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.
I'd consider fapolicyd for untrusted guest account systems. It ensures that only applications installed through the package manager can be run, i.e. no downloads of a local exploit and running ./hack on the terminal.
