I just started to use Private Last Mile and have PLM peers installed. When I created a Private Last Mile test, on the test configuration page, I saw no peers listed there to select.

Anything else needs to be done?


Dynatrace Synthetic Classic: Private Last Mile (PLM)


One thing to clarify is that PLM tests are not directly scheduled to run from the PLM peers you have installed. PLM tests are scheduled onto the PLM Peer Populations. Then use the criteria defined in the Peer Population to look for peers. After that the tests are assigned to those peers that are found with the same criteria.

In other words, Peer Population is a group of peers. That you define criteria to search for peers. So that you can easily group multiple peers together when you need it. (See here for details about how does PLM tests scheduling work.)

Thus under the test configuration page, what listed there is the list of the peer populations you have created but not the peers installed.

PLM Peer Population is created on the Adding peer population page. Click here to go to the related doc page for details. There can be just one peer or multiple peers under one peer population. 

To summarize, please set up peer populations before you set up PLM tests, 

Best Practices:

On the Configure New Private Peer Population page, there are 11 fields/criteria can be configured:

How to set the 2 fixed fields:

--Name it with something that makes sense to you and your team. With which you can easily recognize what peers are included under the Peer Population.

Not recommended to name it with the same name as your Private Last Mile Network. Two different things with the same name will be confusing.

It is commonly used to include the Region/Country where the peers are located and/or your team or project name in the name of a Peer Population Name.

For example: SyntheticUKPLMPeers or DynatraceUSPLMPeers

--It is the name of your Private Last Mile Network. Which was provided to you when Private Last Mile was enabled for your account, either by your Account Manager, or directly sent by the Licensing team.

When you configure your PLM peers, on the Preferences page, the "Account Name" there is actually  "(Network) Account Name" which means the same thing here: name of your Private Last Mile Network.

How to set the custom fields:

If you want to create a peer population which includes all your peers, setting up the two fixed fields is enough. No need to select custom fields. Since all your peers are linked with a PLM Network, with PLM Network(s) selected, that is enough criteria for our system to find all your peers.

To create a PLM peer population which includes some of your peers, select either one of the custom fields below is enough.
