Version 105 of the Nutanix: Base Pack PowerPack contains new Dynamic Applications that support Nutanix Lifecycle Manager (LCM) and addresses an issue with a Dynamic Application.

  • Minimum Required SL1 Version: 10.2.0

  • Support Status: GA

Before You Install or Upgrade

Ensure that you are running version 10.2.0 or later of SL1 before installing "Nutanix: Base Pack" PowerPack version 105.

For details on upgrading SL1, see the relevant SL1 Platform Release Notes.

You can monitor Prism Elements or Prism Central. You must choose between monitoring Prism Elements or Prism Central as the root device, and then run discovery accordingly. It is recommended that you monitor Prism Central in all cases, unless you have only Prism Elements instances with no Prism Central instances.

Installing or Upgrading the PowerPack to Monitor Prism Element

By default, installing a new version of a PowerPack will overwrite all content in that PowerPack that has already been installed on the target system. You can use the Enable Selective PowerPack Field Protection setting in the Behavior Settings page (System > Settings > Behavior) to prevent the new version of the PowerPack from overwriting local changes for some commonly customized fields.

If you are currently using the Dynamic Applications in this PowerPack to monitor devices, collection errors might occur for one or two polling cycles during the installation of a new version. To prevent collection errors during an upgrade, you can optionally disable collection for monitored devices before performing the following steps and re-enable collection after the upgrade.

To install this PowerPack:

  1. Search for and download the PowerPack from the PowerPacks page (Product Downloads > PowerPacks & SyncPacks) at the ScienceLogic Support Site.
  2. In SL1, go to the PowerPacks page (System > Manage > PowerPacks).
  3. Click the Actions menu and choose Import PowerPack. The Import PowerPack modal appears.
  4. Click Browse and navigate to the PowerPack file from step 1.
  5. Select the PowerPack file and click Import. The PowerPack Installer modal displays a list of the PowerPack contents.
  6. Click Install. The PowerPack is added to the PowerPack Manager page.

For more information about using the PowerPack, see the Monitoring Windows Systems with PowerShell manual.

Installing or Upgrading the PowerPack to switch from Monitoring Prism Element to Monitoring Prism Central

If you monitor Prism Element and want to monitor Prism Central, upgrading to version 103 or greater of the PowerPack might require further steps, depending on if you need to keep historical data.

By default, installing a new version of a PowerPack will overwrite all content in that PowerPack that has already been installed on the target system. You can use the Enable Selective PowerPack Field Protection setting in the Behavior Settings page (System > Settings > Behavior) to prevent the new version of the PowerPack from overwriting local changes for some commonly customized fields.

If you need to preserve historical data, perform the following steps:

  1. See the Before You Install or Upgrade section. If you have not done so already, upgrade your system to the 10.2.0 or later release.
  2. Familiarize yourself with the Known Issues for this release.
  3. Download "Nutanix: Base Pack" version 105 from the Support Site to a local computer.
  4. Go to the PowerPack Manager page (System > Manage > PowerPacks). Click the Actions menu and choose Import PowerPack. Import "Nutanix: Base Pack" version 105. For details on importing PowerPacks, see the chapter on Installing a PowerPack in the PowerPacks manual.
  5. Click the Install button. For details on installing PowerPacks, see the chapter on Installing a PowerPack in the PowerPacks manual.
  6. Go to the Device Components page (Registry > Devices > Device Components). Find the Prism Element Component and select its checkbox.
  7. In the Select Action drop-down list, under Change Collection State, select Disabled (recursive).
  8. Discover your Prism Central device. After discovery, all Prism Element devices that are a part of Prism Central will appear as component devices under the root device.
  9. If you are discovering a Prism Central that contains Prism Element devices that have been previously discovered and user-disabled, the Prism Element devices will need to be re-enabled in order for normal Dynamic Application alignment and data collection to proceed. Go to the Device Components page (Registry > Devices > Device Components). Find the Prism Central device tree and select the checkboxes for the Prism Element devices that have been disabled in that tree. In the Select Action drop-down list, under Change Collection State, select Active(recursive).
  10. See the manual Monitoring Nutanix for instructions on using the PowerPack.

Known Issues

The following known issues affect version 105 of the Nutanix: Base Pack PowerPack:

  • When upgrading from version 102 or earlier of the PowerPack, the following stats—removed from version 103—will display as "No Data Found":
  • Nutanix: VM I/O Stats: CPU Usage
  • Nutanix: CVM I/O and Performance: CPU Utilization
  • When discovering a Prism Central that contains Prism Element devices that have been previously discovered and user-disabled, the Prism Element devices will need to be re-enabled after the Prism Element devices have been moved to the new Prism Central device tree so that normal Dynamic Application alignment and data collection can proceed.
  • Dynamic Application auto-alignment may take as long as 30 minutes to complete.
  • When discovering Prism Element and Prism Central devices, do not include both types of devices in the IP list for discovery, as the DCM tree will not fully build out and will be missing component devices. It is recommended that you either discover individual Prism Element clusters, or discover a Prism Central device with multiple Prism Element clusters.
  • When upgrading the PowerPack from a version earlier than version 101, duplicate virtual devices may be created in your Dynamic Component Map (DCM) when upgrading the PowerPack. This is due to the change to the unique ID and SL1 recognizing it as a new device.

To remove the old devices from the DCM, set the Component Vanish Timeout field (in either the Global Threshold Settings page [System > Settings > Thresholds> System], the Device Thresholds page for the component device [Registry > Devices > Device Manager > wrench icon > Thresholds], or the Device Thresholds page for a device higher in the component tree) on the DCM tree so that the old virtual devices get moved out of the DCM and only the newly discovered devices remain.

If you do not need to retain the old devices for historical data purposes, then the Component Purge Timeout field (in either the Global Threshold Settings page [System > Settings > Thresholds], the Device Thresholds page for the component device [Registry > Devices > Device Manager > wrench icon > Thresholds], or the Device Thresholds page for a device higher in the component tree) can be used to eventually remove those devices completely from the system.

  • Discovery and auto-alignment of Dynamic Applications can take up to about 30 minutes to complete.
  • If detailed discovery has completed and no Dynamic Applications are aligned, it may be due to a discovery Dynamic Application in the Microsoft HyperV v2.1 PowerPack. If you are monitoring Hyper-V, delete the Microsoft HyperV v2.1 PowerPack and install the updated Microsoft Hyper-V Server v100 PowerPack.
