Meaning #

The ThanosReceiveConfigReloadFailure alert is triggered when a Thanos Receive component fails to reload its hashring configurations. This is indicated by the metric thanos_receive_config_last_reload_successful being 0 for a certain job. This alert is critical because it may lead to data inconsistencies and errors in the system.

Impact #

The impact of this alert is that the Thanos Receive component will not be able to function properly, leading to:

  • Data inconsistencies and errors
  • Potential data loss
  • Inaccurate query results
  • Downtime of the system

Diagnosis #

To diagnose the issue, follow these steps:

  1. Check the Thanos Receive component logs for errors related to config reloading.
  2. Verify that the hashring configuration is correct and up-to-date.
  3. Check the network connectivity and permissions to ensure that the Thanos Receive component can access the hashring configuration.
  4. Verify that the Thanos Receive component is running with the correct configuration and flags.

Mitigation #

To mitigate this issue, follow these steps:

  1. Check the Thanos Receive component configuration and update it if necessary.
  2. Restart the Thanos Receive component to trigger a config reload.
  3. Verify that the hashring configuration is correct and up-to-date.
  4. If the issue persists, contact theThanos administrator or a senior engineer for further assistance.
