Version 1.2 of PowervRNI was just released and it contains 2 new cmdlets: 

  • Get-vRNIDataSourceSNMPConfig
  • Set-vRNIDataSourceSNMPConfig

You can use these cmdlets to see and update SNMP configuration on specific data sources. All Arista, Brocade, Cisco, Dell, and Juniper devices are data sources where SNMP can be enabled for richer data collection. This basically turns on interface counter collections, so you can have pretty graphs like this: 

Examples

To give you an idea of how to use these new cmdlets, check out the examples below. Of course, there is also documentation available in the module itself, viewable via the Get-Help cmdlet. 

Get-vRNIDataSourceSNMPConfig

It’s quite a mouthful, but the naming convention of PowerShell is clear: name it after what it does. 😉 So this cmdlet retrieves the SNMP configuration (if there’s any present) from a data source. It uses the values from Get-vRNIDataSource as input. Here’s an example that goes through all Cisco switch data sources:

As the result, you can see the SNMP configuration is disabled for this example. If it were enabled, you would see the details it’s using to poll the data source.

Set-vRNIDataSourceSNMPConfig

As the counterpart to Get-vRNIDataSourceSNMPConfig, the cmdlet Set-vRNIDataSourceSNMPConfig updates the SNMP configuration of a data source. It also takes the output of Get-vRNIDataSource as input, so you can use it in a piped manner. 

As a result, the data source with the nickname Core01 will get its SNMP configuration updated to use SNMP v2c and use the community snmpcommunity, and of course enable SNMP collection. 

Feedback

As interest in PowervRNI grows, I’m seeing a growing number of people using it to automate installation and operational tasks. Please continue to give me feedback on the module so we can continuously improve it!
