Can't fetch the logs from loki s3 bucket storage older than 2 hrs

Grafana Loki
1

I am using digitalocean s3 buckets as storage option for logs. I have configured everything same as given on grafana-loki documentation for storing logs to s3 buckets. The files are getting uploaded to s3 buckets also but when I tried to retrive and visualise the logs on grafana dashboard I am only able to see last 2 hrs of logs and not more than that. I am sharing my loki config below

If you don’t see any log older than 2 hours, then either your cluster can’t access the storage bucket while reading, or the chunk files aren’t stored to the bucket correctly. I would check:

  1. First look at the storage bucket and see if chunk files are actually written there.
  2. Check both your ingester and querier logs and see if there is anything there.
