Prerequisites for Monitoring VMware vCenter Servers

Before performing the steps for configuring a vCenter server, you must:

  • Have access to a VMware vCenter server that monitors your ESXi and ESX servers.
  • Have access to the vCenter server using the vSphere web client.

If the Windows Server that hosts the vCenter server is SNMP-enabled, you must also configure your ESXi or ESX servers for communication using SNMP. To do so, you must: 

Creating a Read-Only User Account for Monitoring

Administrative users are the only default user type that have the level of access SL1 requires to collect data from the VMware vCenter web service. If you do not want to use the username and password of an administrative user in the SOAP/XML credential, you can set up a custom user role with the specific read-only access SL1 requires to the VMware vCenter web service.

To create a custom user role that grants the read-only access SL1 requires, perform the following steps:

  1. Open your vCenter client at https://<vcenterservername>/ui

  1. Select Menu > Administration from the drop-down.
  2. In the menu at the left of the page, click Access Control > Roles. The Roles page appears:

  1. Click the plus sign () to add a new Role. The New Role page appears:

  1. In the pane on the left, select Storage views and select the View checkbox. Click Next.

  1. In the next screen, enter a name for the role in the Role name field. Optionally, you can enter a description in the Description field.

  1. Click the Finish button.

To assign the custom role to a user account, perform the following steps:

  1. In the vCenter client, select your vCenter server containing the hosts and clusters you are monitoring and click the Permissions tab.

  1. Click the plus sign () to add permissions.

  1. Enter values in the following fields:
  • User. Select your domain and add the user in the field below.
  • Role. Select the role that you just created.
  • Propagate to children. Select this checkbox.

  1. Click the OK button.

Configuring a SOAP/XML Credential

To use the Dynamic Applications in the VMware: vSphere Base Pack PowerPack, you must configure a SOAP/XML credential for the VMware web service.

SL1 includes a VMware credential type that you can use to connect with the VMware web service during guided discovery. This credential type uses field names and terminology that are specific to VMware vSphere.

Alternatively, you could monitor VMware using a generic SOAP/XML credential that does not include VMware-specific fields. For more information, see the section on Configuring a SOAP/XML Credential for VMware.

To define a VMware-specific credential:

  1. Go to the Credentials page (Manage > Credentials).

  2. Click the Create New button and then select Create VMware Credential. The Create Credential modal page appears:

    An image of the VMware Create Credential page.

  1. Supply values in the following fields:

  • Name. Name of the credential. Can be any combination of alphanumeric characters, up to 64 characters. This field is required.

  • All Organizations. Toggle on (blue) to align the credential to all organizations, or toggle off (gray) and then select one or more specific organizations from the What organization manages this service? drop-down field to align the credential with those specific organizations. This field is required.

To learn more about aligning credentials and organizations, see Aligning Organizations With a Credential.

  • Timeout (ms). Time, in milliseconds, after which SL1 will stop trying to communicate with the device from which you want to retrieve data.
  • VMware web service username. The VMware username for the VMware web service account. This field is required.
  • VMware web service password. The VMware password for the VMware web service account. This field is required.
  • URL. The URL of the VMware web service that you want to monitor. This field is required.
  • You can include the variable %D in this field. SL1 will replace the variable with the IP address of the device that is currently using the credential. For component devices, SL1 will replace %D with the IP address of the root device.
  • You can include the variable %N in this field. SL1 will replace the variable with the hostname of the device that is currently using the credential. If SL1 cannot determine the hostname, SL1 will replace the variable with the primary management IP address for the current device.

Click the URL field for a set of options for formatting the URL: http(s)://Host:Port/Path | %D = Aligned Device IP | %N = Aligned Device Name. For example: https://%D:433/<sample path>.

  1. Click Save & Close.

If you would like to test your credential using the Credential Tester panel, click Save & Test. For detailed instructions on using the Credential Tester panel, see the Using the Credential Tester Panel section.

To modify either of the VMware credential templates in the SL1 classic user interface, perform the following steps:

  1. Go to the Credential Management page (System > Manage > Credentials).

  1. Click the wrench icon () for the "VMware Server Example" credential. The Credential Editor modal page appears:

  1. Supply values in the following fields:
  • Profile Name. Enter a new name for the credential.
  • URL. In most cases, you can use the default setting.

  • Embed Value [%1]. Enter the username SL1 will use to connect to the VMware web service in the format <domain>/<username>. For example, silo_domain\john_user
  • Embedded Password [%P]. Enter the password SL1 will use to connect to the VMware web service.
  1. Click the Save As button to save your changes as a new credential.

