InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
take a look at https://www.sexilog.fr/ , its a free preconfigured ova based of the elk stack, with preconfigured filters for vmware. I agree wit the other comment doing it with powercli seems inefficent, if you can't buy loginsight, at least install something like this for free.
