Infra monitoring - InfluxDB3 vs Prometheus

InfluxDB 3
1

Hello everyone!

I am currently using InfluxDB Cloud, and in the process of migrating to Core. One of my goals will be infra monitoring, and I see online that many people use a combo of Influx and Prometheus. I am wondering if InfluxDB3 Core alone could do the job, but I cannot find resources that answer this question in the current state of things (June 2025).
Questions for the more experienced users, what would be the added value of Prometheus? Are there downsides to skipping it?
Is anyone running InfluxDB-only infra monitoring in production? And if so, how do you manage alerting?

Thanks a lot for your help!

Yes, you can confidentially migrate from Prometheus to InfluxDB 3 Core for infrastructure monitoring, many users & customers have successfully. Regarding alerting you can leverage the ready to use Processing Engine plugins to set alerts, notification, sms etc easily Alerting with InfluxDB 3 Core and Enterprise | InfluxData. Btw you can also use Telegraf plugin offers to ingest Prometheus data into InfluxDB for migration purpose etc.
