Description

Grafana can get into a state where it writes more errors messages than it can process. The problem is compounded when Grafana is collecting its own error logs that include the related warnings that it can no longer keep up. This can consume several GB per day of storage.

Mitigation

Modify the following configuration parameters in Grafana: ``` reject_old_samples: false reject_old_samples_max_age: <raise this limit> ```
