Adding a Performance-Based Load Balancing with Load Feedback (targets computed from configured weights) Property to a Domain
This property type is similar to Performance-Based Load Balancing with Load Feedback, except that you can give each traffic target a weight that is taken into account when GTM distributes traffic.
Before you begin
To create load feedback and performance-based property types you first need to create a new domain and enable Load Feedback. You cannot go back into a domain and change the Load Feedback setting to use these properties. To create a new domain, see Create a new domain.
- On the Traffic Management Domains page, select the domain for which you want to add a property and click Add New Property.
- Enter a name in the Property Name field. This is required.
Performance-Based Load Balancing with Load Feedback (targets
computed from configured weights) from the Property Type list
and enter the following information or accept the defaults:
- Minimum Live Percentage (optional)
- Comments (optional)
- DNS TTL
- IP Type
- Click Add To Change & Next. The Traffic Targets page appears.
Enter server names or Handout
CNAMEs for each target.
If a handout CNAME is given, traffic distributed to a traffic target will be sent to where the CNAME points. If servers are also given liveness tests from these servers will be used to determine if the traffic target is available. If no server is given, this traffic target is always considered available.
- Click Balance All Targets Evenly to split the load among the targets. In this example the split is 25 and 75 percent between the two targets. You can manually enter a load value using the Data Center Weight field.
To add a new target at this stage, click Add New Target.
If you do not have an available data center, a clone for an existing one is
To enable or disable a target, use the slider. To remove a target, click X.
- Click Add To Change List & Next. The Liveness Test page appears.
Enter the following information
for at least one test, or click Skip to proceed
to the Review page. You can create a test later. This example uses the HTTP
protocol. Other protocols will have different or fewer fields to fill out. See
Liveness Test for more information on these fields.
- Test Name (required)
- Test Interval
- Test Timeout
- Port: specify the port number for requesting the test object
- Protocol: select a type from the menu (for example, HTTP, FTP, TCP)
- Test Object Path (optional): only enter the local part of the URL for the test object (for example, /data/results/test.html)
- Host Header (optional)
- HTTP/FTP errors: Select the responses you want to consider for server failures.
- Authentication: If you are using password authentication, provide a username and password.
Click Add To Change List &
Next. The Review page appears.
On the Review page you can view the basic property settings, traffic targets, and liveness
tests and edit the settings if you want to make revisions.Note: Akamai will use the servers specified in the data center to determine if the traffic target is available. If the liveness test fails on all the servers in a data center, Akamai will stop sending traffic. Also, if a handout CNAME is given, traffic distributed to a traffic target will be sent to where the CNAME points. If servers are also given liveness tests from these servers will be used to determine if the traffic target is available. If no server is given, this traffic target is always considered available.