Do not click the Save button, as it will save over the example credential, which you may need for future use.

Testing the VMware Credential

SL1 includes a Credential Test for VMware. Credential Tests define a series of steps that SL1 can execute on demand to validate whether a credential works as expected. For more information about creating and managing credential tests, section on Managing Credential Tests.

The VMware Credential Test can be used to test a SOAP/XML credential for monitoring VMware using the Dynamic Applications in the VMware: vSphere Base Pack PowerPack. The VMware Credential Test performs the following steps:

  • Test Reachability. Attempts to reach the vCenter server using ICMP.
  • Attempt VMware Connection. Attempts to connect to the VMware service using the account specified in the credential.

To test the VMware using the Credential Tester panel:

  1. Go to the Credentials page (Manage > Credentials).
  2. Locate the VMware credential that you created, click the Actions button (), and then select Test.
  1. The Credential Test Form modal page appears. Fill out the following fields on this page:
  • Select Credential Test. Select the "VMware Credential Test".
  • Collector. Select the All-In-One Appliance or Data Collector that will run the test.
  • IP or Hostname to Test. Type the IP address of the vCenter server.

The credential tester could fail if used on an ipv6 address. ScienceLogic recommends inserting square brackets ( [ ] ) around the address ([<ipv6-address>]) in the test to resolve the issue.

  1. Click Run Test button to run the credential test. The Testing Credential window appears.

    The Testing Credential window displays a log entry for each step in the credential test. The steps performed are different for each credential test. The log entry for each step includes the following information:

    • Step. The name of the step.
    • Description. A description of the action performed during the step.
    • Log Message. The result of the step for this execution of the credential test.
    • Status. Whether the result of this step indicates the credential and/or the network environment is configured correctly (Passed) or incorrectly (Failed).
    • Step Tip. Mouse over the question mark icon () to display the tip text. The tip text recommends what to do to change the credential and/or the network environment if the step has a status of "Failed".

Managing Site Recovery Manager Placeholder Virtual Machines

As of version 307 of the VMware: vSphere Base Pack, SRM (Site Recovery Manager) placeholder virtual machines will not be discovered or modeled on a new discovery. In order to model them, you need to adjust the "Hide PlaceHolder VMs" threshold in the following Dynamic Applications:

  • VMware: ClusterComputeResource VM Discovery

  • VMware: HostSystem VM Discovery

  • VMware: ResourcePool VM Discovery

To configure the "Hide Placeholder VMs" threshold:

  1. Navigate to the Dynamic Applications Manager page and search for the appropriate Dynamic Application.
  2. Click the wrench icon () to edit the Dynamic Application properties.
  3. Click on the Thresholds tab.
  4. Click the wrench icon () next to "Hide PlaceHolder VMs".

  5. The Threshold Value field is set to 1 ("true") by default. This means that on a new discovery, SRM (Site Recovery Manager) placeholder virtual machines will not be discovered or modeled. To model them, change the value to 0 ("false").

  6. Click Save.

  7. Repeat this process with the other Dynamic Applications listed above if needed.

Image of adjusting the Threshold Value for Hide PlaceHolder VMs on the Thresholds tab of a Dynamic Application.

This will not affect existing placeholder virtual machines that have already been modeled. If you are updating from an earlier version and wish to hide the placeholders, any that already exist should be deleted after upgrading.

 

After a failover, any new placeholder virtual machines will remain modeled, and must be either manually deleted or allowed to vanish.

Any future updates to the VMware: vSphere Base Pack PowerPack will reset the "Hide PlaceHolder VMs" threshold to the default value. You will need to configure the threshold again after upgrading.

Configuring the Hide Placeholder VMs Threshold for a Parent Device

After an SRM placeholder parent device has been discovered, you can configure the threshold for the parent device to affect any virtual machines under that device. For example, if you want to view placeholders for a specific host, but not others, you can configure the threshold to show or hide them.

  1. Navigate to the Device Manager page (Devices>Device Manager) and search for the SRM (Site Recovery Manager) parent device you want to configure.

  2. Click the wrench icon () to edit the device properties.

  3. Click on the Thresholds tab.

  4. Search for the appropriate Dynamic Application that discovered the parent device. It will be one of the options listed below, depending on the device:

    • VMware: ClusterComputeResource VM Discovery

    • VMware: HostSystem VM Discovery

    • VMware: ResourcePool VM Discovery

  5. The Hide Placeholder VMs threshold is set to 1 ("true") by default. This means that on a new discovery, SRM (Site Recovery Manager) placeholder virtual machines will not be discovered or modeled. To model them, change the value to 0 ("false").

  6. Click Save.
