The restarts dashboard shows a list of domain and device restarts and reloads.
DPOD classifies the restarts into 4 categories:
- Device Initiated - restarts initiated by the DataPower due to a reason (like low memory)
- User Initiated - a restart that was initiated by a user via the web interface, CLI, etc.
- 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 from Manage→System Parameters→Interval in Seconds to Analyze Audit Logs
The dashboard consists of 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 reload the page with this 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 |
| 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
The table shows when was the last time DPOD was reading and analyzing 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 error occured - for example, "Could not connect to host" |
