Algorius Net Viewer Manual | Device Monitoring

General Information

The Algorius Net Viewer scans the devices engaged with all currently opened network maps. The scan is performed according to monitoring configuration defined for the application and for devices. Active and inactive network map devices are shown with different images, which are determined by the device type. You can configure the notification center to additionally display the monitoring results. See Notification for more information.

The device tooltip, which appears when the mouse is hovered over a device, shows additional monitoring results, e.g., ping result or HTTP server error code, etc.

It happens that monitoring requests are lost in the network and don’t reach their destination. This usually happens when the network is overloaded. Algorius Net Viewer can automatically recheck devices if they stop responding in order to eliminate false alarms.

One of the Algorius Net Viewer features is that it uses the asynchronous monitoring technology. This technology ensures maximum efficiency and provides the ability to easily scan hundreds of devices simultaneously with minimum load.

Configuring

To define the monitoring settings, select MonitoringSettings from the main window menu or press the Options button on the toolbar or press F8. The Options dialog box will appear:

The following parameters are available:

  • Refresh rate — refresh rate profiles configuration. In this section you can specify the frequency for each profile. See Refresh rate settings for more information.
  • Thread count — maximum number of devices scanned at a time — a number of simultaneously sent requests. Other requests will wait in line. This limitation minimizes network load and disperses the monitoring in time, which in turn improves the monitoring accuracy.
  • Scanning methods — see Scanning methods for more information.
  • Receive monitoring result from Web server — see Configuring Monitoring Client for more information.

Those devices having notifications assigned are always periodically scanned, regardless of the following monitoring settings: Scan devices periodically, Scan devices on the current map only, Scan only if the application is active. This method guarantees receiving server stop/start notifications in time.

Control

To pause monitoring of all maps, select MonitoringPause All Maps from the main application menu, or Pause All Maps from tray context menu, or press Shift+F4. The corresponding monitoring state will appear in the status bar.

To pause monitoring of the current map, select MonitoringPause Map from the main application menu, or press F4. The corresponding monitoring state will appear in the status bar.

To continue the paused monitoring of all maps, select MonitoringContinue All Maps from the main application menu, or select Continue All Maps from tray context menu, or press Shift+F4. The corresponding monitoring state will appear in the status bar.

To continue the paused monitoring of the current map, select MonitoringContinue Map from the main application menu, or press F4. The corresponding monitoring state will appear in the status bar.

Select MonitoringRefresh All Maps in the main application menu or press Shift+F5 to refresh the monitoring results of all maps without waiting for automatic updates, or when the monitoring is paused.

Select MonitoringRefresh Map in the main application menu or press F5 to refresh the monitoring results of the current maps without waiting for automatic updates, or when the monitoring is paused. Moreover, if some devices are selected on the map, only those devices will be updated. This allows you to quickly update the status of the required devices.

The status bar displays the total number of currently scanned devices or those devices that need to be scanned (i.e. number of scan requests being in the queue).

IP and MAC Gathering

Algorius Net Viewer collects IP and MAC addresses of all scanned devices. The application registers each IP address, which is defined when a device is scanned. MAC addresses are defined by regular ARP Table scan.

IP and MAC addresses are shown in device information dialog box.

There is device search by IP and MAC address available as well.

Application saves the MAC address of devices when closing. This feature allows using devices that where turned off for some time with their MAC addresses not included in the ARP table.

IP and MAC addresses can be used as parameters for external commands. This allows, for example, using the WOL (Wake On LAN) utility for turning on the PC by LAN.
