Monitoring vital signs

Management Station displays performance data on various aspects of the system every several seconds. These statistics, called vital signs, are displayed for the network, cluster, host, and service scopes. The vital sign statistics in this topic are specific to the Voice Platform services. For information on general vital sign statistics, see the Speech Suite documentation.

Note: By default, vital signs are stored only in memory. For information on collecting vital signs for generating system-performance reports, see the Speech Suite documentation.

To view the vital signs, follow these steps:

  1. Click the Monitoring & Control tab.
  2. Click System View.
  3. Select the scope from the network tree. Hosts and services must be online to display vital signs.
    1. Click Vital Signs on the toolbar. Depending on what you select, you can see:
    • Nuance Network: System CPU and memory-use statistics for all hosts in the network, and audio cache hits for the Nuance Speech Server.
    • Cluster: System CPU and memory-use statistics for all hosts in the cluster.

      Note: The vital signs displayed for the network and cluster scopes are the same. The values reflect the current scope. See Network and cluster vital signs.

    • Host: CPU and memory-use statistics for that host.
    • Service: CPU and memory-use statistics for that service. These vital signs are common to all services.

The Management Station charts the vital signs over a running 15 minute window and automatically refreshes the vital sign data every 30 seconds. For information on changing the refresh rate, see the Speech Suite documentation. For example:
