You can change it in Grafana in the datasource section of Loki.

If you use logcli it's a simple flag. If you use the API it's a query string limits.

Hope this helps.

thanks，I have solved it. But if you set more than 5000 lines。The log query page will report an error。

@yangvipguang You can change the max_entries_limit_per_query value in Loki's limits_config

Ok,I think so. But before I do't find the setting in the limits_config configuration of document. I will try. Thanks

I'm a bit confused about this:
the default value of max_entries_limit_per_query is 5000 as documented here https://grafana.com/docs/loki/latest/configuration/#limits_config,

but why I still get 1000 limit in grafana explore?

^ ah I found it in datasource settings.

max_entries_limit_per_query

Could you share your knowledge as to how you found the datasource settings.
And also how you edited it to change the limit. So others finding this thread in the future may directly see your findings.

^ change the max lines above

Regardless of what value i set for max_entries_limit_per_query in values.yaml, i see that loki pod always defaults it to 5000. I tried with new installation, with upgrades, etc, it still defaults to 5000.

@yongzhang the configuration to increase max lines for loki datasource will be like below
https://grafana.com/docs/grafana/latest/datasources/loki/

datasources:
  - name: Loki
    type: loki
    access: proxy
    url: http://localhost:3100
    basicAuth: true
    basicAuthUser: my_user
    jsonData:
      maxLines: 1000
      derivedFields:

Me, too. How did you solve this problem?

To increase the maximum number of entries returned per query in Grafana when using Loki, you'll need to modify the max_entries_limit_per_query parameter in your Loki configuration file (loki-config.yaml or similar).

By default, this value is set to 5000, which means any query in Grafana will only return up to 5,000 log entries unless specified otherwise. To raise this limit, you can set it up to a maximum of 50000.

Here’s how to update your Loki config:

limits_config:
  max_entries_limit_per_query: 50000

Make sure this setting is under the limits_config section. After updating the config file, restart your Loki instance to apply the changes.

For more details, you can refer to the official Loki configuration documentation:

Let me know if you'd like help formatting the config file or troubleshooting the change.
