A Date Overdue Alert can be generated when a server fails to communicate back to the Dashboard within the allotted time (by default 1.5 Agent cycles). Depending on configuration, this Alert may be sent when there is an issue with the device, but also when it undertook a graceful shutdown. For example, manually or programmatically switched off.
To avoid the generation of a Data Overdue Alert where a graceful shutdown takes place, the Dashboard and Agent may be setup to mark these device as Offline, whilst retaining the Alert generation option if the device remains offline for longer than the threshold figure. For example, a server undergoes a scheduled or managed shutdown and does not come back online.
This setting is available via the Windows Advanced Monitoring Agent and the Dashboard
Windows Advanced Monitoring Agent
- Access the device
- Log into the Advanced Monitoring Agent
- Go to Edit Agent Options > General Settings
- Enable If device is shutdown automatically go OFFLINE
- Click OK to save changes
Dashboard (Windows and Linux)
- Right-click on the Device in the North-pane (or from the Server drop-down)
- Go to Edit Server
- Navigate to General Settings > Offline Mode
- Enable Automatically put the server in offline mode if it is shutdown gracefully
- Set the Maximum Offline Duration: time in minutes before an Alert is sent for an offline server (depending on Alerting behavior)
- Click OK to save and apply
Where a server is reported as Offline it will stay in this state on the Dashboard until the next time data is received.
Do not apply these settings to a constantly running device where any shutdowns are indicative of a problem.
Uninterruptible Power Supply (UPS)
Depending on configuration, computers may undergo a graceful shutdown when the main power supply fails and they are running on a UPS
