Customize the Default Machine Agent Metric Collection

  1. Locate the task-template.xml file. This file is located in the <machine_agent_home>/monitors/JavaHardwareMonitor/ directory when the Machine Agent starts the first time.
  2. Edit the task-template.xml file:
    • To enable aggregation operation for localhost (lo) network metrics, change the value of the aggregate attribute (for the network element "lo") to "true".
    • To enable monitoring for a virtual disk, set the value of the enabled attribute to "true" for that disk.
    <config>
<disk aggregate="false" enabled="false">sunrpc</disk>
<disk aggregate="true" enabled="true">/dev/sdb1</disk>
<disk aggregate="false" enabled="false">proc</disk>
<disk aggregate="false" enabled="false">none</disk>
<disk aggregate="false" enabled="false">devpts</disk>
<disk aggregate="true" enabled="true">/dev/sda1</disk>
<disk aggregate="false" enabled="false">nfsd</disk>
<disk aggregate="true" enabled="true">/dev/mapper/saas4-binlog</disk>
<disk aggregate="false" enabled="false">sysfs</disk>
<disk aggregate="false" enabled="false">tmpfs</disk>
<network aggregate="true" enabled="true">lo</network>
<network aggregate="true" enabled="false">sit0</network>
<network aggregate="true" enabled="true">eth0:1</network>
<network aggregate="true" enabled="true">eth0</network>
<network aggregate="true" enabled="false">eth1</network>
</config>
  3. To prevent the Machine Agent from overwriting the file, rename the task-template.xml file to task.xml .
  4. To monitor a special device that is not enabled, add a file named task.xml in the <machine_agent_home>/monitors/JavaHardwareMonitor/ directory.The format of the task.xml file must be exactly the same format as the task-template.xml file. Not all disks and networks must be included in the task.xml file. If the Machine Agent finds a disk or a network that is not in the task.xml file, then it applies the default properties.
  5. Restart the Machine Agent.
