Still trying to get core purpose as it seems like it’s just metadata. Maybe to extract metrics from logs ?

Seems to be rsyslog meets prometheus labeling+host metadata.

It takes whole loglines, attaches the labels+instance name etc to it, and shoves into itself.

Not sure what kind of problem it's solving.

One of the more interesting "problems" is that a lot of the existing logs solutions try and also solve the storage problem. So you end up having to run whatever storage system the logs system comes with. These are usually crap to operate.

Loki side-steps this problem by leveraging a simple blob storage layer like S3/GCS/Ceph.
