Service Impact and Root Cause Analysis

When combined with the Zenoss Service Dynamics product, this ZenPack adds built-in service impact and root cause analysis capabilities for services running on IBM Power. The service impact relationships shown in the diagram and described below are automatically added. These will be included in any services that contain one or more of the explicitly mentioned components.

IBM and Power Server Impact Relationship Diagram

Internal Impact Relationships

  • Managed Systems, Logical Partitions, HMC Service Processor and Processor Pools impacts the related HMC Server.
  • HEAs, HEA Ports, Logical HEAs, Logical HEA Ports, I/O Devices, I/O Pools, Port Groups, Processor Pools, Logical Partitions, Virtual Ethernet Adapters, Virtual SCSI Adapters failures impact the related Managed Systems which impacts the HMC Server.
  • Logical Partitions failures impact the related Logical HEAs, Logical HEA Ports, I/O Devices, I/O Pools, Processor Pools, Virtual Ethernet Adapters, Virtual SCSI Adapters.
  • Managed Systems failures impact the related Logical Partitions.
  • Port Groups failures impact HEA Port.
  • Logical HEA Ports failures impact Port Groups, HEAs.
  • I/O Pools failures impact I/O Devices which impacts the Logical Partitions.

Most of the impacts described above follow the default policy of a node being in the worst state of the nodes that impact it. For example, an HMC Server failure will imply that all related hosts are also failed.

Zenoss Analytics

The following steps are applicable only for Zenoss Analytics 5.x.x. In Analytics 6.0.0, any third-party reporting tool can be used to generate reports.

This ZenPack provides additional support for Zenoss Analytics. Perform the following steps to install extra reporting resources into Zenoss Analytics after installing the ZenPack.

  1. Copy from $ZENHOME/ZenPacks/ZenPacks.zenoss.IBM.Power/analytics/ on your Zenoss server.
  2. Navigate to Zenoss Analytics in your browser.
  3. Login as superuser.
  4. Remove any existing IBM Power ZenPack folder.
    1. Choose Repository from the View menu at the top of the page.
    2. Expand Public in the list of folders.
    3. Right-click on IBM Power ZenPack folder and choose Delete.
    4. Confirm deletion by clicking OK.
  5. Add the new IBM Power ZenPack folder.
    1. Choose Server Settings from the Manage' menu at the top of the page.
    2. Choose Import in the left page.
    3. Remove checks from all check boxes.
    4. Click Choose File to import a data file.
    5. Choose the file copied from your Zenoss server.
    6. Click Import.You can now navigate back to the IBM Power ZenPack folder in the repository to see the following resources added by the bundle.


Adding HMC Server

Use the following steps to start monitoring HMC Server using the Zenoss web interface.

  1. Navigate to the Infrastructure page.

    Add Device

  2. Navigate to organizer Devices/Server/IBM/Power/HMC.

  3. Choose Add a Single Device from the add button.
  4. Fill out the form.

    Add Dialog

    • Name can be anything you want.
    • Hostname or IP must be resolvable and accessible from the collector server chosen in the Collector field.
    • Click ADD.
    • IBM HMC Server will be added in the /Devices/Server/IBM/Power/HMC device class.

Use the following steps for successful modeling.

  1. Select the device added.
  2. Navigate to Configuration Properties.

    Model device

  3. Provide the values for zCommandUsername and zCommandPassword.

  4. Model the device.

    Use zIBMLPARsDisableModeling property to disable modeling of LPARs and zIBMLPARProfilesDisableModeling property to disable modeling of LPAR Profiles. By default both properties are set to False, so LPARs and LPAR Profiles will be modeled. If you want to disable the modeling of LPARs, LPAR Profiles or both, set the value of these properties to True.


  • Alternatively you can use zenbatchload to add devices from the command line.
  • To do this, you must create a file with contents similar to the following.
  • Replace all values in angle brackets with your values minus the brackets.
  • Multiple devices can be added under the same sections.

    '/Devices/Server/IBM/Power/HMC' <device name>  setManageIp="<IP Address>", zCommandUsername='<username>', zCommandPassword='<password>'


    /Devices/Server/IBM/Power/HMC HMC_1 setManageIp='', zCommandUsername='hcladmin', zCommandPassword='root123'
  • You can then load the Devices using zenbatchload with the following command.

    zenbatchload <filename>
