Automatically discover the SNMP/SSH-enabled devices across your network with SeamScanner. SeamScanner's network discovery tool, uses SSH/ SNMP monitoring to quickly create a detailed inventory of your network devices. Once you provide the list of IP addresses, IP range, or subnets, along with SSH/SNMP credentials, SeamScanner will scan through network and create data of same. Use SeamScanner to run a single discovery or schedule discovery jobs that can identify new devices.
A network discovery tool is a type of detection software built to find and help you identify all the devices on your network. The tool uses automatic network discovery to help you better understand what devices are on a local area network (LAN) either through manually running discovery or scheduled jobs. They may also provide the option to monitor those devices for updates moving forward, which can help you visualize the devices in your network and track their performance metric. Network device discovery tool can drill down on specific nodes on your network to see device details, including device information, current node status, average response time, and more. These details can help with troubleshooting specific devices when you encounter an issue in the network.
A network discovery tool works by scanning IP addresses and subnets across your network, typically by using the SNMP/SSH protocol. The SNMP protocol uses UDP polling to identify SNMP-compatible devices, a process with a minimal network performance impact. Since the devices have object identifiers (OIDs) stored on them, the network discovery software can “read” the identifying information to determine the device type. The SSH protocol is used to take terminal access of the system and run commands to get the information.
The basic steps for creating a discovery Workflow on a network device discovery tool include: 1. Choose the IP address ranges for the devices you want to discover. 2. When creating a job, choose the scanning option you want to use to scale your implementation. These include IP ranges, subnets, IP addresses (which can let you scan specific addresses that fall outside of ranges), and Active Directory (which can let you add large subnets). Make sure you have settings that will search for all the device types you want to monitor whether SNMP/SSH-enabled or not. 3. Set your discovery job to either be performed manually or automatically. 4. The device discovery will begin running and can last anywhere from a few minutes to a few hours, depending on the size of your network.
After you run discovery jobs, the network device detection software can automatically import and begin monitoring devices based on the default settings. If you want to be more selective in which devices and nodes are monitored, as well as which applications and interfaces on them are monitored, you can follow a few extra steps: 1. Action workflow In the Inventory, you should see all the discovery Workflow you built in the past. This information is extremely informative for providing an outline of your jobs, when they are scheduled to run. 2. From inventory you can choose which objects you want to add for monitoring. 3. As you go through the inventory, you’ll see the types of nodes discovered, the different interfaces, the specific nodes and devices, and specific elements of the nodes. 4. Once you’ve made all your selections about what you want to monitor with your network discovery software, you can begin the monitoring process. 5. The tool should now automatically monitor all the customized, selected devices.
While there are several benefits of having a network discovery tool, the most important one is its ability to automatically create and update an inventory of the devices on your network. With the rise of BYOD policies, the number of devices on any given network is growing. Network detection tools help ensure you remain aware of all the devices on the network, with the ability to monitor the performance of those devices. Using an automated tool is especially important if you’re dealing with a large or dynamic network with many new devices added or removed on a regular basis. With virtualization and mobile devices, this kind of rapid turnover is common. Automation is also useful if you have devices from multiple vendors, which can otherwise be difficult to identify. A network discovery tool can help you ensure you have an accurate picture of your network.
SeamScanner Network Performance Monitor is built with a network discovery tool to automatically search your network to help discover all the devices and nodes on it. Once those devices are discovered, it will be added into the inventory which can be monitored. Once you create a discovery workflow in Action Workflow, SeamScanner will run the workflow on the specified event or time to discover the SNMP/SSH-enabled devices on your network. SeamScanner creates a detailed network inventory list, which can help users keep track of the devices on the network. From the device inventory list, the tool can create a network map. This map is built to be continuously updated as new devices are discovered. With the network map, you can easily focus on specific nodes and device performance metrics, which is helpful to support your ability to more easily monitor and troubleshoot performance issues your network. You can also customize the map’s appearance and monitoring features as needed. Along with the other features included in SeamScanner, the network discovery tool can help you gain an understanding and help improve the performance of your network.
