The maintenance completion time stated above, is an estimate of the longest case scenario. The actual maintenance period will end once the work has been completed.
After maintenance has begun, the entire Mackerel system will shutdown for a short period of time.
- Web access to Mackerel, data posting by the agent, API access (including the CLI tool), alert notifications, etc. will be unavailable.
As soon as the maintenance work is completed and operation confirmation is obtained, the system suspension will end and an announcement will be made
As for mackerel-agent metric posting, data will be buffered from mackerel-agent during the maintenance period and resent after maintenance has been completed
- If resent correctly, graphs during the maintenance period will also be displayed.
- Please be aware that restarting / stopping the mackerel-agent before retransmission has been completed will result in the loss of buffering data.
- Launching mackerel-agent during the maintenance period will fail because communicating with the Mackerel system will be unavailable.
