;F=OriginalValue}'"
**You will need to update the <C:\path\to\script> in the above line to the location that you have the script saved.**
I'm passing in the following Orion variables:
- Node Name: ${N=SwisEntity;M=DisplayName}
- Node Response Time: ${N=SwisEntity;M=Stats.ResponseTime}
- Packet Loss Warning Value Reached: ${N=SwisEntity;M=PacketLossThreshold.IsLevel1State}
- Packet Loss Critical Value Reached: ${N=SwisEntity;M=PacketLossThreshold.IsLevel2State
- Alert Details Page: ${N=Alerting;M=AlertDetailsUrl}
- Node Details Page:${N=SwisEntity;M=DetailsUrl}
- Auto Acknowledge URL: ${N=Alerting;M=AcknowledgeUrl}
- Orion Date/Time: ${N=Generic;M=DateTime;F=OriginalValue}
Once that alert action is completed then copy it to Reset Actions. Finish editing the alert and you should be done.
