Operating System Information

The Performance Monitor Agent provides statistics and allows thresholds to be set for various system performance parameters. Information is available for the following subsystems: System, Server, Processor, Memory, Paging File, Cache, Physical Disk, Logical Disk, Network, TCP and Processes.

The Performance Monitor Agent is a sub agent of the Foundation Agent. This agent replaces the previous OS Management Agent (Patrol for Compaq) and the previous threshold settings are not maintained. The agent obtains  performance data from the Microsoft OS-supported Windows Management Information (WMI). WMI is installed as part of the OS on Microsoft Server 2003 and Windows 2000.  For Microsoft Windows NT4, WMI must be installed by the user.

NOTE:  If the system does not have WMI installed, download and install it from the Microsoft website at:www.microsoft.com/downloads/release.asp?ReleaseID=18491

The install status of the Performance Monitor Agent is verified from Start -->Settings  -->Control Panel under the services section of the HP Management Agents Control Panel applet. If needed, to activate the Performance Monitor feature, select Performance Monitor from the Inactive Agents section and click the Add button. The Performance Monitor  information then is displayed under Active Agents section.

Disk Monitoring Top

To enable physical and logical disk monitoring on Windows NT and Windows 2000 systems the command must be run:

 DISKPERF [-Y[D|V] | -N[D|V]] [\\computername]

For Windows 2000, Disk Performance Monitoring can be turned on/off as needed by using this command.

For Windows NT4, Disk Performance Monitoring cannot be turned off once it is turned on.

For Windows Server 2003, Disk Performance Monitoring is on by default and cannot be turned off.

Threshold Alarms Top

Warning and critical threshold limits can be set for the properties where indicated in the list below.  Alarms are sent when the performance property value meets the threshold conditions and stays for 15 data collection intervals. The data collection interval is set in the HP Management Agents Control Panel applet under Windows Control Panel Settings. Alarms are sent to the configured destinations through SNMP and e-mail.

In order to set thresholds, the user must have Administrator Rights and have READ-WRITE or READ-CREATE access in the SNMP security settings.

Information Availability to a WMI Consumer Top

For Windows 2000, the formatted OS performance data is available by registering a Windows WMI provider that supplies the formatted final OS performance data. The data is populated in WMI under the specific classes as follows:

Namespace: root\default

Object Class: CPQ_System_Performance

Sub–classes:

Under .net, the formatted data is also available under the WMI CIMV2 namespace as:

Namespace: root\CIMv2

Sub-classes of CIM_StatisticalInformation\Win32_Perf\Win32_PerfFormattedData
