Before resuming StorageGRID operations with the new software version, you must re-enable notifications and make any other configuration changes that are required for the new release.
After the upgrade is complete, you must re-enable system-wide alarm notifications and event-triggered AutoSupport messages. You might also need to make configuration changes to support the new, updated, or removed features in the StorageGRID 11.4 release.
Select Support. Then, in the Alarms (legacy) section of the menu, select Email Setup. For details, see the instructions for monitoring and troubleshooting StorageGRID.

* The metric node_disk_io_time_ms is reported in milliseconds in StorageGRID 11.3. After the upgrade to StorageGRID 11.4, the name changes to node_disk_io_time_seconds_total and values are reported in seconds. To compare values pre-upgrade to values post-upgrade, you must multiply the pre-upgrade values by 1000. |
Because Prometheus metrics data is only preserved for 31 days, the Renamed Metrics dashboard and the Prometheus interface only show historical data for 31 days after the upgrade is complete. After that time, all available data for the updated metrics is shown on the charts and dashboards that use the new names of the metrics.
