The Stat Server Cluster

You configure a Stat Server cluster as Solution object within Configuration Server of type Multimedia. This solution defines the connectivity parameters to all Stat Server instances, or nodes, within the cluster. Other applications can belong to the cluster as well (including other Stat Server applications that do not service the cluster); however, this chapter focuses on setup of Stat Server nodes for a Stat Server cluster only. The Stat Server Solution object also defines and stores all of the statistical parameters that service the cluster.

Each Stat Server instance within the cluster might connect to:

  • The T-Controller interface of one or more SIP Server instances within a SIP Cluster and/or
  • One or more Interaction Proxy interfaces of one or more SIP Server instances within a SIP Cluster

However, in order to monitor the entire SIP cluster, a Stat Server solution must connect to:

  • All T-Controller interfaces of the SIP cluster—you can configure all such connections within as few as one Stat Server instance—and
  • Every Interaction Proxy interface—using as many Stat Server instances that are required to handle call volume.

The figure in the Configuring the Components of a Stat Server Solution topic illustrates one possible Stat Server solution configuration.

Any statistic for any object could be requested from any of the Stat Server instances within the cluster; therefore, each Stat Server instance shares a connection to all other Stat Server instances to proxy statistical requests and events between a particular aggregation instance and client.

You configure each Stat Server instance as an Application object of Stat Server type following the instructions and precautions described in Configuring a Stat Server Application.

Upon startup, each Stat Server instance retrieves the name of its solution from the value specified with the -cluster command-line parameter (see also Mandatory Options). Using this information, each Stat Server instance then reads the configuration specified within the Stat Server Solution object, and establishes connections with all other Stat Server instances configured within the solution.
