Configure and Monitor Network Devices in SCOM
If we talk about Operations Manager capabilities to monitor Network devices, it can monitor physical network routers and switches, including the interfaces and ports on those devices, and the virtual local area networks (VLANs) and Hot Standby Router Protocol (HSRP) groups that they participate in, as well as firewalls and load balancers.
Operations Manager can show you how your network is connected to the computers you are monitoring through the Network Vicinity View dashboard. Using Network Vicinity View, you can see how your topology is laid out, as well as the health of each network device, computer, and the connection between each.
Operations Manager can discover and monitor network devices that use the Simple Network Management Protocol (SNMP) v1, v2c, and v3. For a complete list of supported devices refer below article:
So, let’s start setting up Network Device monitoring in SCOM.
1: Login on to Operations Console and click Administration tab.
2: Expand Network Management and click Discovery Rules.
3: Click on Discover Network Devices under Tasks pane.
4: Provide discovery rule a suitable name.
5: Select the Management Server or Gateway Server from Available Servers list. This server will be used to run the discovery.
6: Click on Create Resource Pool button to create the Network Monitoring Resource Pool.
If you have already created the Network Monitoring Resource Pool, select the Network Monitoring Resource Pool from Available Pools option.
7: Provide Resource Pool a suitable name and click Next.
8: Click on Add button and select the servers you want to add under Network Monitoring Resource Pool.
9: Click Next to continue.
10: Click on Create button to complete the Resource Pool Wizard.
11: Newly created Network Monitoring Resource Pool will reflect under Available Pools, click Next to continue.
12: Choose Explicit discovery option and click Next.
Here we need to select the Run As account for discovery. The credentials in the Run As account enable management servers to communicate with the network devices. You can monitor devices that use SNMP v1, v2, and v3.
Network devices that use SNMP v1 or v2 require a Run As account that specifies a community string, which acts like a password to provide read-only access to the device.
So, will create a Run As account here (Community String) which will also be present in the network device which needs be monitored through SCOM.
13: Click on Create Account button.
14: Provide a suitable name for Run As account and click Next.
15: Provide the Community String and click Create button.
16: Select the Run As account and click Next button.
Now here you need to specify the network devices you want to discover in SCOM.
17: Click on Add button.
Note: If you have a good number of network devices to be discovered, you can save the IP address of those devices in a text file and import the list by selecting Import option.
18: Provide the Name or IP address of the Network Device to be monitored.
19: Select the Run As account and click OK to continue.
20: If you want to add more devices, add them here click Next to continue.
21: Select Run the discovery rule manually option and click Next.
22: Click Create button to create the network discovery rule.
If you get Warning message to distribute the account, select Yes option.
23: Click Close button to close the Discovery Wizard and run the network discovery rule.
24: Right click the Discovery Rule and click Run to run the discovery.
25: The discovered devices will reflect under Network Devices pane.
