Network Device Monitoring Getting Started Guide
This section covers the steps to get up and running with Network Device Monitoring. Setting up Network Discovery (a pre-requisite of Network Device Monitoring), selecting the network device to monitor, managing Checks and devices, configuring the alerting behavior and removing monitoring for a device.
Setup Network Discovery
Network Device Monitoring utilizes Network Discovery to identify those supported devices that are attached to the network as well as run Checks against the devices once selected for monitoring.
Enable Network Discovery Agents
Network Discovery is setup by default, but where it is currently disabled, you will need to enable it at the Client, Site or Device level.
- Network Discovery Settings
- Expand the target Client and Site
- Settings: On
- OK to apply
- Right-click on the device in the north panel (or from the Server or Workstation drop-down)
- Edit Server or Edit Workstation
- Network Discovery
- Settings: On
- OK to apply
Please note, Network Discovery Agents (used to scan the network) are available for Windows devices running Monitoring Agent 9.9.0 RC and later.
Once Network Discovery is enabled and the Network Discovery Agents have installed onto at least one network attached Server or Workstation, you can manage the network via the Networks tab.
- Go to the Networks tab
- Right-click on the target network in the north panel (or from the Networks drop-down)
- Manage selected network and configure the settings.
- OK to confirm
Important: to ensure we can query all the attached devices via SNMP and retrieve details of their monitorable components, please precisely enter all the SNMP credentials are configured to match those in use throughout the network.
Select Network Devices to Monitor
The Checks available for monitorable routers, switches, firewalls and printers depends on whether they respond to our SNMP queries with details of their monitorable components. For those supported devices that do not successfully respond to our SNMP queries, only connectivity monitoring and the Ping Checks are available.
To identify and add monitoring to a supported router, switch, firewall or printer:
- Open the Networks tab
- Choose the managed Network
We have used the following Network Device Monitoring focused columns to easily identify supported devices and the available level of monitoring based on their response to our SNMP queries:
The Device's connectivity using ARP (Address Resolution Protocol). When the device is unreachable it is reported as offline in the Dashboard and an Alert generated (where configured).
The reliability and quality of the Device’s connection to the network Device using multiple ICMP (Internet Control Message Protocol) Echo Requests.
Cartridge Level Check
All ink/toner cartridges on the Device
Paper Level Check
All automatic feed trays on the Device
All physical Ethernet ports on the Device
- Right-click on the target printer, router, switch or firewall (or from Device menu)
- Choose Monitor Device and automatically add the supported Checks for the device.
- This will add the Device to the Network Devices tab on the Dashboard and automatically add the supported Checks for the device.
Please note: monitoring may be available for a Device where we were unable to retrieve its name. When adding monitoring to these Devices, you are prompted to enter a name to identify it in the Dashboard and Alerts.
Once a Device added to monitoring the Network Discovery Agents will run the supported Checks against the selected Device.
You can manage the Checks and setup Alerting for your monitored devices via the Network Devices tab on the Dashboard.
Causes of SNMP Query Failure
A device may fail to respond to our SNMP query where one of the following conditions exists:
- The Device does not support SNMP
- The Device does not support SNMP
- The Device supports SNMP, but SNMP is disabled.
- SNMP is enabled on the device, but it does not support the MIB (Management Information Base) we query for that device type
- The SNMP Community String used by the Device is not in the SNMP Credentials list for the Network
- Network Discovery could not detect the monitoring capabilities of the device
Please refer to the device's documentation for information on its SNMP capabilities and configuration.
Manage Monitored Network Devices
Once under monitoring, the devices appear in the Network Devices section.
Returns the device's current state along with additional information
Devices in the north panel are in one of three states. Hover over the device’s status icon for specific information on its current state.
Green All Checks passed, device is online
Orange Network offline
Red At least one Check has failed and / or the device is unreachable
From the Device's right-click menu, or Device drop-down, you can Edit Device, Run checks now or Remove from Monitoring.
Manage Checks and view their results in the Checks tab, use the Summary tab to display hardware details summary, Check summary and network details.
The amount of hardware details shown for any given device will depend upon the device's SNMP monitoring capabilities. For devices which do not support the required SNMP MIBs, hardware details are not available and will not be shown.
The device’s Checks are managed (Add, Edit, Delete) from its Checks tab.
Add Check button to include additional Checks on the device.
Edit from the device’s right-click menu (or Check drop-down) to amend the monitored components and change the failure thresholds. Where a monitored component includes a threshold option but this is not set, the Check works in report only mode. The component is monitored, but will never report as failed.
Delete from the device’s right-click menu (or Check drop-down) removes the Check from the device
View the Checks status from the last time it ran in the More Information section. Click this link to open the More Information dialog containing additional information on the Check result.
Where a Check is in the failed state it can be marked as cleared (acknowledged) so it does not appear as a failure on the Dashboard.
Email or SMS notifications can be generated when a Check fails and subsequently recovers, and when the device loses connectivity then re-connects.
Network Devices Alerting behavior is configured via:
- Alert Policy
- Network Device Alerts
- Enable or disable the Alert type box against the appropriate Checks or Connectivity setting
- OK to save and apply
To configure the Network Device Alert recipients.
- Alert Settings
- Network Devices
- Choose the target Entity from all Network Devices, down to specific Site
- Enable the required Setting and configure
- OK once complete to save and apply.

Disable Network Device Monitoring
Where monitoring is no longer required for a network device:
- Right-click the target device in the north panel of the Network Devices tab
- Select Remove from Monitoring and confirm when prompted to apply.
Although removed from the Network Devices section, the device remains in Connected Devices under the Networks tab, where monitoring may be re-established at a later date if required.
Please note, when removing a device from monitoring any historical monitoring information is also deleted.
