List all nodes from OMU server using opcnodes

By default OMU-L have a utility to control node management called opcnode it is similar to ovonodeutil.bat in OMW

You can use this tool to list all nodes like

/opt/OV/bin/OpC/utils/opcnode -list_nodes

But, in one of ITRC questions the Question Author request to get only the node name which falls under certain OS type

I made some trials and I would like to share them with you:

1st using shell script and opcmon command itself.

 

1: if [ $# -eq 0 ] ; then 
2:  echo "Use $0 <windows or unix>"  
3:  echo "To list windows nodes: $0 windows" 
4:  echo "To list Unix nodes: $0 unix" 
5:  exit
6: fi
7: 
<-- more -->
8: windows=( "MACH_BBC_WIN2K3_X64" "MACH_BBC_WINXP_IPF64" "MACH_BBC_WINNT_X86" )
9: unix=( "MACH_BBC_SOL_SPARC" "MACH_BBC_HPUX_IPF32" "MACH_BBC_HPUX_PA_RISC" "MACH_BBC_LX26RPM_X64" "MACH_BBC_LX26RPM_X86" "MACH_BBC_LX26RPM_IPF64" "MACH_BBC_SOL10_X86" "MACH_BBC_AIX_PPC" "MACH_BBC_AIX_K64_PPC")
10: 
11: if [ $1 = "windows" ]; then
12:  for i in ${windows[@]}
13:  do
14:   /opt/OV/bin/OpC/utils/opcnode -list_nodes mach_type=$i |grep "Name"
15:  done
16: 
17: elif [ $1 == "unix" ];  then
18:  for i in ${unix[@]}
19:  do
20:   /opt/OV/bin/OpC/utils/opcnode -list_nodes mach_type=$i |grep "Name"
21:  done
22: fi
23: 

usage  of the command listnodes.sh < unix or windows>

---sample usage---

[root@oml ~]# listnodes.sh
Use ./listnodes.sh <windows or unix>
To list windows nodes: ./listnodes.sh windows
To list Unix nodes: ./listnodes.sh unix

[root@oml ~]# listnodes.sh windows
Name         = mahmoud-pc.mahmoudthoughts.com

[root@oml ~]# listnodes.sh unix
Name         = oml.mahmoudthoughts.com

[root@oml ~]# listnodes.sh windows |awk '{print $3}'
mahmoud-pc.mahmoudthoughts.com

[root@oml ~]# listnodes.sh unix |awk '{print $3}'
oml.mahmoudthoughts.com
[root@oml ~]#

Get Network Utilization Using VBs script

Last week I have faced challenge in responding to HP support (ITRC) thread regarding collecting Network utilization for Operation Manger to evaluate it against threshold.

Infrastructure SPI contain some policies for Monitoring network utilization but it is quite complicated (but efficient) as it has various  mathematical calculations.

Any way the script I have provided was just for calculating the utilization based on two factors total bytes transferred per second and the bandwidth.

We can get this data using WMI through "Win32_PerfFormattedData_TCPIP_NetworkInterface" class located on namespace "root\CIMV2"
We can use the attributes below to match factors stated above:

BytesTotalPersec
CurrentBandwidth

Network utilization calculation:
BytesTotalPerSec / CurrentBandwidth * 100

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\Root\CIMV2")
Set colItems = objWMIService.ExecQuery _
("select * from Win32_PerfFormattedData_TCPIP_NetworkInterface ") 
For Each objItem in colItems
bytesTotal = objitem.BytesTotalPersec * 8
bandwidth = objItem.CurrentBandwidth
result = FormatNumber(( bytesTotal / bandwidth) * 100)
output = objitem.Name & " Network Bandwidth: " & result & " % Utilized"
WScript.Echo output
Next

Screenshot of the output.

