Advice on how I could model this graph database

Suppose I have 100s of millions of data that basically consists of values calculated from several different services. This data may represent transaction from service 1 to service 2, date-time, anomaly score, errors, hits and so on. Now representing these services in nodes and relations are understandable but how will this graph model update its scores and metrics in a timely manner say every 3 minutes. How can I model this graph? Also, assume that I have this data already stored in ElasticSearch. Hope I am clear (if not, I can be more articulate). Thanks in advance.
