The restarts dashboard shows a list of domain and device restarts and reloads.
DPOD classifies the restarts into 5 categories:
- Device Initiated - restarts initiated by the DataPower due to a reason (e.g. low memory)
- User Initiated - a restart that was initiated by a user via the web interface, CLI, etc.
- First Boot - the first startup of the device
- Unexpected - for example, due to a power failure
- Domain Restart - a user initiated domain restart
DPOD analyzes the restarts by reading the monitored device's audit logs every 15 minutes, you can change this interval through the Web Console by navigating to Manage→System Parameters→Interval in Seconds to Analyze Audit Logs.
The Restarts Dashboard contains 4 parts:
- A graph showing the restarts over a timeline
- The Device memory graph (a device initiated restart is often related to memory issues)
- Device and domain restarts table
Last sample time table
Restarts Timeline
The chart shows all the restarts on a timeline.
Zoom over a specific part of the graph to apply the time period as a filter.
Click on the restart cause (Device Initiated, User Initiated, etc.) in the legend to reload the page with this restart cause as a filter.
Device and Domain Restarts Table
The table shows all the restarts in a chronological order.
It may suggest that one of the devices is currently experiencing downtime.
Check the "Last sampling time" table at the bottom of the page for more information.
| Column | Description |
|---|---|
| Device | The monitored device name |
| Domain | Populated only for Domain restarts |
| Down Time | Contains the timestamp of the audit log record that preceded the restart message For "Unexpected Restart" the Down Time figure is an estimation, |
| Up Time | Contains the timestamp of the audit log record that signaled that the device was started |
| Est. Duration | The downtime duration (rounded) |
| Cause | Device Initiated, User Initiated, Unexpected or Domain Restart. |
| Type | Either "Firmware Reload" or "Device Restart" |
| Reason | Populated only for "Device Initiated" restarts |
| Firmware | The firmware version |
Last Sampling Time and Sampling Errors Table
This table shows the last time DPOD readi and analyzed the audit logs for each monitored device
| Column | Description |
|---|---|
| Device | The monitored device name |
| Last Sample Time | The last time DPOD accessed the device audit logs |
| Last Analyze Time | The last time DPOD analyzed the audit logs |
| Errors | Lists any errors that occurred, e.g. "Could not connect to host" |
