7.5 Ganglia Configuration

Ganglia is a scalable, distributed monitoring system that allows you to gather important information about your iPrint Appliance system. The default metrics that you can monitor are CPU, disk, load, memory, network, and process.

  1. On a Web browser, use either the DNS name or the IP address to access the Management Console. For example, https://10.0.0.1:9443 or https://iprint.example.com:9443.

  2. Click the Appliance System Configuration icon.

  3. Click Ganglia Configuration.

  4. As necessary, change the following Ganglia configuration options:

    Enable Full Monitoring Services: Select this option to receive and store metrics from other appliances, and to allow the Ganglia Web Interface to run on the same machine as the iPrint appliance.

    You might want to disable Ganglia monitoring by deselecting this option if:

    • You already have a monitoring system that you plan to use for iPrint.

    • You plan to configure a dedicated appliance for viewing monitoring information. (You do this by selecting Unicast below, then specifying the DNS name or IP address of the appliance where monitoring information will be collected.)

    Enable monitoring on this appliance: Select this option to enable Ganglia monitoring on this appliance.

    • Multicast: Select this option to send monitoring information to other appliances on the network.

    • Unicast: (Recommended) Select this option to send monitoring information to a single destination.

      Unicast mode is recommended for improving performance of the iPrint system.

      Publish to: Specify the URL where Ganglia sends monitoring information when it is running in Unicast mode.

  5. (Optional) Click Reset Database to remove all existing Ganglia metrics from this appliance.

    This option is not related to the iPrint database.

  6. Click OK.
