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.
A bit more than you're asking for, but I run Lynis and follow (most of) the suggestions. It won't directly tell you what packages are vulnerable, but it will tell you if automatic security updates are set up.

The number of mentions on this list indicates mentions on common posts plus user suggested alternatives.
