Ask HN: How do you deal with application logging in a web service?

I work for a large company that has an internal logging environment and I'm trying to figure out what the external equivalent is. Basically, I want to add logging statements throughout my app, I want those statements to get pushed to some external store and I want to query that store later (ideally using a UI but SQL might work as well). I would like access to that store within minutes and I doubt the amount of data will be significant at least for now. I'm building a python (flask) app if that changes anything.

The solutions I've considered are DataDog and AppDynamics but they seem to focus on the server health instead of the application logs which is what I want.

I would prefer not to build my own solution here. Is this a solved problem?

Datadog can definitely ingest application logs (you can send any tail any log file and send it to DD).

We used to push application logs to https://logentries.com/ "With our free plan you can send up to 5 GB of data per month and store the last 7 days of data. The free product is available at the end of your unlimited 30 day trial."
https://www.splunk.com/ allows 500MB/day free.
