cortex VS VictoriaMetrics

Official Product Page: Cortex Metrics

Cortex is a horizontally scalable, highly available, multi-tenant prometheus alternative.

There are many Projects like Thanos, M3, Cortex, and Victoriametrics. But Thanos is the most popular among these. Thanos addresses these issues with Prometheus and is the ideal solution for scaling Prometheus in environments with extensive metrics or multiple clusters where we require a global view of historical metrics. In this blog, we will explore the components of Thanos and will try to simplify its architecture by building it step by step, starting with the main components. We will also have a demo using k6-metrics. Before diving into Thanos, I recommend reading our blog on Prometheus Monitoring with Prometheus if you are not already familiar with Prometheus.

now if its more metric data you are using and want to do APM, prometheus is your man https://prometheus.io/, want to make prometheus your full time job? deploy cortex https://cortexmetrics.io/, honorable mention in the metrics space, Zabbix, https://www.zabbix.com/ I've seen use cases of zabbix going way beyond its intended use its a fantastic tool

Yes, but also no. The Prometheus ecosystem already has two FOSS time-series databases that are complementary to Prometheus itself. Thanos and Mimir. Not to mention M3db, developed at Uber, and Cortex, then ancestor of Mimir. There's a bunch of others I won't mention as it would take too long.

You can use the Remote write feature to send to a centralized location. It would have to be scalable like Cortex https://cortexmetrics.io/

Cortex is not really good for high-cardinality metrics (if you are talking about https://github.com/cortexproject/cortex)

For a homelab I think prometheus + grafana is easy to get started and scales well. There are lots of ways to set up the architecture. Prometheus can write to a directory on a filesystem, it can be set to write to a remote server, and there are other projects to integrate object storage (s3, minio, etc) or influxdb for long term storage and downsampling.

Cortex (it is renamed to Mimir recently).

Wait, I see it's been removed actually [1]. Why, isn't it faster anymore?

Thanks! If you'll hit any issues with the integration, then please file them at https://github.com/VictoriaMetrics/VictoriaMetrics/issues , so we could quickly resolve them.

Yup, there is a big room for improvements there! BTW, VictoriaLogs docs are open source too [1], so we'll be more than happy receiving pull requests with improvements for the docs!
