Using the MOB to Explore the DiagnosticManager

The Managed Object Browser (MOB) is a graphical interface that allows you to navigate the objects on a server and to invoke methods. You can access the
DiagnosticManager
 using the MOB.
The following steps show how to explore
DiagnosticManager
.
  1. Start the mob by typing the MOB URL (
    https://hostname.yourcompany.com/mob
    ) into a Web browser.
  2. In the
    ServiceContent
     data object, click the link (
    ha-diagnosticmanager
     or
    DiagMgr
    ) in the
    Value
     column for the
    diagnosticManager
     property, to navigate to the
    DiagnosticManager
     for the system.
    • For ESXi,
      ha-diagnosticsmanager
       is the managed object ID.
    • For vCenter Server,
      DiagMgr
       is typically the managed object ID.
  3. Click the link to the reference to display the managed object reference to the
    DiagnosticManager
     in the MOB.
    DiagnosticManager
     provides three operations that allow you to obtain information about the descriptions currently available in the log file and log file content.
    Because
    DiagnosticManager
     can track multiple ESXi systems, you can use the
    QueryDescriptions
     operation to return the names of keys used for all hosts. From this array, select the key for the host from which you want to obtain the log file.
  4. On
    QueryDescriptions
    , click the
    Invoke Method
     link.
    The vCenter Server system returns the contents of the log file for the selected host as a string array for the
    lineText
     property of
    DiagnosticManagerLogHeader
    .
The string array returned through the MOB in this way is the content of the log file. The content contained in the log file is the same content that is available through the following other mechanisms:
  • Displayed in the vSphere Client
  • Included in a diagnostic bundle created through the
    DiagnosticManager.GenerateLogBundles_Task
     method.
  • Available in the
    hostd.log
     file
  • Returned to a client application that you write
