3.7 Ganglia Configuration and Monitoring

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

3.7.1 Configure Ganglia

Use the Ganglia Configuration tool to configure monitoring for the appliance. The Ganglia gmond daemon uses UDP port 8649 for communications. The gmetad daemon uses TCP port 8649 for metrics data. You can also enable or disable non-secure HTTP viewing of the metrics on port 9080.

  1. Log in to the Appliance Management Console as the vaadmin user.

  2. Click Ganglia Configuration .

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

      • If you already have a monitoring system that you plan to use for the appliance.

      • If you plan to configure a dedicated appliance for viewing monitoring information.
