Maintenance windows are programmed periods of time where devices with agents installed can be configured to automatically complete tasks for a number of SolarWinds N-central features to a defined schedule.
When running a Hyper-V host/guest, schedule reboots of virtual machines first, then hosts an hour later. This ensures that when including patching maintenance windows, the virtual machines can fully restart before the host reboots.
- Click Views > All Devices.
- Click the name of a device.
- Click the Settings tab, then Maintenance Windows.
- Click Add > Scheduled Reboot.
- Enter a Name.
- Select Allow user to delay the reboot to provide the user with the option to delay the re-start process.
- Select Place device in downtime during reboot to transition the selected devices to a Downtime state while it is being re-started.
- For Force device out of downtime specify the maximum number of minutes the device can remain in downtime before restarting if the agent has not checked in.
- Set a message that appears on the user's screen to inform them that a reboot will occur, to give them time to save their work.
- Set the schedule when the maintenance window occurs.
- Click Save.
This option enables SolarWinds N-central to alert you if the reboot has failed or otherwise taken longer than expected. If the reboot fails, the device will remain in downtime the maximum time that you specify. After the maximum time elapses, the device will come out of downtime and if the agent has not checked in, notifications will be triggered.
This is not a scheduled downtime. This is just a safe-guard for the reboot feature.
SolarWinds N-central saves the reboot maintenance window. At the scheduled time, SolarWinds N-central agents perform the work scheduled reboot.
