## Managed Object Description

Provides an interface for obtaining diagnostic information on a host (e.g. generating and retrieving support logs on the host, reading audit records). For VirtualCenter, this includes the log files for the server daemon. For an ESX Server host, this includes detailed log files for the VMkernel.

Methods

Methods defined in this Managed Object

# BrowseDiagnosticLog(browse)

Returns part of a log file. Log entries are always returned chronologically, typically with the newest event last.

Required Privileges
  Global.Diagnostics

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the DiagnosticManager used to make the method call.
host* P | ManagedObjectReference to a HostSystem | Specifies the host. If not specified, then it defaults to the default server. For example, if called on VirtualCenter, then the value defaults to VirtualCenter logs. Since 2.0
key P | xsd:string | A string key specifying the key for the log file to browse. Keys can be obtained using the queryDescriptions method. Since 2.0
start* P | xsd:int | The line number for the first entry to be returned. If the parameter is not specified, then the operation returns with lines starting from the top of the log. Since 2.0
lines* P | xsd:int | The number of lines to return. If not specified, then all lines are returned from the start value to the end of the file. Since 2.0

*Need not be set P Required privilege - see tooltip for details

Return Value

Type | Description
--- | ---
DiagnosticManagerLogHeader | A LogHeader that includes the log lines. Sometimes fewer log lines are returned than were requested. For example, fewer lines are returned than expected if the client requests lines that do not exist or if the server limits the number of lines that it returns. If zero lines are returned, then the end of the log file may have been reached.

Faults

Type | Description
--- | ---
CannotAccessFile | Thrown if the key refers to a file that cannot be accessed at the present time.
RuntimeFault | Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.

# EmitSyslogMark

Issue a "mark" to syslog and the audit trail. The specified message string will be written to syslog and the audit trail. The "mark" audit record will contain the message string in its comment parameter.

# FetchAuditRecords

Retrieve audit records from their storage on the specified host. Audit records are stored on the host in a (large) FIFO. The FIFO is continuously being written to due to system activities. It is the responsibility of the caller to issue reads fast enough to keep ahead of the write traffic.

Required Privileges
  Global.Diagnostics
Since
  vSphere API 7.0.3.0

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the DiagnosticManager used to make the method call.
token* P | xsd:string | The token to be used for the operation. The first call must be made without a token. All subsequent calls use the token returned in AuditRecordStatus. Since vSphere API 7.0.3.0

*Need not be set P Required privilege: token

Return Value

Type | Description
--- | ---
DiagnosticManagerAuditRecordResult |

Faults

Type | Description
--- | ---
InvalidState | The reader has failed to keep up with the write data rate. Data has been lost. It is up to the caller to decide how to react to this. One possibility is to "start again from the beginning" with a call with no token.
RuntimeFault | Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.
SystemError | One more more errors (on the host) have occurred. One or more error strings are available to detail the issues.

# GenerateLogBundles_Task(generateLogBundles)

Deprecated. - since version 5.0 M/N it is recommended to use the CGI interface for the host bundles, use the address instead: https:<>/cgi-bin/vm-support.cgi for the VC bundles, use https:<>/appliance/support-bundle

The caller can download the bundles using an HTTP GET operation for each returned URL. Bundles are usually available for at least 24 hours, but the caller should not assume that the returned URLs are valid indefinitely. Servers often automatically delete generated diagnostic bundles after some given period of time.

Instructs the server to generate diagnostic bundles. A diagnostic bundle includes log files and other configuration information that can be used to investigate potential server issues. Virtual machine and guest operation system state is excluded from diagnostic bundles.

Required Privileges
  Global.Diagnostics

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the DiagnosticManager used to make the method call.
includeDefault P | xsd:boolean | Specifies if the bundle should include the default server. If called on a VirtualCenter server, then this means the VirtualCenter diagnostic files. If called directly on a host, then includeDefault must be set to true. Since 2.0
host* P | ManagedObjectReference[] to a HostSystem[] | Lists hosts that are included. This is only used when called on VirtualCenter. If called directly on a host, then this parameter must be empty. Since 2.0

*Need not be set P Required privilege - see tooltip for details

Return Value

Type | Description
--- | ---
ManagedObjectReference to a SmsTask | This method returns a Task object with which to monitor the operation. Upon success, the result property in the Task contains a list of DiagnosticManagerBundleInfo objects for each diagnostic bundle that has been generated.

Faults

Type | Description
--- | ---
LogBundlingFailed | Thrown if generation of support bundle failed.
RuntimeFault | Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.
TaskInProgress | Thrown if there is a pending request to generate a support bundle.

Events

Type
None

# QueryDescriptions(queryDescriptions)

Returns a list of diagnostic files for a given system.

Required Privileges
  Global.Diagnostics

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the DiagnosticManager used to make the method call.
host* P | ManagedObjectReference to a HostSystem | Specifies the host. If not specified, then it defaults to the server itself. For example, if called on VirtualCenter, then the value defaults to VirtualCenter logs. When called on an ESX server host, the host should not be specified. Since 2.0

*Need not be set P Required privilege: host

Return Value

Type | Description
--- | ---
DiagnosticManagerLogDescriptor[] |
