The restarts dashboard shows a list of domain and device restarts and reloads.

DPOD classifies the restarts into 5 categories:

  1. Device Initiated - restarts initiated by the DataPower due to a reason (e.g. low memory)
  2. User Initiated - a restart that was initiated by a user via the web interface, CLI, etc.
  3. First Boot - the first startup of the device (the restart count is 1)
  4. Unexpected - for example, due to a power failure
  5. 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:

  1. A graph showing the restarts over a timeline
  2. The Device memory graph (a device initiated restart is often related to memory issues)
  3. Device and domain restarts table

  4. 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.

When one of the devices was not sampled or analyzed, an error message will appear in the table's header alongside the title.
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.


ColumnDescription
DeviceThe monitored device name
DomainPopulated 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,
Since the DataPower logs will not contain any shutdown message, DPOD will try to use the last time it received Resource Monitoring data from the device.

Up TimeContains 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.
Hover over the cell to get more information about the user who initiated the restart

TypeEither "Firmware Reload" or "Device Restart"
ReasonPopulated only for "Device Initiated" restarts
Firmware

The firmware version
Hover over the cell to get more information about the IDG version and build information

Last Sampling Time and Sampling Errors Table

This table shows the last time DPOD readi and analyzed the audit logs for each monitored device

ColumnDescription
DeviceThe monitored device name
Last Sample TimeThe last time DPOD accessed the device audit logs
Last Analyze TimeThe last time DPOD analyzed the audit logs
Errors

Lists any errors that occurred, e.g. "Could not connect to host"
