The alerts API can be called and will give you a list of alerts, you can then filter out what you want in Powershell or another language... : https://vrops.vman.ch/suite-api/api/alerts?pageSize=5000
(see screenshot)
From there you obtain the alert ID: <ops:alertId>2b09d8ea-f0fa-4a23-a73a-81c7764c7649</ops:alertId>
or the link to the specific alert in vRops API /suite-api/api/alerts/2b09d8ea-f0fa-4a23-a73a-81c7764c7649
or to the Resource that threw the alert /suite-api/api/resources/9e3e56f8-33f0-4c34-a882-d49dca948378
Once you have the value 2b09d8ea-f0fa-4a23-a73a-81c7764c7649 just build the URL to the alert in the GUI : https://vrops.vman.ch/ui/index.action#/alert/2b09d8ea-f0fa-4a23-a73a-81c7764c7649/summary
Hope that helps...
