Ask HN: What metrics stack are you using for side projects

After having worked with a nice metrics stack in my worklife. I feel kind of blind in my side projects. What are all y'all using for metrics and visualization for your side projects? I'd prefer a SaaS solution, and I'd love to be able to (easily): - Publish (time-series) metrics from my code - Create dashboards visualizing these metrics - (Optional) setup alerting on these metrics

The stacks I've been able to find are either very tied to Prometheus, or tracing. I would like to emit more metrics semantically more close to the application. Examples: - Backlog size - Concurrent items being processed - Number of items in a specific state

So what are you running in your projects, where it would be overkill to run your own prometheus/grafana/influx/whatevs stack?
