This is the error I am getting…But its uploaded one file with name loki_cluster_seed.json and with the contents

{"UID":"246af642-19c5-4dd7-9e41-a30155126a0a","created_at":"2024-09-10T10:50:31.869013055+05:30","version":{"version":"2.9.10","revision":"7664eda07b","branch":"HEAD","buildUser":"root@98f97496e533","buildDate":"2024-08-09T18:28:28Z","goVersion":"go1.22.5"}}

And my loki config file is

It automatically uploads that json file but gives an error…What might be the issue!

The seed file is for the analytics collection by Grafana (see Grafana Loki configuration parameters | Grafana Loki documentation). If you accidentally deleted it then it’ll error but doesn’t actually break anything. You can either ignore it, or disable analytics to not create the file.

What are the changes need to do to store the logs to my AWS s3 bucket…I refer the documentation also and configured exact what it has in the documentation but its not stored the logs to s3.Can you suggest the loki config file to store the logs to s3.

There are examples here: Storage | Grafana Loki documentation

Essentially you want to:

  1. Specify a storage configuration for AWS S3.
  2. Reference that AWS S3 storage from your index schema configuration.
