SNMP is an effective way to monitor the health of network devices that you cannot monitor with a Server Agent. Our OnSight vCollector enables you to collect SNMP metrics in your account alongside your other monitoring like server health, application metrics, and network uptime and availability.

Create an SNMP credential
To create an SNMP credential, perform the following steps:
- Select Settings > Credentials from the main navigation header.
- On the Credential Management page, select + Add SNMP Credential.
There are a few different variables to fill in, such as the SNMP Label, which is the user-friendly reference to the credential. You’ll use this when you are adding the credential to devices in the Panopta control panel. You also have to choose the SNMP version. Panopta supports SNMP v1, v2c, and v3.
The fields are described in the following table.
|Field||Description||Version 1 and 2c||Version 3|
|SNMP label||Enter a name for this SNMP credential.||✔||✔|
Select the SNMP version for this credential.
- SNMP version 1
- SNMP version 2c
- SNMP version 3
Enter the UDP port your SNMP server is listening to.
|SNMP community||Enter the SNMP community string for this SNMP credential.||✔|
Enter the associated SNMP user name.
|SNMPv3 Authentication Algorithm|
Select the authentication type to use for this SNMP credential.
|SNMPv3 Authentication Key|
Enter the key to be used for user authentication.
The key is the encrypted version of a cleartext password
|SNMPv3 Encryption Algorithm|
Select the encryption algorithm to use for this SNMP credential.
|SNMPv3 Encryption Key|
Enter the key associated with your selected encryption algorithm.
- Once the SNMP credential is set up, you have to import your network devices. There are two main ways to accomplish this; manually and with OnSight Discovery. If you want to use OnSight Discovery or the devices are already in Panopta, you can skip this section.
Add a network device manually
- Select + Add from the main navigation header then select Network Device.
- Add the IP address of the device, and select which group to put the device into. You also have the option to add tags or name the device.
The next screen will ask for the SNMP credential you set up in the last step.
- Choose a template. If you do not have any network device templates at this point, click Next.
- Select which OnSight you would like to monitor the device from (if you have more than one).
- Choose which timeline to use if any incidents occur.
- Select Add Device, the new device will populate under the group you selected.
Note: After adding the network device, the OnSight automatically detects its type and then provisions the standard metrics applicable to the device.
Add network devices with OnSight Discovery
To add network devices that your OnSight vCollector has discovered:
- Go to the OnSight page and select Discovered Instances. If you do not know how to set up discovery in your account, click here.
You will see the IP address or the instance name of the device that had been discovered and the services which were discovered on the device. The checkbox allows you to select multiple instances.
- Once instances are selected, choose the destination group and if required, apply a template.
||Note: After adding the network device, the OnSight automatically detects its type and then provisions the standard metrics applicable to the device.
You can also monitor SNMP with SNMP traps.
Configure the network device
To configure a network device, perform the following steps:
- Go to the Instance Details page of the network device that you want to configure.
- Select the name of the network device or the Edit icon.
The OnSight Configuration drawer will slide out.
- Edit the following settings as needed:
| Name||Change the name of the network device.|
| Server Key||The unique key used to reference this device.|
| Instance Group||Select an instance group for the network device.|
|Tags||Enter tags that can help define the network device. For example network, cisco. Press Enter after each tag. Known tags will be auto-suggested to you. Tags should not contain spaces.|
|Attributes||Add key-value pairs that can provide more structure to your instance metadata.|
|FQDNs and IPs || Add additional interface names. See Additional IP addresses or FQDNs.|
|Description||Enter a description for the template.|
|Parent Instance ||(Optional) The device upstream from this server that it depends on. If the parent device experiences an outage, this server's outage notifications will be suppressed.|
|Prometheus Endpoints||Add a Prometheus endpoint to the network device.|
Add an SNMP credential to the template.
|Select Credentials||The SNMP credential used for this device.|
|Recurring SNMP Discovery |
Enable this option if you want the OnSight to regularly scan the network device. Detected metrics will automatically be provisioned.
|SNMP Scan Frequency||This option only appears when the Recurring SNMP Discovery option is enabled. Specify how often (minutes) the network device is scanned for new metrics.|
|Port Metric Provisioning||Enable this option to auto-provision SNMP metrics.|
- Select Save Changes.
Monitor metric performance
In the Performance section of the network device's Instance Details page, each metric is presented differently. Device-level metrics use performance line charts along the top.
Port/interface-level metrics use a customized roll up display which shows interface stats in expandable rows.
Click on a specific row to expose all interface-specific performance and health metrics. The graphs will show both inbound/outbound stats stacked on the same graph with zooming ability. Click on the expand icon in the upper right-hand corner of a graph to see a fullscreen display.
