prometheus-net VS Elasticsearch

You might want to look into prometheus https://github.com/prometheus-net/prometheus-net, https://prometheus.io/.

You would need to build a custom endpoint if it's a custom application that Prometheus can scrape but there are many libraries for that like prom-client for NodeJS or prometheus-net for C#. The list of client libraries can be found here.

You could probably combine a HangFire Job Filter with the Prometheus C# library and log the things you want. Looks pretty extensible.

prometheus-net

I have a websocket server that hoards memory during days, till the point that Kubernetes eventually kills it. We monitor it using prometheous-net.

A library that makes this really easy for us is prometheus-net - we can create a minimal API that exposes metrics quickly and demonstrate a few different ways of creating metric data

// example taken from https://github.com/prometheus-net/prometheus-net#quick-start private static readonly Counter ProcessedJobCount = Metrics .CreateCounter("myapp_jobs_processed_total", "Number of processed jobs."); ... ProcessJob(); ProcessedJobCount.Inc();

You could check out their GitHub and see what is going on https://github.com/elastic/elasticsearch/issues

I believe the 1024 limit has been upped in recent versions of Elasticsearch

https://github.com/elastic/elasticsearch/issues/92458

Elasticsearch is written in Java and its source code is available on Github.

I don't think the murmur3 hash implementation has changed since it was added as the default in version 2.0 (see the [changes](https://github.com/elastic/elasticsearch/commits/main/server/src/main/java/org/elasticsearch/cluster/routing/Murmur3HashFunction.java)). The plugin itself has seen [more changes](https://github.com/elastic/elasticsearch/commits/main/plugins/mapper-murmur3) but that's IMO because of internals and not visible changes in the calculations.

Mysql is not as open source as postgres (long story). And you can see how open elasticsearch is by just having access to the bugs database https://github.com/elastic/elasticsearch/issue
