Undo manually closed problems

[gatekeeper4810]

I made the mistake and closed out some SDWAN health checks and now when a new event occurs the triggered event will not show in problems or dashboard.

is it possible to undo these manually closed problems. Or even better, is it possible to rediscover the items causing a retriggered alert?

*** SOLVED ***

I was able to resolve this issue by going into "Trigger Prototypes" then select the trigger of choice.

I originally had my "Problem Expression" as follows:
last(/Template Net Fortinet FortiGate SNMP/fgVWLHealthCheckLinkState[{#HC_ID}])=1 and (last(/Template Net Fortinet FortiGate SNMP/fgVWLHealthCheckLinkState[{#HC_ID}],#1)<>last(/Template Net Fortinet FortiGate SNMP/fgVWLHealthCheckLinkState[{#HC_ID}],#2))=1

I simply removed a portion to make it as follows:
last(/Template Net Fortinet FortiGate SNMP/fgVWLHealthCheckLinkState[{#HC_ID}])=1

This allowed for the triggers to rediscover items that were previously marked as resolved.

After enough time for discovery I added back the original "Problem Expression"
last(/Template Net Fortinet FortiGate SNMP/fgVWLHealthCheckLinkState[{#HC_ID}])=1 and (last(/Template Net Fortinet FortiGate SNMP/fgVWLHealthCheckLinkState[{#HC_ID}],#1)<>last(/Template Net Fortinet FortiGate SNMP/fgVWLHealthCheckLinkState[{#HC_ID}],#2))=1
