Configuring Event Monitor in Fortimanager

Hi Guys,

I m trying to modified the configured event handler for interface down. As we are getting alerts for all interfaces so i though of filtering it by entering some specific text in Generic text box. Also we have ISP configured on wan1 and wan2 interface so i want alerts from that interface only.

I have entered below text in Generic field but now i am not getting any alerts. Please help and suggest.

msg ~ wan1%20was%20turned%20down or msg ~ wan2%20was%20turned%20down
