Peer Populations

Use Peer Populations to group together selected machines by geographic configuration, ISP, bandwidth, or any other criterion that may affect performance.

Peer Population types

Two types of Peer Populations are available for tests:

  • Global Peer Populations
  • Account-specific Peer Populations

Global Peer Populations

Global Peer Populations are created by Dynatrace. These "out of the box" Peer Populations enable you to quickly select a Peer Population when configuring tests.

You cannot edit or delete these Peer Populations from your account. However, you can copy and modify them to create account-specific Peer Populations.

Global Peer Populations are available for Last Mile tests only. All Private Last Mile Peer Populations are specific to the account.

Account-specific Peer Populations

Account-specific Peer Populations are created by your account administrator.

Create account-specific Peer Populations to group specific criteria to meet your requirements. For example, an account-specific Peer Population may be created to monitor from California and Arizona using only Low Broadband peers.

Account-specific Peer Populations can be edited, copied, or deleted from your account. These populations are availablae for Last Mile and Private Last Mile tests.

Viewing Peer Populations

To see the Peer Populations that are available to your account:

  1. Click > Measurement locations.

  2. Select the tab:

    • Last Mile tab to view the public Peer Populations.
    • Private Last Mile tab to view the private Peer Populations.

In either the Last Mile or Private Last Mile tab:

Peer Populations table

The Last Mile tab and the Private Last Mile tab provide the same information about their respective Peer Populations:

  • Name – The name of the Peer Population. An icon to the left of the name indicates a default Peer Population.
    The Peer Populations are listed by default in the Peer Population and IP Preference section of the test settings.
  • Created By – The name of the person who created or modified this Peer Population. The text [global] identifies Global Peer Populations for Last Mile.
  • Create Date:
    • For account-specific Peer Populations, the date is when this population was either created or last modified.
    • For Global Peer Populations, the date is the day and time this population was last modified.

By default, the table is sorted by the creation date, with the most recently created Peer Population at the top. Select any column heading to sort by that column.

Peer Population information

Information on the selected Peer Population appears to the right of the table.

By default, the first row in the table is selected and the information for that population appears on the page. Select a row to view information for a Peer Population.

For each Peer Population, the following information appears:

  • Fill Rate Probability. An icon indicates the fill rate probability for this Peer Population. For more information, see below.
  • Peer Population name, creator, and day and time this population was created or last modified.
  • Included and excluded criteria: countries, states/provinces, ISPs, available bandwidth, and connection type.

Depending on the Peer Population selected, use the Action menu to edit, copy, or delete this Peer Population.

Fill Rate Probability

The Fill Rate Probability indicates the likelihood that the number of measurements selected can be achieved by the selected Peer Population:

  • Excellent – The remaining capacity of the selected Peer Population is greater than needed to fulfill the requested measurements.
  •  Good – The remaining capacity of the selected Peer Population is estimated to be enough to fulfill the requested measurements.
  •  Poor – The remaining capacity of the selected Peer Population is estimated to be insufficient to fulfill the requested measurements.
  •  Not Available – The fill rate probability is not available for this Peer Population.
