Previous pageReturn to chapter overviewNext page

Each event that occurs in Nx Witness is stored in the Event Log. Event logs make it easy to navigate through past activity and diagnose device or server issues.

To view the Event Log

Open Main Menu –> System Administration (shortcut Ctrl+Alt+A) –> General tab and click on the Event Log button

Click on the Event Log icon log_hovered in the header of the Notification Panel

To sort the Event Log

Events are displayed in the following columns. You can click on any column header to sort the log in ascending or descending order:

Date/Time – date and time the event occurred

Event – the type of event

Source – the resource that initiates the event: device (motion detection, input signal, etc) or server (storage failure, server failure, etc).

Action – the action that is performed when the event occurs.

Target – the Users or Devices that are recipient of the action.

Description – any additional information. For motion detection events, the description includes a hyperlink that will open the device in a new layout and start playback of the event.

To filter the Event Log using the header menus

Start date and End date – select a day in each of these calendar fields to show only events that occurred during a particular time period. Default display is the current day. Dates are shown in dd/mm/yyyy format.

Event type – from the pulldown menu, select an event category (Any Event, Any Device Issue, Any Server Issue, Analytics Event, Generic Event), or specific type of event within those categories.

Device type – display events occurring on a particular device only (applies to Motion, Input and Device Issues).

Action – display only the events caused by a particular action.

Click the Clear Filter button to remove all filter conditions. Click the Refresh button to apply additional filter criteria to list that is already filtered.

To filter the Event Log using event fields

You can also use the context menu of a log field to filter the display according to that field's value. For example, if you right-click in the Source field of a specific event and choose Filter Similar Rows, only the events occurring on the same source will be displayed. Similarly, if several filter criteria are in effect, you can remove a single filter criteria by opening the context menu for the desired field (Date/Time, Event, Source, etc.) and choosing Clear Filter to display all values for that field.

To view the Event Log for a specific device or server

Device – open the device context menu and select Check {device type} Issues

Server – open the server context menu and select Server Diagnostics

Other Event Log actions

Context menus in the Event Log provide different functions, depending on the field (event, source, action, etc.) from which they are opened. The following functions are available from the context menu for all fields:

Select All (shortcut Ctrl+A) – selects all entries in the log

Export Selection to File – save the selected data to an HTML or CSV text file.

Copy Selection to clipboard

Context menus in the Source field provide several additional functions, depending on the device.

You can drag the mouse or use Ctrl+Click or Shift+Click to select multiple and apply actions to multiple events.