Copy Files using VBS

 

-----copyfiles.vbs----

Dim nodeName
Dim argsObj
Set argsObj=WScript.Arguments
If argsObj.Count=1 Then
    nodeName = argsObj(0)
Else
    WScript.echo "usage: cscript.exe copyfiles.vbs <nodeName>"
    WScript.Quit (1)
End If
Set objWMIService = GetObject _
    ("winmgmts:\\" & nodeName & "\root\cimv2:Win32_Process")
errReturn = objWMIService.Create _
    ("cmd.exe /c md c:\Temp", Null, Null, intProcessID)
Wscript.Echo errReturns
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & nodeName & "\root\cimv2")
Set colFiles = _
    objWMIService.ExecQuery("Select * From CIM_DataFile Where Drive = 'C:' and Path = '\\Scripts\\' and FileName Like 'coda%'") 
	'Wscript.Echo colFiles.Count echo number of files
For Each objFile in colFiles
    strNewFile = "C:\Temp\" & objFile.FileName & "." & objFile.Extension 
   	errResults = objFile.Copy(strNewFile)
	Wscript.Echo errResults 'displaying error code
Next

------ 

This script allow copy selected files on a remote machine

usage : cscript copyfiles.vbs computername

Notes:

The script is doing the following:

1. Create Folder Named C:\temp this done by this statement " ("cmd.exe /c md c:\Temp", Null, Null, intProcessID)
   
   
2. Select files located on drive C: on folder named \scripts\ and all files starts with coda this is done by " objWMIService.ExecQuery("Select * From CIM_DataFile Where Drive = 'C:' and Path = '\\Scripts\\' and FileName Like 'coda%'") "
   
   
3. Writes those files into folder c:\temp “strNewFile = "C:\Temp\" & objFile.FileName & "." & objFile.Extension “

How to use WBEMTEST to get WMI data level 2

I got anonymous reader comment on continuing the series for how to use WBEMTEST to get WMI data

In this article I will add two points to cover in this fabulous tool

1- Connect to remote node

2- Run WQL queries.

 

Connect to remote node

usually we use wbemtest locally to access local classes, but WMI support access to remote computers naturally and for applications like PowerShell version 1 which support local scripting, it uses WMI to expand its functionality and to allow PowerShell access to remote computers.

Anyhow, we can use WBEMTEST utility to achieve this by using the connect button located on the main screen, we usually use root\ to locate our local classes like ROOT\MicrosoftIISv2 to get the status for website hosted on IIS server

but if the IIS is not hosted on my local machine I can query this server by adding \\servername\ROOT\MicrosoftIISv2 so it will look like “unified naming convention” UNC same like the one used for Windows file sharing, also you can use Credentials section to access the remote system with different account.

 

Run WQL query to retrieve data from WMI classes.

WMI supports a subset of Structured Query Language that support WMI event and WMI-Specific features which we can use to filter the content of the data (instances) within a class like select certain attributes or limit the number of instance.

My 1st encounter  to WQL was in Windows Server 2003 group policy where you can filter the group policy application to only certain set of computers based on certain attributes like OS version and Service Pack or disk free space.

In our tool we can use Query button to write our query

Press Apply to get the result

You can try to use

Select * from Win32_LogicalDisk where FreeSpace > 104857600

To list only drives where is have diskspace more than 100 MB

Launch Network Overview Map

In NNMi you may need only to launch a single MAP in your browser without having the full console view.

This is achievable by launch command available with NNMi.

http://NNMiServerName:PortNumber/nnm/launch?cmd=showNetworkOverview

for launch your node group map use the below

http://NNMiServerName:PortNumber/nnm/launch?cmd=showView&objtype=Node&nodegroup=<NodeGroup>

Example:

To launch "Routers" map:

http://NNMiServerName:PortNumber/nnm/launch?cmd=showView&objtype=Node&nodegroup=Routers

To launch the Networking Infrastructure Devices node group map you can use the command below.

Replace space with + plus sign in group name “Networking Infrastructure Devices”.

http://NNMiServerName:PortNumber/nnm/launch?cmd=showView&objtype=Node&nodegroup=Networking+Infrastructure+Devices

Tips: Enable NNMi integration with OMW

Draft Article

I found very strange trick where sometimes the integration is not working ang keep giving you error access your OMW server.

The trick is to either:

• Add the OMW server in the trusted zone in the internet explorer settings. 

OR

• Disable Internet Explorer Security Configuration. Tested 16th August 2010

By the way: I do not know what is the relation between the integration script and internet explorer settings, but I have done this step on different systems and it works.

 

Had a meeting.
