All VirtualMetric components use VirtualMetric API to communicate with VirtualMetric DB. You can easily install two or more VirtualMetric API roles to form a high availability VirtualMetric API.

Load balancing is a way to distribute workload across multiple web servers. The purpose is to attain optimal resource utilization, maximize request throughput, minimize response time, and avoid server overload.

Load balancers use various algorithms to accomplish this task. One of the simplest algorithms is round robin, which sends each new request to a different web server in an attempt to load all servers equally. Other algorithms send specific types of requests to specific servers in an attempt to reduce response time.

Create an entry for your VirtualMetric API roles on the load balancer. After that you can reach to load balancer entry instead of VirtualMetric API roles IP addresses.

Information

For information about setting up an entry on Load Balancer, please contact your Load Balancer support.

Installing VirtualMetric API is easy and works like other Windows-based applications. To install VirtualMetric API, run the installation setup program that you have downloaded.

Confirm the question of the Windows User Account Control with Yes to allow the program to install. The VirtualMetric API installation dialog will guide you through the installation process.

You will see Welcome Screen. Please click Next to continue.

Accept the license agreement and click Next.

In this step, you will configure VirtualMetric API settings.

• You can use either IP address or FQDN for VirtualMetric API connectivity. All servers will use this address for inventory and performance stats collection. So if you use FQDN, FQDN address should be resolved by all servers.
• By default, VirtualMetric API listens TCP 8080. You can change following port configuration on this step to use a different port. After you specify port address, VirtualMetric will setup its REST API with this port configuration.
• Setup will add firewall rule into Windows Firewall as part of the installation.

Please click Nextto continue.

Attention Required

VirtualMetric API address should be reachable by all servers. Please visit Firewall Configuration section to make sure.

Security Information

If you want to secure VirtualMetric API connections with an SSL certificate, please visit the Setup SSL Certificate section.

In this step, you will configure VirtualMetric Database settings.

• You should enter your Microsoft SQL Server Instance information and User information in this step.
• Our setup supports Windows and SQL Authentication methods.

Please click Next to continue.

Review the setup location and click Next.
