UIM - Alarm configuration for tunnels when they go down

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)
• CA Unified Infrastructure Management On-Premise (Nimsoft / UIM)
• CA Unified Infrastructure Management SaaS (Nimsoft / UIM)

Issue/Introduction

• Alerts are being fired automatically when the tunnel had been down for less than 30 seconds. How can we configure Infrastructure Manager to alert only when a tunnel has been down for at least 5 minutes?
    
  
   

Environment

• Release: UIM 20.x
• Component: UIMHUB

Resolution

In the hub GUI select Tunnels -> Advanced Tab: 'Tunnel is hanging Timeout' and set it to 300 seconds (5 mins).

This setting determines when the tunnel disconnect alarm is generated.

For hubs without a tunnel connection, no alarms will be sent if another hub goes down.

Additional Information

Another way to monitor other hubs is to use the net_connect probe to check if the NimBUS_HUB service (port 48002) is responding.
