Nice article but is it deliberate that you don't mention getting data into the database (line protocol or similar) or analysing the results and displaying them.

Input = use postGres Output = Grafana has a postGres data source which I assume works and mention in timescales b's issues of a Grafana query helper.

Also lack of analysis, consolidation (continuous queries) and retention policies.

I am however intrigued as it does seem to hit my sweet spot of 100's of servers each with 5 to 10 different series of 10 metrics each, every 10 sec.

Database size might be an issue, as would the complexity of deployment (a big win for Prometheus rather than influxdb though).

Final thoughts Can't help feeling this looks like a few input scripts running on postGres rather than a system solution for metrics and annotations.
