4. Dependencies on other ONAP Components
AAF - the HTTPS certificates are provided by AAF.
AAI - Holmes needs the resource information to perform alarm analysis. Without AAI, the capability of Holmes will be partially unavailable (rules depending on resource information will lose the ability to analyze alarms).
DMaaP - The main input of Holmes. For now, if DMaaP stops work, Holmes could get VES data from nowhere.
OOM - OOM is responsible for the deployment of Holmes. Without OOM, Holmes could also run in a standalone mode, but all OOM/Helm-related functionalities will be lost.
